We report a case of calcific aortic stenosis in a 79-year-old man who had undergone aortocoronary bypass. Since ordinary valve replacement was problematic because of severe annular calcification, a small annular diameter, and three patent vein grafts, we performed ultrasonic aortic valve decalcification. As a result, the pressure gradient across the aortic valve decreased from 100 mmHg to 25 mmHg, and the patient is doing well to date at two years after the operation. Although long-term results of ultrasonic aortic valve decalcification are still undetermined, it appears worth considering in cases in which ordinary valve replacement could be extremely difficult.
我们报告一例79岁男性的钙化性主动脉瓣狭窄病例，该患者曾接受过主动脉冠状动脉搭桥术。由于严重的瓣环钙化、瓣环直径小以及三根静脉桥血管通畅，普通瓣膜置换存在问题，因此我们进行了超声引导下主动脉瓣去钙化术。结果，主动脉瓣跨瓣压差从100 mmHg降至25 mmHg，患者在术后两年至今情况良好。尽管超声引导下主动脉瓣去钙化术的长期效果仍未确定，但在普通瓣膜置换可能极其困难的病例中，似乎值得考虑。
