Both heavily calcified and ostial lesions are difficult to deal with by percutaneous transluminal coronary angioplasty (PTCA) alone. Acute results are often sub-optimal, complications are more frequent, and long-term results are disappointing. Optimal stent deployment may not be possible unless satisfactory lesion dilatation is achieved and the lesion made more compliant. The use of rotational atherectomy and cutting balloon angioplasty to a calcified ostial lesion in the left circumflex coronary artery prior to stent implantation is reported.
严重钙化病变和开口处病变仅通过经皮冠状动脉腔内血管成形术(PTCA)都很难处理。急性结果往往不理想,并发症更常见,长期结果也令人失望。除非实现满意的病变扩张并使病变更具顺应性,否则可能无法实现最佳的支架置入。本文报道了在支架植入前使用旋磨术和切割球囊血管成形术治疗左旋支冠状动脉的钙化开口处病变。
