Abstract
In the late seventies coronary angioplasty was limited to the treatment of simple lesions only (i.e. type A or type B1 according to the classification of the American Heart Association). The method was also restricted to patients with single-vessel-disease. The success-rate in these short, non calcified, non thrombotic lesions of rather straight segments was about 70%. Severe complications (Q-infarction, emergency CABG, death) happened in 5 to 10% of the patients, and restenosis occured in 20 to 40%. Today, more complex lesions (type B2 and C following the AHA-classification) are treated and patients with multi-vessel-disease are the majority. Operator experience and an incredibly rapid development of technology resulted in a success rate of 99% in type A and B1 lesions and 90% with more complex stenoses. Chronic old occlusions can now be recanalized in about 70% of the patients. Severe complications (Q-wave myocardial infarction, emergency coronary bypass operation, or death) happen in no more than 1% of the patients treated today.
