The Department of Cardiac Surgery functions through two independent but mutually linked adult and paediatric units. Both together perform approximately 2000 operations annually. The Institute of Cardio Vascular Diseases takes great pride in affirming that it is the most experienced unit in the country performing homograft valve replacements. Possessing the first homograft valve bank in the country employing cryopreservation techniques also helps in providing for the large demand for homografts within the Institute.

The Adult Cardiac Surgical Unit performs 1200 -1500 operations annually, of which coronary artery bypass procedures form a major part. In keeping with current techniques and technological advancements, the Off Pump Coronary Artery Bypass (OPCAB) has become an important and common means of surgical revascularization.

While valve replacements are done in large numbers, special emphasis is given to repair techniques in an effort to preserve the native valves wherever possible. Novel as well as time - tested repair techniques like chordal shortening, quadrangular resection and use of artificial (PTFE) chordae are used as needed. Besides the replacement of aortic and pulmonary valves, the Unit has also performed homograft replacement of the mitral valve.
