While Balaji's colleagues claimed torture by the central agency, the hospital advised the Dravida Munnetra Kazhagam leader and TN power minister undergo early Coronary Artery Bypass Graft Surgery. What is Coronary Artery Bypass Graft surgery? This narrows the insides of the arteries and limits the oxygen-rich blood supply to the heart muscle. The surgery helps in diverting blood around narrowed and clogged parts of major arteries and helps in improving blood flow. There may also be instances where the graft fails or when the patient dies in or after surgery.
