[Long-term results after coronary dilatation].
The angiographic long-term success of percutaneous transluminal coronary angioplasty (PTCA) is 80% for all patients with attempted PTCA, and 90% for all patients with acutely successful intervention. This long-term success rate results from todays acute success rate of more than 90%, even though an increasing number of more and more complex stenoses have been dilated during recent years, from a rate of restenosis of 20-30% and a success-rate exceeding 90% in patients who undergo redilatation due to a restenosis. The long-term clinical course of successfully dilated patients is considerably influenced by the progression of the underlying coronary heart disease, with a development of new hemodynamically significant stenoses in some 5% of the patients per year. A large percentage of these patients undergo successful redilatation so that aortocoronary bypass surgery can again be avoided in the majority of these cases. In a minority--mostly patients with multivessel disease - aortocoronary bypass surgery can at least be postponed. Successful PTCA results in a long-term improvement of cardiac symptoms and vocational status, perhaps even in a reduction of the incidence of myocardial infarction of cardiac death. Results on latter, derived from retrospective studies, have to be confirmed by prospective trials.
