Percutaneous transluminal coronary angioplasty (PTCA) was performed in 5 differ ent kinds of complex coronary artery disease. Bi-quidwires technique was used in the patient whose lesion was at the bifurcation of vessel and autoperfusion technique in the patient with severe coro-nary artery stenosis resulting in acute myocardial infarction. The total and longer coronary occlu-sion was progressively dialated by balloon catheter with the harder quidwire (Hi-Torque standard) crossing the occlusion. The coronary dissection was repaired with autoperfussion balloon catheter under lower pressure and longer time. All procedures were successful in PTCA. The results showed that an optimal PTCA efficacy would be obtained by using different methods according to different situations.
