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.
