The hemodynamics, contractility and compliance of the right ventricle were examined during the early postoperative phase in 9 children operated for correction of tetralogy of Fallot. The same assessments were made in 5 patients after the transventricular closure of ventricular septal defects (control group). A further reduction of the PRV/LV quotient was observed in the Fallot group during the first 3 hours postoperatively. The contractility of the right ventricle (dp/dt max) was greatly reduced in all cases. The pressure/volume relationship of the right ventricle showed severe disturbance in compliance. The type of correction (with/without outflow tract patch or monocusp) did not appreciably affect the results. The hemodynamic changes observed in the control group (VSD) were considerably less pronounced. Apparently it is not the ventriculotomy but the infundibulectomy which is the traumatic factor of corrections in the area of the right ventricular outflow tract.
对9例接受法洛四联症矫治手术的儿童在术后早期进行了右心室血流动力学、收缩性和顺应性检查。对5例经心室闭合室间隔缺损的患者（对照组）进行了同样的评估。法洛四联症组在术后最初3小时观察到右心室/左心室商数进一步降低。所有病例中右心室的收缩性（dp/dt max）均大幅降低。右心室的压力/容积关系显示顺应性严重紊乱。矫治类型（有无流出道补片或单瓣）对结果没有明显影响。对照组（室间隔缺损）观察到的血流动力学变化明显不那么显著。显然，右心室流出道区域矫治的创伤因素不是心室切开术，而是漏斗部切除术。
