New Heart Procedure Linda talks with Dr. Lawrence Cohn, chief of cardiac surgery at the Brigham and Women's Hospital in Boston. He is one of several surgeons who have been testing a cardiac procedure called Transmyocardial Laser Revascularization -- which involves the use of a laser to drill holes in the heart muscle of patients suffering from advanced coronary artery disease. The procedure has just been approved for widespread use by the FDA. It's thought the laser channels promote the formation of microscopic collateral blood vessels nearby, thereby bringing oxygen-rich blood to otherwise starved heart muscle.
