CABG Surgery

What this procedure is

Coronary artery bypass graft surgery, often called CABG (pronounced like "cabbage"), is a procedure used to improve blood flow to the heart. During this surgery, a doctor creates a new path for blood to travel around a blocked or narrowed artery.

To create this new path, the surgical team takes a healthy blood vessel from another part of your body, such as your leg, arm, or chest. This healthy vessel is called a graft. One end of the graft is attached above the blockage and the other end is attached below it. This allows blood to "bypass" the narrowed area and reach the heart muscle.

What it treats or fixes

This surgery is used to treat coronary artery disease. This condition occurs when a waxy substance called plaque builds up inside the arteries that supply oxygen-rich blood to your heart. Over time, this buildup can narrow the arteries and make it harder for blood to flow through.

By improving blood flow, CABG may help with several goals:

• Relieving chest pain, also known as angina.
• Reducing shortness of breath during physical activity.
• Improving the heart's overall ability to pump blood.
• Lowering the risk of future heart-related issues.

Your clinician may recommend this procedure if other treatments, such as lifestyle changes or medications, are not enough to manage your heart health.

How common it is & where it's done

CABG is one of the most common major surgeries performed in the United States and Canada. Hundreds of thousands of these procedures are done each year to help people manage heart disease and improve their quality of life.

The procedure is performed in a hospital by a specialized medical team. This team is usually led by a cardiothoracic surgeon, a doctor who specializes in operating on the heart and chest. They work alongside anesthesiologists, surgical technicians, and specialized nurses to ensure the procedure goes as planned.

Recovery: What to Expect

After surgery, you will likely spend about four to seven days in the hospital. You will start in the Intensive Care Unit (ICU), where the care team monitors your heart rate and blood pressure very closely. Your clinician may encourage you to sit up and even walk a short distance within a day or two to help your circulation and lungs.

Once you return home, full recovery usually takes six to twelve weeks. You will focus on healing your incisions (the surgical cuts) and slowly increasing your activity level. It is important to follow your team's guidance on lifting and movement. You should contact your clinician if you notice any of the following:

• A fever or chills.
• Increased redness, swelling, or drainage from your incisions.
• New or worsening shortness of breath or chest pain.

Risks & Possible Complications

Like any major procedure, CABG has risks that your surgical team works hard to prevent. Common risks include bleeding or infection at the site of the surgery. Some patients may develop an arrhythmia, which is an irregular heart rhythm that your clinician can often manage with medication.

Other possible complications can include kidney or lung issues. While more serious risks like stroke are possible, they are less common. Your medical team will review your health history to create a plan that minimizes these risks and ensures you are monitored closely throughout your stay.

Outcomes & Long-Term Results

The primary goal of CABG is to restore blood flow to the heart. Most patients find that their symptoms, such as angina (chest pain) and shortness of breath, improve significantly after they recover. This often allows for a more active lifestyle and a better quality of life.

While the surgery bypasses blocked arteries, it does not "cure" the underlying heart disease. To keep your heart healthy for the long term, your clinician may recommend:

• Taking prescribed medications for blood pressure or cholesterol.
• Eating a heart-healthy diet.
• Quitting smoking if you currently smoke.
• Participating in cardiac rehabilitation, which is a supervised program of exercise and education.

Emotional Support & Reassurance

It is very common to feel a range of emotions after heart surgery, including feeling tired, irritable, or even a bit "blue." These feelings are often a normal part of the body's response to major surgery and usually improve as you regain your strength.

Reaching out for support can make a big difference. Your clinician may suggest joining a support group or talking with a counselor to help you navigate the recovery process. Remember that healing takes time, and your healthcare team is there to help you feel confident and supported as you get back to your daily routine.

Why doctors recommend it

Clinicians usually suggest Coronary Artery Bypass Graft (CABG) surgery when the arteries that supply blood to the heart muscle become severely narrowed or blocked. This condition is called coronary artery disease. It happens when a waxy substance called plaque builds up inside the arteries, making it harder for oxygen-rich blood to reach the heart.

Your clinician may recommend this surgery if you have blockages in several heart arteries or if the main artery on the left side of your heart is narrowed. In many cases, CABG is considered when other treatments, such as lifestyle changes, medications, or less invasive procedures like stents (small mesh tubes used to keep arteries open), may not be the best option for your specific heart health.

