We conducted ultrasonic decalcification on calcified annulus in patients with aortic stenosis (AS) using an ultrasonic operator, Sonopet (UST 2001) prior to aortic valve replacement (AVR). We studied the reliability of this method.
From January 2002 to August 2005, AVR was conducted for AS using the Sonopet in 45 patients, comprising of 18 male and 27 female subjects. The mean age was 73.3 +/- 9.7.
Artificial valves were successfully inserted at the intra-annular level in 37 patients and at the supra-annular level in 8 patients without conducting annular enlargement. In the patients with narrow annuli of less than 19 mm (23 patients), the preoperative mean annular diameter was 18.2 +/- 1.0 mm, but significantly larger artificial valves with an average diameter of 19.3 +/- 1.5 mm (p=0.003) were successfully inserted.
AVR was proved to be safe and easy by previous ultrasonic decalcification of the annuls using the Sonopet. This method was very useful because it required no enlargement of aortic annulus.
在进行主动脉瓣置换术（AVR）之前，我们使用超声设备Sonopet（UST 2001）对主动脉瓣狭窄（AS）患者的钙化瓣环进行了超声脱钙处理。我们研究了该方法的可靠性。
2002年1月至2005年8月，45例AS患者使用Sonopet进行了AVR，其中男性18例，女性27例。平均年龄为73.3±9.7岁。
37例患者人工瓣膜成功植入瓣环水平，8例患者成功植入瓣环上水平，均未进行瓣环扩大。在瓣环狭窄小于19mm的患者（23例）中，术前平均瓣环直径为18.2±1.0mm，但平均直径为19.3±1.5mm的更大人工瓣膜（p = 0.003）成功植入。
先前使用Sonopet对瓣环进行超声脱钙处理证明AVR是安全且简便的。该方法非常有用，因为它无需扩大主动脉瓣环。
