Abstract

Persistent left superior vena cava (LSVC) is a congenital anomaly with 0.3%-1% prevalence in the general population. It is usually asymptomatic but in case of transvenous lead positioning, i.e., for pacemaker or implantable cardioverter defibrillator (ICD), may be a cause for significant complications or unsuccessful implantation. Single lead ICD with atrial sensing dipole (ICD DX) is a safe and functional technology in patients without congenital abnormalities. We provide a review of the literature and a case report of successful implantation of an ICD DX in a patient with LSVC and its efficacy in treating ventricular arrhythmias.

Keywords: Implantable cardioverter defibrillator; Left superior vena cava; Floating atrial sensing dipole

Core tip: The implantation of devices in patients with left superior vena cava is often unsuccessful. In case of single lead implantable cardioverter defibrillator with atrial sensing dipole implantation, little is known about the efficacy of the device during follow-up. This case report represents not only a successful implantation, but also the first case of effectiveness of anti-tachycardia therapy during follow-up.