Urgent vs planned treatment

For many people, CABG is a planned procedure. This means you and your healthcare team have time to discuss the benefits and prepare for the surgery in advance. This is often the case when symptoms like chest pain are stable, but the blockages are significant enough to require a long-term solution to protect the heart.

In other situations, the surgery may be performed urgently. If a person is having a heart attack or if their symptoms suddenly become much worse, a clinician may decide that surgery is needed right away. This is done to restore blood flow quickly and help prevent further damage to the heart muscle.

Goals of treatment

The main goal of CABG surgery is to create a new path for blood to flow to the heart. By "bypassing" the blocked sections of the arteries using a healthy blood vessel from another part of the body, the surgery helps the heart muscle get the oxygen it needs to function properly.

Successful treatment often leads to several health improvements, including:

• Relief from chest pain (angina) and shortness of breath.
• Improved energy levels and the ability to return to daily activities and exercise.
• A lower risk of having a heart attack in the future.
• Better overall heart pumping function and long-term survival.

Who may benefit

Coronary artery bypass graft (CABG) surgery is often recommended for people with severe coronary artery disease. This condition occurs when the arteries that supply blood to the heart muscle become narrowed or blocked by a buildup of plaque, which is a fatty material. When these blockages are significant, they can limit the amount of oxygen-rich blood reaching the heart.

Your clinician may suggest this procedure if you have blockages in several heart arteries or in the "left main" coronary artery, which provides a large portion of the heart's blood supply. It is also a common option for people who continue to have chest pain (angina) or shortness of breath despite taking medications or having other procedures like a stent, which is a small mesh tube used to keep an artery open.

In some cases, CABG may be recommended if the heart muscle has become weak or if you have diabetes and multiple blocked arteries. The goal of the surgery is to create a new path for blood to flow, which can help improve your quality of life and reduce the risk of future heart problems.

When it may not be the right option

While CABG is a common and effective surgery, it may not be the right choice for everyone. Your care team will look at your overall health, age, and the specific layout of your heart's blockages. If the blockages are small or can be safely managed with lifestyle changes and medications, surgery might be delayed or avoided.

For some patients, a less invasive procedure like angioplasty or stenting may be a better fit. These options do not require a large incision and often have a shorter recovery time. Your clinician may also consider whether other health conditions, such as severe lung or kidney disease, might make the recovery from a major surgery more difficult.

Ultimately, the decision depends on a balance of risks and benefits. If the heart muscle is already very severely damaged or if the patient is extremely frail, the care team might explore alternative ways to manage symptoms and protect heart health.

Questions to ask your care team

Deciding on heart surgery is a big step. It is helpful to talk openly with your cardiologist and surgeon to understand why they are recommending this path. Here are some questions you may want to bring to your next appointment:

• Why is CABG the best option for me compared to a stent or medication?
• How many of my arteries need to be bypassed?
• What are the specific goals for my heart health after this surgery?
• What are the most common risks for someone with my health history?
• How long do you expect my hospital stay and home recovery to take?
• What lifestyle changes will I need to make after the procedure?

In the procedure room

When you arrive in the operating room, you will be cared for by a large team of specialists. This team usually includes your heart surgeon, an anesthesiologist (a doctor who manages sleep and pain), and several specialized nurses and technicians. The room is filled with advanced equipment designed to monitor your health every second of the surgery.

High-level steps

The main goal of the surgery is to create a new path for blood to reach your heart muscle. To do this, the surgeon takes a healthy blood vessel from another part of your body, such as your leg, arm, or chest. This healthy vessel is called a graft.

The surgeon attaches one end of the graft above the blocked artery and the other end below it. This allows blood to "bypass" the narrow or blocked area. During the procedure, your clinician may use a heart-lung machine. This machine temporarily takes over the work of your heart and lungs, allowing the surgeon to work while the heart is still.

Anesthesia and pain control

You will be given general anesthesia before the surgery begins. This means you will be in a deep sleep and will not feel any pain or be aware of the procedure. The anesthesiologist stays with you the entire time to adjust your medicine and keep you safe.

After the surgery, you may feel some soreness, pressure, or numbness in your chest or at the site where the graft was taken. Your care team will use various medications to help you stay comfortable as you wake up and begin your recovery.

Monitoring and safety steps

Your safety is the top priority throughout the procedure. The team uses several monitors to track your heart rate, blood pressure, and the amount of oxygen in your blood. They may also place small tubes, called lines, into your blood vessels to check your heart's performance and provide fluids or medicine quickly.

