    Abstract:
    Percutaneous transluminal coronary angioplasty (PTCA) was performed in 100 coronary heart patients with 122 vessels and 138 lesions dilated. Among these 100 cases, there were 39 complex PTCA performed. The primary success rate was 93% (93/100), was 94.3% (115/122) according to vessel dilated and was 92.1% (127/138) according to lesion dilated. In 4 cases whose lesions were located at the bifurcation of the vessel, kissing balloon technique via a single guiding catheter was applied with success. In 5 cases of total occlusion PTCA was performed with success in 4. PTCA with stent in 1. PTCA was performed in 1 cases of high risk whose LVEF was only 30% and coronary hemoperfusion pump was used during the procedure. Emergency PTCA was performed in 3 AMI patients during the acute phase and elective PTCA in 8 AMI cases after successful thrombolytic therapy. There were complications in 9 cases (9%). Among these 9 cases, 2 developed O-wave MI which recovered after medicinal therapy. One AMI complicated with heart failure was treated by emergency PTCA with success, but the patient died 10 days after PTCA due to pump failure and pulmonary infection. There were no deaths due to PTCA, nor was emergency coronary artery bypass graft (CABG) performed. These cases were followed for 1-30 months on an average of 13 months. Clinical success rate was 91.3%. The clinical success rate was 93.1% by 201Tl perfusion study. Restenosis in 7 cases was confirmed by coronary angiography. For these restenotic cases, PTCA was repeated with success in 4, CABG performed in 1, coronary atherectomy in 1, and medicinal therapy employed in 1 patient.(ABSTRACT TRUNCATED AT 250 WORDS)
