Hemodynamic and angiocardiographic studies were performed in postoperative patients with tetralogy of Fallot. Pressure gradient between the right ventricle and pulmonary artery was correlated with the narrowest area in the pulmonary arterial pathway. Regurgitant fraction was also correlated with regurgitant area which was determined by preoperative area of the pulmonic annulus and width of the outflow patch. Follow-up study of postoperative patients with tetralogy indicated that those with pressure gradient less than 20 mmHg and regurgitant fraction less than 15% could be considered ideally corrected. A table was constructed for determining the most appropriate width of the outflow patch for the ideal correction.
对法洛四联症术后患者进行了血流动力学和心血管造影研究。右心室与肺动脉之间的压力梯度与肺动脉通路中最窄区域相关。反流分数也与反流面积相关，反流面积由术前肺动脉瓣环面积和流出道补片宽度决定。对法洛四联症术后患者的随访研究表明，压力梯度小于20 mmHg且反流分数小于15%的患者可被认为得到了理想矫正。构建了一个表格，用于确定理想矫正时流出道补片的最合适宽度。
