A method is described for quantifying pulmonary regurgitation. This method is based on a comparison of the right and left ventricular stroke volumes which are determined from biplane angiocardiograms. These techniques were applied to study 18 postoperative patients with tetralogy of Fallot. In patients with an outflow patch, regurgitant fraction was well correlated with regurgitant area. The RVEDV/LVEDV ratio was also correlated well with regurgitant fraction. Although majority of patients maintained normal RV ejection fraction, there were small number of patients with large regurgitant fraction and decreased RV ejection fraction.
描述了一种定量肺反流的方法。该方法基于通过双平面心血管造影确定的右心室和左心室搏出量的比较。这些技术被应用于研究18例法洛四联症术后患者。在有流出道补片的患者中，反流分数与反流面积密切相关。右心室舒张末期容积/左心室舒张末期容积比值也与反流分数密切相关。尽管大多数患者右心室射血分数维持正常，但仍有少数患者反流分数较大且右心室射血分数降低。
