Coronary artery bypass surgery is a crucial cardiac intervention that restores proper blood flow to the heart muscle. When coronary arteries become narrowed or blocked due to atherosclerosis (the buildup of plaque), it can lead to reduced oxygen supply to the heart, resulting in chest pain (angina), breathlessness, fatigue, and even heart attacks. This surgical procedure, often called CABG (Coronary Artery Bypass Graft), creates a new pathway for blood to reach the heart by bypassing the blocked arteries with healthy blood vessels from other parts of the body.

At CTS Hospitals, we specialize in advanced cardiac surgeries, including coronary artery bypass surgery, ensuring patients receive expert care, faster recovery, and improved long-term outcomes.

What Is Coronary Artery Bypass Surgery?

Coronary artery bypass surgery is a procedure that improves blood flow to the heart by rerouting it around narrowed or clogged coronary arteries. The surgery involves harvesting healthy blood vessels—usually from the leg (saphenous vein), chest (internal mammary artery), or arm (radial artery)—and grafting them to the blocked arteries. This procedure is primarily recommended for patients with severe coronary artery disease (CAD), particularly when medications, lifestyle changes, or procedures like angioplasty have failed to improve the condition.

Why Is Coronary Artery Bypass Surgery Needed?

Coronary artery bypass surgery is performed for several life-enhancing and lifesaving reasons:


  • To relieve angina (chest pain): By restoring proper blood flow, the surgery reduces pain and allows patients to resume daily activities comfortably.

  • To reduce the risk of heart attacks: Bypassing blocked arteries lowers the risk of future heart attacks, especially in high-risk patients.

  • To improve heart function: For those with weakened heart muscles due to blocked arteries or prior heart attacks, the surgery enhances cardiac performance.

  • To improve survival and quality of life: CABG significantly improves long-term survival in patients with multiple blockages or diabetes.


 

Conditions Treated with Coronary Artery Bypass Surgery

The main condition addressed by CABG is coronary artery disease, particularly when it is:

  • Severe or widespread: Multiple blockages in major arteries supplying the heart.

  • Post-heart attack: When part of the heart muscle is damaged and needs more blood flow.

  • Unresponsive to angioplasty or stents: If prior procedures have failed or are not viable.


Types of Coronary Artery Bypass Surgery

At CTS Hospitals, cardiac surgeons perform different types of CABG based on the patient's health condition and the extent of artery blockage:

  1. Traditional On-Pump CABG


This is the most common method, where the heart is temporarily stopped, and a heart-lung machine maintains circulation while grafts are placed.

  1. Off-Pump CABG


Also known as beating-heart surgery, this is done without stopping the heart. It’s ideal for patients who may face higher risks with traditional surgery and allows for quicker recovery.

  1. Minimally Invasive CABG


This results in less trauma, reduced pain, and shorter hospital stays.

  1. Robot-Assisted CABG


With robotic precision, surgeons perform highly targeted procedures through tiny incisions. This modern technique reduces scarring and speeds up recovery time.

  1. Hybrid Procedures


It’s an effective option for patients needing treatment for multiple vessels.

Who Needs Coronary Artery Bypass Surgery?

You may need CABG if:

  • You experience persistent chest pain despite medications.

  • You’ve had a heart attack, and your heart function is declining.

  • Stents or angioplasty are not effective or appropriate.


Timely intervention is critical. When untreated, blocked arteries can lead to life-threatening events. At CTS Hospitals, we guide you through every stage of treatment with compassion and precision.

Risks and Complications of CABG:

  • Bleeding and infection at the incision site

  • Irregular heart rhythms (arrhythmias)

  • Stroke or heart attack during or after surgery (rare)

  • Kidney problems, especially in those with pre-existing conditions

  • Memory issues or cognitive changes, usually temporary


Proper patient selection, preoperative planning, and postoperative care help minimize these risks significantly.

Preparing for Coronary Artery Bypass Surgery

Your care team will provide detailed instructions, which may include:

  • Adjusting medications: Blood thinners and diabetic medications may need to be paused

  • Dietary restrictions: Fasting for at least 8 hours before surgery

  • Smoking cessation: Improves healing and reduces risks

  • Postoperative planning: Arrange for help during the recovery period


At CTS Hospitals, our cardiac team ensures that every patient is physically and mentally prepared for surgery, easing anxiety and building confidence.

What to Expect During the Procedure

Here’s what typically happens:

  1. General anesthesia is administered.

  2. An incision is made down the chest or between the ribs.

  3. If needed, a heart-lung machine temporarily takes over heart function.

  4. The grafts are placed to bypass the blockages.

  5. The incision is closed, and the patient is transferred to the ICU for monitoring.


Recovery After Coronary Artery Bypass Surgery

Recovery varies by individual, but most patients start to feel better within a few weeks.Key elements of recovery include:

  • Wound care to prevent infection

  • Gradual physical activity, starting with walking

  • Heart-healthy diet, rich in fiber and low in saturated fats

  • Medications for blood pressure, cholesterol, and clot prevention

  • Cardiac rehabilitation to guide lifestyle changes and monitor progress


Patients are advised to avoid smoking, manage stress, and adopt an active lifestyle to maintain surgical benefits.

Potential Complications During Recovery

Though rare, some complications may arise post-surgery:

  • Arrhythmias like atrial fibrillation

  • Wound infection or delayed healing

  • Fluid retention or swelling

  • Depression or fatigue


Regular follow-ups with your cardiologist and adherence to recovery protocols help mitigate these issues. At CTS Hospitals, our team closely monitors patients and provides support at every step.
