title: [Iatrogenic lesions of the left main coronary artery].
abstract: Reoccurrence of ischemic events several months after a percutaneous transcutaneous coronary angioplasty is usually due to a restenosis. Coronary angiography rarely shows a new stenosis on another site or on the left main coronary artery. In this series, we report 5 cases of left main coronary artery stenosis which have occurred from 3 to 12 months after a prior percutaneous angioplasty. This phenomenon which has previously been described after direct cannulation of the coronaries ostia during aortic valve replacement in the 70'. This complication is related to intimal damage caused by traumatic manipulation of the left main, which can be either already minimally altered or normal. This complication is rare after percutaneous transcutaneous coronary angioplasty (0.2-1.7%) according to various series. We compare our cases to the published cases in the literature.
