Retaining of PTCA guide wire in the left ventricular lead and subsequent application of epicardial electrode when CRT-D implantation in a patient with severe heart failure and persistent left superior vena cava: a case report.

Implantation of a cardiac resynchronization therapy-defibrillator device in a patient with persistent left superior vena cava.

Presence of a persistent left superior vena cava (PLSVC) is generally clinically asymptomatic and discovered incidentally during central venous catheterization. However, PLSVC may cause technical difficulties during cardiac device implantation. An 82-year-old man with heart failure symptoms and an ejection fraction (EF) of 20% was scheduled for resynchronization therapy-defibrillator device (CR...

PCI techniques to aid implantation of CRT-D in a senior patient with persistent left superior vena cava

Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the vena cava, affecting about 0.5% of the general population, which poses a particular obstacle during transvenous electronic device implantation. Here, we report a successful cardiac resynchronization therapy-defibrillator device (CRT-D) implantation strategy in which techniques and devices for percutaneous coronary in...

[Pacemaker implantation via a persistent left superior vena cava].

Implantation of a single-chamber pacemaker was planned in an 83-year-old woman with sick-sinus syndrome causing dizziness, bradycardia and tachycardia. After puncture of the right subclavian vein it proved impossible to advance a guide-wire into the superior vena cava, under fluoroscopy the wire always being seen to coil in the left subclavian vein and hence passing into a caudally directed vei...

Persistent left superior vena cava. Use of an innominate vein between left and right superior caval veins for the placement of a right ventricular lead during ICD/CRT implantation.

CRT-D Implantation Through a Persistent Left Superior Vena Cava

A persistent left superior vena cava (PLSVC) was present in a 74 year-old man with dilated cardiomyopathy undergoing implantation of a cardiac resynchronization therapy device with defibrillator (CRT-D). A dual-coil active-fixation defibrillator lead was positioned in the right ventricular apex, followed by a SonR active fixation lead in the right atrial free wall. The coronary sinus lead was a...
