Key result
Implantation of a biventricular pacing system was successfully performed in a patient with a persistent left superior vena cava by positioning leads directly through the coronary sinus.
Case Report (n=1)
Biventricular pacing systems can be successfully implanted in patients with a persistent left superior vena cava without the need for special guiding catheters.
Supports feasibility via coronary sinus in persistent left SVC; case report leaves open need for validation before wider adoption.
The presence of a persistent left superior vena cava was encountered in a 64-year-old man undergoing implantation of a biventricular pacing system. Leads with active fixation were positioned in the right atrium and right ventricle, through the persistent left superior vena cava and the proximal segment of the coronary sinus. For left ventricular pacing, a standard bipolar lead was positioned directly in the posterior branch of the coronary sinus without the use of special guiding catheters.

PAULUSSEN et al. (2004) conducted a case report in Persistent left superior vena cava requiring biventricular pacing (n=1). Implantation of a biventricular pacing system was evaluated. Implantation of a biventricular pacing system was successfully performed in a patient with a persistent left superior vena cava by positioning leads directly through the coronary sinus.
