Coronary dissection and total coronary occlusion associated with percutaneous transluminal coronary angioplasty: significance of initial angiographic morphology of coronary stenoses.

76 patients undergoing percutaneous transluminal coronary angioplasty (PTCA), comprising 38 consecutive patients requiring emergency coronary surgery for dissection or occlusion and 38 randomly sampled control patients who did not need emergency surgery.
