A 98-year-old man from Iraq underwent a bypass surgery at the Medanta hospital in Gurugram, a statement said on November 10.

A team of cardiac surgeons, led by Dr. Naresh Trehan, performed a full coronary artery bypass surgery on the man, believed to be the oldest person to have undergone a bypass surgery. Trehan is the Chairman and Managing Director of Medanta hospital. "This was a case of blocked blood vessels complicated by the patient's advanced age. Four bypasses were done to reroute the blood around the blockages. The patient is perfectly healthy and has returned to his country," Trehan said.
