The present study is a prospective analysis of a series of consecutive valve replacement and combined (valvular plus coronary artery) operations performed without left ventricular decompression. Results indicate that left ventricular venting (direct or indirect) is unnecessary provided that cardioplegic arrest is used, that the venous line is positioned in the right atrium, and that left-sided pressures are monitored. Left ventricular distention, as measured by left ventricular pressure recording, did not occur; air embolism, as determined clinically and by electroencephalographic (EEG) monitoring, was not encountered. The routine use of a left ventricular vent has been abandoned in most intracardiac operations at our center.
本研究是对一系列在未进行左心室减压情况下连续进行的瓣膜置换术及联合（瓣膜加冠状动脉）手术的前瞻性分析。结果表明，只要采用心脏停搏法、将静脉管路置于右心房并监测左侧压力，就无需进行左心室排气（直接或间接）。通过左心室压力记录测量，未发生左心室扩张；经临床判定及脑电图（EEG）监测，未出现空气栓塞。在我们中心的大多数心脏内手术中，已不再常规使用左心室排气装置。
