Cardiac Surgery Questions

Difference between Off Pump and On Pump

Another technique with advantage of lesser patient harm is known as off-pump CAB (OPCAB) as it doesn’t utilize any pump. It doesn’t require heart lung machine. The surgery is performed on beating heart that’s why it is called as “beating heart surgery” – a highly precise, complex and skill demanding procedure. We are proud that our cardiothoracic surgery team has exceptionally excelled in this technique and has shown continued commitment towards patient safety.

It is also known as Open Heart Surgery. Heart’s and lung’s functions are replaced with a machine known as “Heart-Lung Machine”. The process of such replacement of function is known as extracorporeal (outside the body) membrane oxygenation (ECMO). The operator/technician responsible for handling and use of the equipment is known as perfusionist.

The heart-lung machine is made up of majorly three parts: a pump (either non-occlusive or occlusive roller pump), a blood oxygenator, and a blood warming device. Through plastic tubing, connection of these three parts with anatomical heart is made. Deoxygenated blood is pumped to oxygenator to remove carbon dioxide from blood. Oxygenated blood is thereafter pumped to respective artery/vein of the body.

What is ECMO

Special tubes called cannulas are put into the blood vessels that go directly into your child’s heart or bloodstream. Your child’s doctor chooses the size of the tubes based on his or her size, age, weight and the reason why ECMO is being used. The cannulas transfer the blood from the child’s heart by using a pump to push the blood through tubes to the machine where the blood receives oxygen and the carbon dioxide is removed. Next the blood is warmed to body temperature. Finally, the warm blood goes through another cannula back your child’s body.


What is TAVR

This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it adds in between a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI).

What is CABG

CABG is a surgical procedure in which one or more blocked coronary arteries are bypassed by a blood vessel graft to restore normal blood flow to the heart. These grafts usually come from the patient’s own arteries and veins located in the chest (thoracic), leg (saphenous) or arm (radial). The graft goes around the blocked artery (or arteries) to create new pathways for oxygen-rich blood to flow to the heart.  Learn More


What is Heart Lung Machine

During surgery, the heart-lung bypass machine (called “on-pump” surgery) is used to take over for the heart and lungs, allowing the circulation of blood throughout the rest of the body. The heart’s beating is stopped so the surgeon can perform the bypass procedure on a “still” heart.

What is Minimally Invasive Technique

Minimally invasive coronary artery bypass (MIDCAB) surgery is an option for some patients who require a left internal mammary artery (LIMA) bypass graft to the left anterior descending (LAD) artery
