 note = {The purpus of this study is to estimate the efficacy of percutaneous transluminal coronary angioplasty (PTCA) for chronic total coronary occlusion. In 41 patients without history of sustained myocardial infarction, overall initial PTCA success rate was 75.6% and was related to duration of occlusion (88.8% success rate for occlusions of less than 3 months, 50.0% after 4 months： p<0.05). Complications were minor： no patient died or requred emergency bypass operation, and 2 patients had small aeras of myocardial infarction. Exercise tolerance improved significantly in successful cases. In 6 patients with left anterior descending artery (LAD) occlusion as single vessl disease, 3 to 5 months after successful PTCA, ejection fraction improved significantly. End-diastolic volume index had no change, but end-systolic volume index decreased significantly, and regional wall motion improved significantly in areas of hyokinesis where LAD supplied. This study shows that initial success rate of PTCA for chronic total occlusion is acceptable with low risk of serious complications, and that exercise capacity and ventricular function improve in successful cases.},
