Persistent left-sided superior vena cava: integrated noninvasive diagnosis

Persistent left superior vena cava (PLSVC) is a rare finding. We describe 5 patients with PLSVC diagnosed by a noninvasive approach, including two-dimensional (2D) echocardiogram, nuclear magnetic resonance and multislice computed tomography (MCT). In 4 cases the PLSVC was isolated ("alone PLSVC"), and in 1 case associated with a right superior vena cava.     

Implantation of a biventricular pacing system via a persistent left-sided superior vena cava

Cardiac resynchronization therapy by multisite biventricular pacing presents an additive therapeutic option in the treatment of severe heart failure. Biventricular pacemaker implantation is challenging in patients with persistent left superior vena cava. We describe in this case report the implantation of a biventricular pacemaker using a left-sided approach in a patient with persistent left superior vena cava.     

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.     

Cardioverter-defibrillator implantation in a patient with persistent left superior vena cava--a case report

A case of a successful implantation of cardioverter-defibrilator using the persistent left superior vena cava is presented. After six month of follow-up pacing and sensing parameters remained constant.     

Right ventricular pacing via left superior vena cava

Negotiating the pacing lead into the right ventricle via left superior vena cava, at times, can be difficult. We report two such cases in which pacing leads were introduced into the right ventricle via left superior vena cava, with the help of stylet tip shaped into a large pigtail loop.     

Challenging pacemaker implantation: Persistent left superior vena cava with absent right superior vena cava

A persistent left superior vena cava (PLSVC) in combination with an absent right superior vena cava (RSVC) is a rare congenital cardiovascular abnormality which is usually found by chance during pacemaker (PM) implantation. In this case we describe a PM implantation using right cephalic approach through PLSVC and coronary sinus (CS), with lead fixation in right atrium and a posterolateral branch of the CS.     

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。
