[Course of the results observed in the 1st 100 coronary angioplasties performed in 96 patients. Experience in Lyons].
TCA is an original method of myocardial revascularisation which, when successful, enables coronary bypass surgery to be avoided. However, a certain number of failures and complications are inherent to the development of a new therapeutic technique. The object of this study is to analyse the evolution of our results with this technique to determine which factors changed as our experience increased. The methodology used was that initially described by A. Gruntzig. TCA was carried out 72 times on the left anterior descending, 20 times on the right coronary and 8 on the left circumflex coronary artery (72 single vessel, 28 multivessel disease). The primary success rate was 75% (72% for the first 50 and 78% for the second 50 procedures). Coronary bypass surgery was required within the first 24 hours of TCA in 7% of cases. Myocardial infarction (Q wave changes) was observed in 5% of cases. One patient died on the third day (occlusion of an aorto-coronary venous graft). In retrospect, taking into account the experience gained and the development of the material now available, a certain number of failures and complications could probably have been avoided. However, a certain number of complications seems to be unavoidable. TCA remains an inviting but not infallible alternative in the treatment of coronary artery disease and should be included in the medico-surgical management of this condition.
