Percutaneous transluminal coronary angioplasty with cardiopulmonary bypass for stenosis of the most proximal part of the left anterior descending coronary artery.

An 85 year old man with unstable angina pectoris was treated successfully with percutaneous transluminal coronary angioplasty supported by cardiopulmonary bypass and intra-aortic balloon pumping. Coronary angiography had shown stenoses in both the left main stem and left anterior descending coronary arteries. Drug treatment had been ineffective and he was too old for coronary arterial bypass grafting.
