On-pump heart surgery is a surgical procedure in which the heart stops temporarily. On-pump CABG is a type of heart bypass surgery where the heart is temporarily stopped, and a heart-lung machine (cardiopulmonary bypass machine) takes over the function of the heart and lungs during the operation. This allows the surgeon to perform the bypass on a still, bloodless heart.

On-Pump Heart Surgery in India is performed by experienced cardiologists and has a relatively high success rate of up to 95%. Indian people are fortunate to have the best cardiologists and technical advances in medical science. It is better to go to a doctor in the early stage of symptoms and get a proper diagnosis.
On-Pump CABG Definition- What is On-Pump CABG?
On-pump Coronary Artery Bypass Grafting (CABG) is a surgical procedure used to treat severe coronary artery disease by improving blood flow to the heart. In this method, the patient's heart is temporarily stopped, and a heart-lung machine is used to take over the functions of the heart and lungs during surgery.
It allows the surgeon to work on a still and bloodless heart, ensuring better precision while attaching healthy blood vessels (grafts) to bypass blocked coronary arteries. On-pump CABG is especially useful for patients with complex or multiple blockages and is known for its high success rate in critical cases.
On-Pump CABG Procedure
The patient is placed under general anaesthesia to ensure they are completely unconscious and pain-free during surgery. The mid-section during the surgery is handled by a heart-lung machine, which acts like a temporary heart during the procedure to purify blood and supply it to various organs of the body. On-pump CABG has the whole procedure as the same except for some steps:
Here is the whole procedure of On-Pump Heart CABG:
- Anesthesia
The patient is placed under general anaesthesia to ensure they are completely unconscious and pain-free during surgery. - Incision & Chest Opening
A vertical incision is made along the chest, and the sternum (breastbone) is split open to access the heart. - Connecting to the Heart-Lung Machine
The patient is connected to a cardiopulmonary bypass machine, which takes over the function of the heart and lungs, circulating and oxygenating the blood. - Stopping the Heart
The surgeon temporarily stops the heart using a cold potassium-rich solution (cardioplegia). This creates a motionless and bloodless surgical field. - Graft Harvesting
Healthy blood vessels (grafts) are taken from the leg (saphenous vein), chest (internal mammary artery), or arm (radial artery). - Bypass Grafting
The surgeon carefully sews the grafts to reroute blood around the blocked arteries, restoring proper blood flow to the heart muscle. - Restarting the Heart
Once grafting is complete, the heart is gently restarted, often with electrical stimulation or warming. - Removing the Heart-Lung Machine
As the heart regains normal rhythm and function, the machine is slowly disconnected. - Closing the Chest
The breastbone is wired back together, and the chest incision is closed with stitches or staples. - Recovery Monitoring
The patient is moved to the ICU for close monitoring of heart function, blood pressure, breathing, and other vital signs.

On-Pump CABG Complications
After every surgery, there are different complications. We can say that the body heals itself and needs some recovery time. After CABG, there are irregular heartbeat and blood pressure for at least a week, and complications start fading slowly as healing completes. Here are the in-depth complications of CABG.
On-Pump CABG Complications
Stroke or Neurological Issues
Due to the use of the heart-lung machine, there's a small risk of blood clots or air bubbles causing stroke or memory loss.
Heart Attack (Myocardial Infarction)
Rarely, the heart muscle may be damaged during or just after surgery.
Arrhythmias (Irregular Heartbeat)
Most common is atrial fibrillation, which may require medication or temporary treatment.
Kidney Dysfunction or Failure
The bypass machine can affect blood flow to the kidneys, especially in older patients.
Bleeding
Post-surgical bleeding may require transfusions or a second surgery in rare cases.
Infection
At the incision site, in the lungs, or in the bloodstream — more common in diabetic or immunocompromised patients.
Lung Complications
Breathing problems, pneumonia, or fluid in the lungs can occur, especially in smokers.
Short Term Complications: On-Pump Heart CABG
- Cognitive Issues ("Pump Head")
Temporary memory loss, confusion, or difficulty concentrating — usually improves over weeks. - Fatigue and Weakness
Normal in recovery period; improves with time and cardiac rehabilitation. - Swelling in Legs
If veins were taken from the leg for grafts. - Pain or Numbness
Around the chest, arms, or legs, which generally fades.

Off-Pump vs On-Pump CABG Outcomes- Difference Between On-Pump & Off-Pump Surgery
The decision for on-pump or off-pump surgery is not taken by patients or family members, it is based on the level of the blockage and diagnosis in the heart. It is a good mortality rate or success rate for both CABG surgery is the same. It is noticed that the recovery time of on-pump is more than that of off-pump, because the heart rate is the same during the surgery.
Off-Pump vs On-Pump CABG Outcomes
The purpose of both surgeries is the same: to treat patients with large and complex heart blockages. You can understand with the help of two cases:
Multiple Blockages in the heart wall: Because of the multiple blockages, there are chances that patients have more complications and suffer from a stroke or a heart attack. This is a very complex case and chances of recurring heart attacks, It could be an emergency case, so there is a need for on-pump surgery because during surgery heart may not work properly.
Arterial Blockages: In this case, in place of the coronary arteries, other arteries supplying blood to different organs have blockages. This is not a suitable condition for a heart-lung machine, so off-pump surgery is better in comparison to on-pump surgery.
Indications of on-pump CABG
Advanced age patients also have a chance of on-pump CABG. Many indications tell of the need for CABG treatment. Here are some indications of the on-pump CABG:
- High-risk patients for cardiopulmonary bypass include renal dysfunction, Poor left ventricular function, Coagulopathy or bleeding disorders, Chronic obstructive pulmonary disease (COPD), History of stroke or transient ischemic attack (TIA).
- Multiple or complex coronary artery disease: Involvement of multiple vessels (especially three-vessel disease or left main disease) requiring precise anastomoses.
- Re-do CABG: To avoid manipulating previous grafts or scarred tissues around the heart.
- Poor visualisation or technical difficulty off-pump: Cases where the anatomy or graft sites make off-pump technically risky or unfeasible.
- Urgent or emergency cases with hemodynamic instability: If the cardiopulmonary bypass setup delays treatment.
- Patients who refuse blood transfusions, like Jehovah's Witnesses, may reduce blood loss.
- Left ventricular dysfunction needing circulatory support: Cardiopulmonary bypass helps maintain perfusion during surgery in patients with low ejection fraction.
Cost of on-pump CABG in India
On-pump CABG is an easy procedure for complex arteries; there is a different cost, based on the hospital in which the surgery is performed by doctors. It ranges from INR 1,50,000 to 3,50,000, although it is a wide range of costs, it depends on the external factors of the surgery. The latest evolved procedure (Minimally invasive) is helpful in the CABG because of the shorter recovery time.

Best Hospitals for On-Pump CABG
Apart from the treatment option, a patient considers the charges of the hospital and the surgeon. The cost of any surgery depends on the anaesthesia, medications and treatment given to the patient. There are many treatment forms depending on the condition of the patient. First and foremost is the hospital’s infrastructure and location Renowned cardiac hospitals in metro cities like Delhi, Mumbai, or Bangalore often charge more due to advanced technology, experienced surgeons, and higher operational costs.
Another major factor is the surgeon’s expertise and reputation. Cardiothoracic surgeons with extensive experience in minimally invasive techniques may have higher consultation and surgical fees. The type of minimally invasive CABG performed, such as MIDCAB, TECAB, or robotic-assisted surgery, also influences the MICS heart surgery cost in India.
