经皮导管封堵器植入术可治疗膜周部室间隔缺损(PMVSD),因PMVSD与交界区传导系统相毗邻,经皮导管封堵器植入对PMVSD患者传导系统可产生影响。PMVSD经皮导管封堵器植入后即时延长HV,大样本病例的临床研究表明心脏传导阻滞的发生率为1.9%～30.4%,国内因完全性房室传导阻滞植入永久起搏器只有0.4%。PMVSD外科修补术后永久起搏器植入率少于1%。因此,PMVSD经皮导管封堵器植入并不增加心脏传导系统损伤的风险。
Percutaneous catheter occluder implantation can treat perimembranous ventricular septal defect (PMVSD). Because PMVSD is adjacent to the junctional conduction system, percutaneous catheter occluder implantation can affect the conduction system of PMVSD patients. PMVSD percutaneous catheter occluder immediately after the extension of HV, clinical studies of large sample cases showed that the incidence of heart block was 1.9% to 30.4%, due to complete atrioventricular block implantation of permanent pacemaker Only 0.4%. PMVSD surgical repair of permanent pacemaker implantation rate of less than 1%. Therefore, implantation of a PMVSD percutaneous catheter occluder does not increase the risk of damage to the cardiac conduction system.