These monitoring steps allow the surgical team to see exactly how your body is responding to the surgery. By watching these levels closely, they can make immediate adjustments to keep your heart and other organs working properly.

Immediately after the procedure

Once the surgery is finished, you will be moved to a recovery area or an Intensive Care Unit (ICU). You will likely have a breathing tube in your throat to help you breathe until you are fully awake and can breathe on your own. You may also have chest tubes, which are used to drain extra fluid from around the heart to prevent pressure and help the area heal.

It is normal to feel groggy, thirsty, or have a sore throat when you first wake up. You might also notice various wires and tubes connected to your body. These are used to monitor your heart rhythm and provide nutrition or medicine while you recover from the anesthesia.

Typical procedure length

A CABG surgery typically takes between 3 and 6 hours. The exact time depends on how many bypasses are needed and your specific medical history. Your surgical team will provide updates to your family or loved ones during the procedure to let them know how things are going.

Common approaches (open vs minimally invasive)

The most common method for coronary artery bypass graft (CABG) surgery is traditional open-heart surgery. In this approach, the surgeon makes an incision down the center of the chest and divides the breastbone (sternum) to reach the heart. This allows the medical team to view and treat multiple blocked arteries at once. During this procedure, a heart-lung bypass machine is typically used to pump blood and oxygen for the body, allowing the heart to be stopped temporarily while the surgeon works.

Minimally invasive approaches are an alternative for some patients. Instead of a large chest incision, the surgeon makes small cuts between the ribs. This method often avoids cutting the breastbone and may result in a shorter recovery time. One type, known as minimally invasive direct coronary artery bypass (MIDCAB), is often performed while the heart is still beating (off-pump), meaning a heart-lung machine is not used. Your clinician may suggest this option if the blockages are located in arteries that are easy to reach through small openings.

Partial vs total

In most cases, the goal of bypass surgery is complete revascularization. This means the surgeon attempts to bypass every major artery that has a significant blockage. Traditional open surgery is often chosen for this purpose because it gives the surgeon access to the entire heart, allowing them to place grafts on multiple vessels during a single operation.

In specific situations, a limited or partial approach may be appropriate. For example, if a patient has multiple blockages but is not healthy enough for a long, complex open surgery, the doctor might fix only the most critical artery using a minimally invasive technique. Sometimes, doctors use a "hybrid" approach, where surgery is used for one major artery and stents (small mesh tubes) are used to open others. This approach is not always applicable and depends on your specific anatomy and overall health.

Revision or repeat procedures

Bypass grafts are designed to last for many years, but it is possible for them to become narrowed or blocked over time. If symptoms return, a repeat operation (redo CABG) might be considered. However, repeat surgeries are generally more technically difficult than the first surgery due to scar tissue and the presence of existing grafts.

Because of the increased complexity of revision surgery, your care team may look for other options first. For instance, they might recommend medication adjustments or placing a stent inside the narrowed graft or native artery. A second surgery is usually reserved for cases where these less invasive options are not suitable.

Tests and imaging that may be done

Before your surgery, your healthcare team needs a clear picture of your overall health. This helps them plan the procedure and ensure your body is ready for anesthesia. You may undergo several common tests in the days or weeks leading up to your operation:

• Electrocardiogram (ECG or EKG): This test records the electrical activity of your heart to check its rhythm and detect any irregularities.
• Blood tests: These are used to measure how long it takes your blood to clot, check your complete blood count, and evaluate how well your liver and kidneys are working.
• Chest X-ray: This creates images of your lungs and the size of your heart to check for any underlying issues.
• Cardiac catheterization: If this was not done recently to diagnose your condition, your doctor may perform it to map out exactly which arteries are blocked.

Medication adjustments

Your doctor will review all the medicines, vitamins, and herbal supplements you currently take. Some medications can increase the risk of bleeding or interact with the anesthesia used during surgery.

Your healthcare provider may ask you to stop taking certain drugs for a specific time before the procedure. Common adjustments include:

• Blood thinners: Medicines that prevent blood clots (anticoagulants) or aspirin may need to be paused to reduce bleeding risks.
• Diabetes medications: If you take insulin or pills for diabetes, you will receive specific instructions on how to manage your dosage, especially since you will be fasting.
• Supplements: You may need to stop taking herbal supplements or vitamins, as some can affect blood clotting or blood pressure.

