肺毛细血管楔嵌压的测定常作为临床估计左房压的简易和精确方法.肺毛细血管压力曲线的用途之一是估价二尖瓣反流.压力曲线上有大的V波被认为是二尖瓣有显著反流的征象,在心脏监护室中被用来诊断“无症状二尖瓣反流”.然而有些学者认为,大V波对显著二尖瓣反流既不特异又不敏感.为此,本文复习了John’s Hopkins医院一年内所有取得血流动力学-血管造影资料的成人心导管检查,进行分析.
Measurement of pulmonary capillary wedge pressure is often used as a simple and accurate method for clinically estimating left atrial pressure.One of the uses of the pulmonary capillary pressure curve is to estimate mitral regurgitation.Variant V waves on the pressure curve are thought to be two The cricoid valve has significant signs of reflux and is used in cardiac care units to diagnose “asymptomatic mitral regurgitation.” However, some scholars believe that large V waves are neither specific nor significant for significant mitral regurgitation To this end, this article reviews all cardiac catheterization studies performed at John’s Hopkins Hospital over a one-year period for analysis of haemodynamic-angiographic data.
