A patient with tetralogy of Fallot experienced isolated right ventricular failure when the right coronary artery was occluded by an encircling suture at the time of closure of the ventricular septal defect. Recognition and correction of the problem allowed weaning from cardiopulmonary bypass and an uneventful recovery. Because ventricular septal defects in tetralogy of Fallot are usually anterior and subaortic, injury to the right coronary artery, in close proximity to the superior aspect of the defect, is a potential danger. When isolated right ventricular failure occurs immediately after repair, suture occlusion of the right coronary artery should be considered as a possible cause.
一名法洛四联症患者在室间隔缺损修补时,右冠状动脉被环绕缝线阻塞,出现了单纯性右心室衰竭。对该问题的识别和纠正使得患者能够脱离体外循环并顺利康复。由于法洛四联症的室间隔缺损通常位于前方且在主动脉下方,靠近缺损上缘的右冠状动脉受到损伤是一个潜在风险。当修补后立即出现单纯性右心室衰竭时,应考虑右冠状动脉被缝线阻塞是可能的原因。
