Abstract
A combined phonocardiographic and echocardiographic evaluation is presented of a patient with a mechanical prosthetic mitral valve. An intermittent sound equivalent to a prosthetic fourth sound is demonstrated and shown to be created by abrupt motion of the disc of the prosthesis with atrial systole.
摘要
本文对一名人工机械二尖瓣患者进行了心音图和超声心动图联合评估。记录到一种间歇性声音，相当于人工瓣膜第四心音，结果表明该声音是由心房收缩时瓣膜盘的突然运动产生的。
