Beating-heart surgery, also called off-pump coronary bypass, operates on the coronary arteries while the heart continues to beat. A stabilising device gently holds the small area being worked on, allowing the surgeon to sew the graft in place without stopping the heart or using the heart-lung machine. The aim is to bypass blocked arteries while avoiding some effects of the machine.

Patients seeking cardiovascular surgery in Mumbai are assessed to see whether this approach suits them. It may be considered for people with a heavily calcified aorta, kidney or lung disease, or a higher risk with the heart-lung machine. The surgeon studies the angiogram to confirm that every blocked artery can be reached safely. Not every patient or artery is suitable, and the surgeon may change to the heart-lung machine during the operation if safety requires it.

The operation is performed under general anaesthesia and takes several hours. Patients usually spend the first day in intensive care, then move to a ward. Breathing exercises, early walking and physiotherapy begin soon after surgery, and the breastbone needs about six to eight weeks to heal. Medicines such as aspirin and cholesterol-lowering tablets protect the grafts.

How the Procedure Can Help

Bypass relieves chest pain, improves blood flow to the heart muscle and may improve long-term survival in selected patients. Avoiding the heart-lung machine may reduce bleeding, kidney strain and temporary memory or thinking problems in some patients, although results vary and the benefit is not guaranteed.

Risks and Considerations

Risks include bleeding, wound infection, irregular heartbeat, stroke, kidney problems, graft blockage over time and the need to switch to the heart-lung machine. Beating-heart surgery may be technically harder when arteries are small or deep in the heart. Fever, wound discharge, chest pain, breathlessness or a rapid, irregular pulse after discharge needs prompt medical review.
