摘　　要：目的探索一种新的瓣膜成形方法。方法风湿性心脏瓣膜病患者二尖瓣10块,以功率为15～30 W,光纤芯径为300μm的Nd:YAP激光呈直角扫描照射瓣膜表层,消除钙化斑块。结果激光照射后的瓣膜表面钙化斑块部分消失、内皮细胞消失,显现其下纤维层。结论以适当功率的Nd:YAP激光照射是瓣膜形成的一种有效方法。Objective To establish a new way of cardiac valvoplasty. Methods The cardiac valve was decalcificated with the Nd ： YAP laser, then the valves before and after valvoplasty were observed under scanning electron microscope respectively. Results Calcificaled plagues dollop of the valves were almost removed. Conclusions Laser valvoplasty was proved to be an effective modality.
