title: Angioplasty of subacute and chronic total coronary occlusions: success, recurrence rate, and clinical follow-up.
abstract: Angioplasty of single total, subacute, or chronic coronary occlusions was performed in 90 patients. It was successful in 54 occlusions (60%), in 77% of those less than 6 weeks old, and in 44% of those of greater than 6 weeks' duration (p less than 0.005). All procedures were uneventful. Control angiography was performed in 53 (98%) patients with successful angioplasty after an average interval of 97 +/- 53 days. Stenosis had recurred in 16 patients (30%). During a follow-up period of 36 +/- 13 months, three patients died, five patients underwent coronary bypass operation, and 10 had reangioplasty. Despite an additional late angiographic recurrence of stenosis in seven patients, 36 patients revealed angiographic long-term success. In the 46 nonoperated patients, angina pectoris and exercise stress tests were substantially improved. Thus angioplasty of subacute and chronic total coronary occlusions is an uneventful procedure, the success rate depending on the duration of the occlusions. Despite a high angiographic recurrence rate, the angiographic and clinical long-term results are favorable.
