Persistent left superior vena cava,fibrous remnant of the right superior vena cava and ventricular septal defect

We have reported a case of persistent left superior vena cava associated with a nonfunctional right superior vena cava. Twenty-nine cases of this venous pattern with anatomic study were found in the literature. Among these, as in the case here reported, only 3 showed an anatomic vestige, in the form of an atretic cord, of the right superior vena cava. In our case a ventricular septal defect was also present, which yielded certain features like those in origin of both great vessels from the right ventricle.The venous anomalies yielded an unusual course of the catheter during cardiac catheterization. These anomalies were identified by venous angiocardiography.     

Persistent left superior vena cava

Persistent left superior vena cava -- a case report. A case of a 72-year-old female admitted for pacemaker implantation is presented. During the procedure, persistent left superior vena cava was found. Pacemaker was inserted via right subclavicular vein.     

Persistent left superior vena cava and pacemaker implantation

Our study group read with interest the paper from Vijayvergiya et al describing the implantation of an implantable cardioverter-defibrillator lead in the presence of the persistence of the left superior vena cava.The issue of the identification a persistent left superior vena cava is of paramount importance in interventional cardiology,being the most common venous anomaly of the thoracic distribution,and because it may create some problem to any physician while performing a pacemaker lead implantation.In our letter we underscore the specific issues related to pacemaker implantation while encountering a persistent left superior vena cava(and maybe the absence of the right vena cava)and the workup that should be performed to obtain the preoperative diagnosis of the venous anomaly.More specifically,we consider avoiding any kind of defibrillator lead implantation through the coronary sinus for safety issues,and underscore the straightforward transthoracic ultrasound approach to identify the left superior vena cava.     

经永存左上腔静脉植入永久人工心脏起搏器1例

患者,男,60岁。因Ⅲ度房室传导阻滞择期行永久起搏器安置术,术中左锁骨下静脉穿刺因导丝异常走行发现存在永存左上腔静脉(persistent left Superior vena cava,PLSVC),通过适当地操作,将双极起搏电极置入于右心室心尖部,测试起搏阈值及感知功能良好,手术成功。
