Early results, complications and restenosis rates after multilesion and multivessel percutaneous transluminal coronary angioplasty

Abstract Initial results, complications, restenosis rates and clinical outcomes were compared in 78 patients undergoing multilesion and 128 patients undergoing multivessel percutaneous transluminal coronary angioplasty (PTCA). Multilesion PTCA was defined as a procedure in which a proximal PTCA site had to be crossed to dilate a distal severe narrowing and multivessel PTCA as multiple dilatations without having to cross 1 severe narrowing to dilate another. The clinical and angiographic features of the 2 groups were similar. More sites per patient were attempted among those who underwent multilesion PTCA. Primary success rate per lesion was 86% (236 of 274) among those who underwent multivessel and 73 % (155 of 211) among those who underwent multilesion PTCA (p