Important: Do not stop taking any medication unless your clinician specifically instructs you to do so. If you are unsure about a specific pill, ask your care team for a written schedule.

Day-before and day-of instructions

Preparing your body and home for surgery helps reduce the risk of infection and complications. Your hospital will likely provide a detailed checklist, which often includes the following steps.

The day before surgery:

• Fasting: You will usually be asked not to eat or drink anything after midnight. This keeps your stomach empty, which is safer for anesthesia.
• Skin preparation: You may need to shower with a special antiseptic soap (such as chlorhexidine) to kill bacteria on your skin.
• Packing: Bring comfortable, loose-fitting clothes for your recovery. Leave valuables, such as jewelry, watches, and large amounts of money, at home.

The day of surgery:

• Hygiene: You might be asked to shower again. Do not apply lotions, powders, or makeup.
• Personal items: You will need to remove contact lenses, dentures, and nail polish before going into the operating room.
• Hair removal: If hair needs to be removed from the surgical site, the medical team will usually do this at the hospital with clippers. Avoid shaving the area yourself at home to prevent small cuts or irritation.
• Pre-surgery medication: A nurse may give you a mild sedative to help you relax before you are taken to the operating room.

General surgical risks

As with any major operation, coronary artery bypass graft (CABG) surgery carries some general risks. Your healthcare team will evaluate your overall health, age, and medical history to understand your specific risk level. Common surgical risks include:

• Bleeding: This may occur during the surgery or afterward.
• Infection: Bacteria can sometimes enter the incision site on the chest or where the healthy blood vessel was removed (such as the leg or arm).
• Anesthesia reactions: Some patients may have a reaction to the medication used to put them to sleep during the procedure.
• Blood clots: Clots can form in the legs or travel to the lungs, which is why movement and special stockings are often used during recovery.

Procedure-specific complications

Because this surgery involves the heart and blood vessels, there are specific side effects that clinicians watch for. One of the most common issues is an irregular heartbeat, also known as an arrhythmia. This often happens in the first few days after surgery and is usually temporary.

Other possible complications include:

• Memory or concentration issues: Some patients experience "fogginess" or trouble thinking clearly after surgery. This is sometimes related to the use of the heart-lung machine and often improves with time.
• Kidney changes: The kidneys may not work as well temporarily after the operation.
• Chest issues: Some patients experience inflammation causing low-grade fever and chest pain, or issues with the breastbone (sternum) healing properly.
• Heart or brain events: While less common, there is a risk of heart attack or stroke during or following the surgery.

How complications are treated

Your care team focuses heavily on prevention and early treatment. You will likely stay in an Intensive Care Unit (ICU) immediately after surgery so nurses and doctors can constantly monitor your heart rate, blood pressure, and oxygen levels. If an irregular heartbeat occurs, your clinician may prescribe medication or use a temporary pacemaker to correct the rhythm.

Infections are generally treated with antibiotics and wound care. If the kidneys are stressed, the medical team may use medications or temporary dialysis to support them until they recover. Before you leave the hospital, your team will teach you how to spot signs of trouble—such as fever or redness at the incision—so you can seek help quickly if needed.

Pain control medicines

Managing discomfort is a key part of your recovery after surgery. Your clinician may use a combination of different medicines to help you feel comfortable enough to move and breathe deeply. This often includes common options like acetaminophen or non-steroidal anti-inflammatory drugs (NSAIDs), which help reduce swelling and pain.

In some cases, stronger prescription pain relievers may be used for a short period immediately after the procedure. Your care team will tailor this plan to your specific needs. It is important to tell your clinician about any allergies or if you have a history of stomach or kidney issues, as these can affect which medicines are safest for you.

Antibiotics

Antibiotics are medicines used to prevent or treat infections caused by bacteria. To help keep your incision sites—the areas where the surgeon worked—healthy and free of infection, your clinician will likely give you antibiotics shortly before the surgery begins. These are often continued for a brief period afterward while you are recovering in the hospital.

Using these medicines helps lower the risk of infection in the chest or the areas where the healthy blood vessels were taken. Your healthcare team will carefully check your medical history for any antibiotic allergies before starting these treatments to ensure your safety.

Blood thinners and clot prevention

After CABG surgery, it is vital to keep blood flowing smoothly through your new bypass grafts. Your clinician may prescribe medicines often called "blood thinners," which include antiplatelets and anticoagulants. These help prevent blood clots from forming, which could block the new vessels or lead to other heart issues.

