Abstract

In a case with bioprosthetic tricuspid stenosis, simultaneous phonocardiogram and Doppler recordings revealed that the louder diastolic rumble in inspiration (Rivero-Carvallo sign) is related to increased tricuspid gradient caused by less prominent decrease of right atrial pressure compared with that of the right ventricle in inspiration caused by tricuspid stenosis.

摘要

在一例生物瓣三尖瓣狭窄病例中，同步心音图和多普勒记录显示，吸气时更响亮的舒张期隆隆声（里韦罗-卡瓦略征）与三尖瓣狭窄导致吸气时右心房压力较右心室压力下降不明显，从而使三尖瓣压差增加有关。（）
