The right ventricular (RV) function is very important after correction of tetralogy of Fallot (TOF) similarly to left ventricular (LV) function. The influence to RV contraction caused by RV outflow tract patch after repair of TOF is serious. There are a few literatures about contraction mode of RV but we can't see any reports about regional RV wall motion before and after surgery of TOF. This paper is the first report about RV regional wall motion and function after 20 cases of tetralogy repair. We would emphasize the following points. 1) Regional wall motion of RV at antero-basal and anterolateral is getting worse but is improved at anteroapical of RV. 2) Appropriate rate of RV systolic pressure to LV systolic pressure just after weaning from cardiopulmonary bypass and rate of patch length to RV length is below 0.5 and 0.4 respectively. 3) There is positive correlation between RV ejection fraction and wall motion at anteroapical of RV.
与左心室（LV）功能一样，法洛四联症（TOF）矫正术后右心室（RV）功能非常重要。TOF修复术后右心室流出道补片对右心室收缩的影响很严重。关于右心室收缩模式的文献较少，但我们未见到任何关于TOF手术前后右心室区域壁运动的报道。本文是关于20例四联症修复术后右心室区域壁运动和功能的首次报道。我们将强调以下几点。1）右心室前基底和前外侧区域壁运动变差，但右心室心尖前部区域壁运动得到改善。2）体外循环停机后即刻右心室收缩压与左心室收缩压的适当比例以及补片长度与右心室长度的比例分别低于0.5和0.4。3）右心室射血分数与右心室心尖前部壁运动之间存在正相关。
