Aortic valve replacement for calcifica aortic stenosis requires meticulous debridement of the aortic annulus to effect optimal valve seating. Since 1987, we have used ultrasonic energy to debride the aortic annulus during aortic valve replacement in 56 patients. In our experience, ultrasonic debridement of the annulus is superior to traditional methods of debridement, affords improved seating of the valve, and may allow placement of a larger valve. Our follow-up ranges from 2 to 32 months (mean follow-up, 13 +/- 9 months) with 0% incidence of paravalvular leak or valve failure. We advocate the use of ultrasonic debridement as an adjunctive tool in aortic valve replacement.
对于钙化性主动脉瓣狭窄进行主动脉瓣置换时，需要对主动脉瓣环进行细致的清创，以实现最佳的瓣膜就位。自1987年以来，我们在56例患者的主动脉瓣置换过程中使用超声能量对主动脉瓣环进行清创。根据我们的经验，超声清创瓣环比传统清创方法更具优势，能使瓣膜更好地就位，并且可能允许植入更大尺寸的瓣膜。我们的随访时间为2至32个月（平均随访时间为13±9个月），瓣周漏或瓣膜功能障碍的发生率为0%。我们主张将超声清创作为主动脉瓣置换中的辅助工具。
