All were males, the average age being 59.7 years. Five patients had sustained previous myocardial infarctions with post-infarction angina in 2 cases and 6 presented angina only. Coronary angiograms showed stenosis in LAD (N9), LCX(N6) and RCA (N6). According to the ACC/AHA classification, 6 were categorized as type B, and 5 type C. ELCA with adjunctive PTCA were performed in all 8 patients, 1. 3 mm (energy density 14. 5 mJ) and 1.6 mm (energy density 21.0 mJ) laser catheters with 20Hz pulse frequency were used There was one failure and in another ELCA was successful but death followed the procedure. The overall result was laser success 10 out of the 11 cases and procedure success 9.展开更多
