A select group of 26, class IV unstable angina patients that had multiple lesions or multivessel disease were treated with percutaneous transluminal coronary angioplasty (PTCA). Complete revascularization was the endpoint in all patients. Seventy lesions were dilated (mean = 2.6 lesions per patient). In the tandem multi-lesion group (13 patients) 2.23 lesions per patient were approached (Range 2-3) and in the multivessel disease group (13 patients) a mean of 3.15 lesions per patient were attempted (Range 2-6). An overall success rate of 96% per patient (25/26 patients) and 95.7% primary success per lesion were achieved with no mortality. We report the results of a select group of unstable angina patients with multi-lesion or multivessel disease who underwent PTCA. A careful performance was associated with high primary success in the high risk group achieving clinical and angiographic improvement.
