CRT-D Upgrading in a Patient with Persistent Left Superior Vena Cava and Right Superior Vena Cava Atresia Using the Novel Active-Fixation Quadripolar Left Ventricular Lead

The persistence of left superior vena cava (PLSVC) is the most common congenital anomaly of the venous return system to the heart. Because of the increasing number of patients referred for cardiac resynchronization therapy (CRT) devices implantations, it is expected to encounter this venous anatomic variation. Left ventricular lead placement at an appropriate site is an integral and technically challenging part of successful CRT. In case of cardiac abnormalities could be difficult to achieve an optimal cardiac rhythm management devices implantation. Previous reports in patients with PLSVC highlighted the challenges to achieve an optimal cardiac rhythm device implantation. Recently, a new quadripolar active fixation left ventricular lead is available for CRT device implantation. Hereby we report a case of a device upgrading from dual-chamber pacemaker to CRT with defibrillator backup using the active fixation left ventricular quadripolar lead in a patient with PLSVC and right superior vena cava atresia.

上腔静脉-右肺动脉分流术治疗三尖瓣闭锁的术后护理

目的:总结10例上腔静脉-右肺动脉分流术治疗三尖瓣闭锁的术后护理。方法:术后采取半坐卧位,加强呼吸道护理,持续监测末梢血氧饱和度,循环系统监测护理,保持引流管通畅。结果:本组患者术后末梢血氧饱和度由(74%±9%)上升至(92%±5%)。无一例患者死亡,术后恢复良好,顺利出院。结论:术后良好的护理管理,减少了并发症的发生,提高了患者的生存率。