• Aspirin: Many patients begin taking daily low-dose aspirin shortly after surgery to help keep the grafts open and working properly.
• Other medications: Depending on your heart rhythm and health history, your clinician might use other types of thinners to provide extra protection against clots.

Because these medicines change how your blood clots, they can increase the risk of bruising or bleeding. Your clinician will monitor you closely, and it is important to discuss any other supplements or medications you take to avoid potential interactions.

Emergency warning signs

While recovery takes time, certain symptoms require immediate attention. You should call 911 or go to the nearest emergency room if you experience sudden or severe changes in how you feel.

• Chest pain: Sudden pain, pressure, or tightness in your chest, especially if it feels like the angina you had before surgery.
• Breathing trouble: Severe shortness of breath that does not get better when you rest.
• Signs of stroke: Sudden numbness or weakness (especially on one side of the body), confusion, trouble speaking, or vision changes.
• Fainting: Passing out or feeling extremely lightheaded.

Call your surgeon or clinic if…

Your care team will give you specific instructions on when to contact them directly. Generally, you should reach out if you notice signs of infection or fluid buildup.

• Fever: Chills or a temperature higher than 100.4°F (38°C), or the specific limit set by your doctor.
• Incision changes: Redness, warmth, swelling, or drainage (oozing) around your chest or leg incisions.
• Rapid weight gain: Gaining more than 2 to 3 pounds in a day, which may be a sign of fluid retention.
• Heart rhythm changes: A fast, slow, or irregular heartbeat (palpitations) that feels new or different.

Expected vs concerning symptoms

It is helpful to know what is part of the normal healing process and what might indicate a complication.

Pain and soreness

Most people feel soreness in the chest and legs. This usually improves with pain medication and time. However, you should seek help if pain suddenly gets worse or is not relieved by your prescribed medicine.

The breastbone (sternum)

Your chest bone needs time to heal. Mild soreness is expected. However, call your doctor if you feel clicking, grinding, or movement in your breastbone when you move, cough, or breathe.

Leg swelling

If a vein was taken from your leg, some swelling in that area is common. However, significant swelling, redness, or pain in the calf could be a sign of a blood clot and needs medical assessment.

Non-surgical treatments

Before suggesting surgery, your clinician may recommend other ways to manage heart disease. These often include lifestyle changes like eating a heart-healthy diet, staying active, and quitting smoking. These steps help slow the buildup of plaque, which are fatty deposits that can clog your arteries.

Medications are also a key part of non-surgical care. Your doctor might prescribe medicines to lower your cholesterol, manage your blood pressure, or prevent blood clots. In some cases, a less invasive procedure called angioplasty may be an option. This involves using a small balloon and a mesh tube called a stent to open a blocked artery without the need for major surgery.

Watchful waiting

If your heart condition is stable and your symptoms are not severe, your care team might choose a "watchful waiting" approach. This means you will have regular check-ups and heart tests to monitor your health closely while continuing with medications and lifestyle improvements.

This approach allows you and your clinician to see how well your body responds to non-surgical treatments. If your symptoms remain under control and your heart function stays strong, surgery may not be needed immediately. However, you will need to report any new or worsening symptoms to your care team right away.

When surgery becomes the best option

Surgery usually becomes the best choice when blockages are too severe or complex for other treatments to work safely. For instance, if the main artery on the left side of your heart is very narrow, surgery is often the safest way to ensure your heart gets enough blood.

Your clinician may also recommend surgery if you have blockages in several different arteries or if you have diabetes. Research has shown that for people with multiple blocked vessels, surgery can often provide better long-term protection against heart attacks than stents alone. Other signs that it may be time for surgery include chest pain (angina) that does not improve with medicine or a weakening of the heart muscle.

Hospital services that commonly perform this surgery

Coronary artery bypass graft (CABG) surgery is typically performed in hospitals with specialized heart centers. These facilities have dedicated operating rooms and advanced technology specifically for cardiac care. A team of experts, including cardiothoracic surgeons (doctors who specialize in heart and chest surgery) and anesthesiologists, works together to perform the procedure.

After the surgery, patients are usually moved to a Cardiovascular Intensive Care Unit (CVICU). This is a specialized area where nurses and doctors provide constant monitoring as you begin your recovery. Later, you may be moved to a "step-down" unit or a general cardiac ward as you get stronger and prepare to go home.

