title: Percutaneous transluminal coronary angioplasty more than twice for the same coronary lesion.
abstract: To determine outcome and predictors of restenosis after three or more PTCAs for the same coronary lesion we studied 23 patients (17 patients three PTCAs; five patients four PTCAs; one patient six PTCAs). The primary success rate was 100%. Myocardial infarction was seen in one patient; there was no emergency surgery or mortality. Duration of follow-up after the last PTCA was 11-58 months (mean 26 months). Restenosis occurred in 6 of 23 patients (26.1%) after the last PTCA. The symptom-free interval before the last PTCA was less than or equal to 3 months in five of these six patients, a larger balloon for the last PTCA was used in two patients. After the last PTCA 17 of the 23 patients (73.9%) were asymptomatic; repeat angiography in seven of them revealed no restenosis. The symptom-free interval before the last PTCA was less than 3 months in eight patients, and a larger balloon was used in six of these. In nine patients the interval was greater than 3 months, and a larger balloon was used in two. When the symptom-free interval before the last PTCA was less than or equal to 3 months, restenosis occurred in two of eight patients (25%) in whom a larger balloon was used, but in three of five patients (60%) in whom a larger balloon was not used. When the interval before the last PTCA was less than or equal to 3 months five of 13 patients (38.5%) developed restenosis, but when it was greater than 3 months only one of 10 patients did so.
