title: Acute infarction during triple-vessel coronary angioplasty due to acute occlusion of a nonattempted vessel.
abstract: During angioplasty of the left coronary artery, an acute thrombotic occlusion of the right coronary artery occurred at the site of a borderline stenosis. The source of the unexplained chest pain at the end of the procedure was identified but the next day when inferior Q-waves appeared. It was documented by repeat angiography. The coronary angiogram of the right coronary artery preceding the angioplasty of the left coronary artery is likely to have triggered the occlusion. Chest pain during or after angioplasty without apparent cause in the dilated artery must prompt a contrast medium injection into the nonattempted artery, particularly if the latter had undergone a diagnostic study at the beginning of the procedure.
