This study characterizes left ventricular performance early after aortic valve replacement for severe isolated aortic regurgitation. Gated radionuclide ventriculography studies in 13 patients showed that left ventricular end-diastolic volume was reduced after surgery and that ejection fraction dropped significantly. Despite the fall in ejection fraction, the postoperative cardiac index was significantly greater than the preoperative value. Radionuclide ventriculography is a useful and reliable means of noninvasively assessing left ventricular function soon after aortic valve replacement for aortic regurgitation.
本研究对重度单纯主动脉瓣反流患者主动脉瓣置换术后早期的左心室功能进行了特征性描述。对13例患者进行的门控放射性核素心室造影研究显示，术后左心室舒张末期容积减小，射血分数显著下降。尽管射血分数降低，但术后心脏指数显著高于术前值。放射性核素心室造影是主动脉瓣反流患者主动脉瓣置换术后不久无创评估左心室功能的一种有用且可靠的方法。
