Abstract
Coronary angiography in a 55-year-old man with coronary heart disease and typical physical activity-induced angina revealed a subtotal stenosis in the middle third of the right coronary artery while left ventricular function was normal. Percutaneous transluminal coronary angioplasty (PTCA) was performed in January 1989, achieving a residual stenosis of less than 50%. However, restenosis of more than 90% developed within six months, necessitating another PTCA, followed immediately by implantation of a metal (Palmaz-Schatz) stent in the stenotic area. No stenosis was demonstrable afterwards. Maintenance medication with anticoagulants (phenprocoumon) and platelet-function inhibitors (aspirin and dipyridamole) was instituted and repeat angiography three months later demonstrated good dilatation results without any restenosis.
