Recanalization of chronic coronary artery occlusions using laser followed by balloon angioplasty.
Excimer laser angioplasty with adjunctive percutaneous transluminal coronary angioplasty of chronic coronary artery occlusions was performed using the Litvack 1.3 Z laser catheter in 80 patients in whom the occlusion could be passed by a guidewire; success rate was 89%. Angiographic follow-up revealed a restenosis rate of 33% and a reocclusion rate of 20%, and clinical follow-up showed a significant symptomatic improvement. It is concluded that laser angioplasty is a promising method for the treatment of chronic coronary artery occlusions.
