Coronary rupture by a dilatation balloon is rare but serious complication during percutaneous transluminal coronary angioplasty (PTCA). In a series of 3700 PTCAs we encountered this complication in only three cases (0.08%). In case 1, we attempted angioplasty for a lesion of the left anterior descending artery (LAD), however, through misjudgment we dilated the diagonal branch. Cardiac shock and respiratory arrest frompericardial tamponade quickly developed. The patient received urgent surgical treatment. In case 2, the wedge of a long balloon led to the coronary rupture of the left circumflex branch. The patient was treated surgically because of re rupture after removal from the labora-tory. In the third case, although the balloon size and LAD diameter were matched, LAD rupture occurred. The patient was treated by pericardiocentesis and liga-tion of LAD. All three cases had a good subsequentclinical course after surgery. We judged that coronary rupture by dilatation balloon required complete surgical treatment because of the possibility of re-rupture or pseudoaneurysm formation. and a stand-by cardiac surgeon was present for PTCA procedure.
