主动脉瓣脱垂的二维超声心动图诊断

TWO Dimensional Ultrasonic Cardiograms in Diagnosis of Prolapses of Aortic Valves

本文对15例主动脉瓣脱垂病人和正常对照组20例进行二维超声心动图观察。所有主动脉瓣脱垂病人临床上均有主动脉瓣返流的典型症状和体征。超声研究显示,全部病人的主动脉瓣在舒张期超过主动脉瓣环连线脱入左室流出道,结合点偏移,脱垂的瓣叶大部分星吊床样(12/15)。主动脉瓣三个瓣叶中以右冠瓣居多(7/2)。3例合并二尖瓣脱垂。正常对照组均无此现象。文章还讨论了主动脉瓣脱垂的病因及超声诊断技术。研究认为,二维超声心动图是诊断主动脉瓣脱垂最主要的无创手段。

15 Cases of aortic valve prolapse (AVP) and 20 healthy persons were examined by2D—echocardiography. Clinically, all patients with AVP had typicalsymproms and physical signs of aortic regurgitation. The study showed that aortic valves of all cases passed valvular ring line into left ventricular outflow tract during ventricular distole with a deviation of junctional point. In most of the cases the porlapsed leaf is in the shape of a hammock (12/15). Among the 3 aortic valves, the right-coronary valve prolapse prolapse is the most cost common. 3 cases were complicated with mitral valve prolapse. These manifcstations were not presented in healthy persons. The causes and echbcardiographic diagnostic techhiques for AVP were discussed. It is considerced that 2D—echocardiography is one of the mostimportant non-invasivc mcthods in diaghosing AVP
