[Clinical applications of percutaneous transluminal coronary laser angioplasty].
Seven cases of coronary heart diseases underwent percutaneous transluminal coronary laser angioplasty were described. Nd:YAG laser energy was delivered by metallic-capped fiberoptic. Significant reduction of narrowing was observed at the laser sites (LAD 4 cases, LCX 1 case and RCA 2 cases) after this procedure (from 89.9% to 49.9%, P less than 0.01). Satisfactory results were achieved in all cases but one, who had acute occlusion when added PTCA after laser irradiation. The indications, maneuvers and possible complications about percutaneous transluminal coronary laser angioplasty were also discussed in this article.
