【摘要】 目的探讨改良三尖瓣下移畸形矫治术的疗效。方法①探查三尖瓣叶情况;②将后叶、隔叶以及前叶近足侧1/3-1/2的部分,沿瓣环根部将瓣叶切下;③纵行折叠房化的右心室;④将切下的瓣叶缝合于正常三尖瓣环上;⑤自体心包加固三尖瓣环;⑥必要时双孔三尖瓣成形减少反流;⑦修补其他畸形。结果患者无围术期死亡,术后均顺利恢复。术后随访1-84个月,患者恢复正常活动,心功能恢复至Ⅰ级者10例,Ⅱ级者3例。结论改良三尖瓣下移畸形矫治术较好地保持了右心室的几何形状,疗效满意。更多还原

【Abstract】 Objective To evaluate the surgical repair efficacy of modified methods on downward displacement of tricuspid valve(DDTV).Methods ①Tricuspid valve was explored;②The leaflets of tricuspid valve were removed along tricuspid annulus,including posterior leaflet,septal leaflet and 1/3-1/2 lateral anterior leaflet;③Atrialized right ventricle was longitudinally plicated;④The leaflets were sewn to the normal valve annulus;⑤The annulus was reinforced with auto-pericardium;⑥If necessary,double-orifice technique was used;⑦The associated anomalies were corrected at same.Results There were no perioperative and late deaths.After follow-up for 1-84 months,the cardiac function of all surviving patients was markedly improved,including 10 cases in NYHA class Ⅰ and 3 in class Ⅱ.Conclusion The modified repair technique is feasible for keeping the shape of right ventricles of patients with DDTV.更多还原
