[Atherectomy. A new catheterization method for coronary revascularization].
Intimal atheroma con be excised and removed by coronary atherectomy. We describe our experience from the use of this method in the first 42 patients. The procedure was successful in 40 patients, in 16 cases after adjunct percutaneous transluminal coronary angioplasty. Two patients required bypass surgery because of catheter-related injury to the coronary vessel. One of these suffered a myocardial infarction, the only infarction in the material. In-hospital complications were minor, and the average stay in hospital after the procedure was 1.6 days. Angiography in 20 patients after a median follow-up period of 116 days showed restenosis in 30%, all of whom were treated successfully with PTCA. Symptomatic improvement was reported by 74% of the patients after a median observation time of 16 months. One patient died, probably from infarction, three months after the initial treatment, one patient suffered a non-fatal infarction, and one patient underwent bypass surgery. We conclude that atherectomy is an effective and safe treatment of coronary heart disease in selected cases, mainly eccentric stenoses and ostial lesions.