Patient resources and support services

Recovery from heart surgery involves more than just physical healing. Many hospitals offer cardiac rehabilitation programs. These programs provide supervised exercise, education on heart-healthy living, and emotional support to help you regain your strength and confidence after surgery.

Other helpful resources often include:

• Nutritional Counseling: Registered dietitians can help you create a heart-healthy eating plan to manage cholesterol and blood pressure.
• Support Groups: Connecting with others who have had similar heart procedures can provide emotional comfort and practical tips for daily life.
• Social Work and Case Management: These professionals help coordinate your care, assist with insurance questions, and arrange for any equipment or home health services you might need after discharge.

Questions for choosing where to have surgery

Choosing where to have your surgery is an important decision. Your clinician may recommend a specific hospital based on your needs, but you can also ask questions to feel more comfortable with your choice. Consider using this checklist when talking to your healthcare team:

• How many CABG procedures does this hospital and surgical team perform each year?
• What are the hospital’s quality ratings or success rates for heart bypass surgery?
• Is there a dedicated cardiac intensive care unit with staff trained specifically in heart recovery?
• Does the hospital offer an on-site cardiac rehabilitation program to help with recovery?
• How will the hospital team coordinate my follow-up care with my regular cardiologist or primary doctor?

Conditions commonly treated by this procedure

Coronary Artery Bypass Graft (CABG) surgery is most often used to treat coronary artery disease. This condition occurs when the arteries that supply blood and oxygen to your heart muscle become narrow or blocked. This narrowing is usually caused by a buildup of fatty material called plaque, a process known as atherosclerosis.

Your clinician may recommend this procedure if you have:

• Severe blockages: When one or more of the main heart arteries are too narrow for blood to flow easily to the heart muscle.
• Left main coronary artery disease: A blockage in the primary artery that supplies the left side of the heart.
• Complex heart issues: Situations where other treatments, such as medicine or stents (small mesh tubes used to keep arteries open), may not be enough to restore healthy blood flow.

In some cases, CABG is performed to help prevent a heart attack or to restore blood flow if a heart attack has already caused damage to the heart muscle.

Related symptoms people search for

People who may need CABG surgery often experience symptoms related to reduced blood flow to the heart. These symptoms can vary from person to person, and your clinician can help determine if they are related to a heart condition.

Commonly reported symptoms can be associated with heart disease and may include:

• Angina: This is chest pain, pressure, or a squeezing feeling that often happens during physical activity or stress.
• Shortness of breath: Feeling winded or having trouble breathing, even during light tasks or while resting.
• Fatigue: Feeling unusually tired or lacking energy, which may happen because the heart is working harder to pump blood through narrowed vessels.
• Discomfort in other areas: Some people feel pressure, aching, or numbness in their neck, jaw, back, or arms.

It is important to remember that these symptoms do not always mean you need surgery. If you notice new or worsening symptoms, you should seek an evaluation from a healthcare professional to discuss your heart health.

Evidence overview

Coronary Artery Bypass Graft (CABG) surgery is a well-established procedure used to treat severe coronary artery disease. This condition happens when a waxy substance called plaque builds up in the arteries, blocking blood flow to the heart. Medical evidence shows that by creating a new path for blood to flow around these blockages, surgery can restore blood supply to the heart muscle.

Research suggests that for many patients with multiple blocked arteries, this surgery is highly effective. Studies indicate it can relieve symptoms like chest pain (angina) and may help people live longer compared to medication alone. Your doctor uses this evidence to determine if surgery is the right choice for your specific heart condition.

Safety notes and individualized care

Like any major operation, CABG surgery has risks. Your healthcare team will evaluate your personal health history to understand your specific safety needs. Common risks include bleeding, infection at the incision site, and irregular heartbeats (arrhythmias). Less commonly, some patients may experience temporary memory problems or confusion after the procedure.

Surgeons tailor the operation to reduce these risks. For example, they look at factors like your age, kidney function, and whether you have diabetes. Depending on your needs, your surgeon may use a heart-lung machine to support your body during surgery, or they may perform "off-pump" surgery on a beating heart if that is safer for you.

Recovery typically begins in an Intensive Care Unit (ICU), where you are watched very closely. Specialized nurses and doctors monitor your heart rate, blood pressure, and breathing continuously. This close supervision helps the team catch and treat any complications immediately.
