摘　　要：目的探讨三尖瓣适当切开(TVD)技术在婴幼儿心脏不停跳室间隔缺损(VSD)修补手术中的应用价值。方法将589例行心脏不停跳VSD修补术的婴幼儿按是否采用TVD技术分为2组:TVD组158例采用TVD技术,非TVD组431例未采用TVD技术。比较2组体外循环(TEE)时间、住院时间,在术前与术后7d、1年行心脏彩超检查,记录术后残余漏发生率,术后7d、1年三尖瓣反流(TR)发生率。结果围手术期无死亡病例。392例进行补片修补,其中TVD组129例,非TVD组263例;197例直接缝合,其中TVD组29例,非TVD组168例。66例合并畸形患儿同期进行矫治。术后并发完全性房室传导阻滞:TVD组0例,非TVD组4例,均于术后10d内恢复窦性。随访1年,2组病例均无远期死亡,均无因TR再手术,非TVD组2例因残余漏再手术。2组TEE时间、住院时间比较差异无统计学意义(P>0.05);TVD组术后残余漏及术后7d、1年TR发生率均较非TVD组显著减少(P<0.05)。结论在婴幼儿心脏不停跳室间隔缺损修补术中,应用TVD技术安全、有效,能改善VSD的暴露,减少残余漏发生,保护三尖瓣瓣叶结构,减少术后严重TR的发生。Objective To investigate the clinical value of tricuspid valve detachment（TVD）in infants undergoing beating heart surgery for ventricular septal defect（VSD）.Methods A total of 589 infants undergoing beating heart surgery for ventricular septal defect were divided into two groups：TVD group（n=158）and non-TVD group（n=431）.The extracorporeal circulation time and hospital stay were compared between the two groups.Echocardiography was performed be-fore and 7 days and 1 year after operation to record the incidences of residual leakage and tricuspid regurgitation（TR）.Results No death occurred in all patients.Among the 589 patients,392 re-ceived patch repair（including 129 in TVD group and 263 in non-TVD group）,and 197 received di-rect suture（including 29 in TVD group and 168 in non-TVD group）.Sixty-six infants with de-formity were treated at the same time.No patients had postoperative complete atrioventricular block in TVD group.However,4 patients in non-TVD group had postoperative complete atrioven-tricular block but achieved the restoration of sinus rhythm within 10 days after operation.After follow-up of 1 year,no patients died and received reoperation for TR in both groups.In non-TVDgroup,2 patients underwent reoperation for residual leakage.There were no significant differences in extracorporeal circulation time and hospital stay between the two groups（P 〉0.05）.Compared with non-TVD group,the incidence of postoperative residual leakage and incidence of TR 7 days and 1 year after operation significantly decreased in TVD group（P 〈0.05）.Conclusion TVD is safe and effective for improving the VSD exposure,reducing the incidence of residual leakage,pro-tecting the structure of tricuspid valve leaflets and decreasing the occurrence of serious postopera-tive TR in infants undergoing beating heart surgery for VSD.
