Resynchronization Therapy in a Coronary Venous Sinus Anomaly.

ABSTRACT:

Anatomy

Coronary venous sinus is the major portal for cardiac venous drainage and plays a crucial role in electrophysiological procedures like left ventricular pacing.

Pathology

Although congenital anomalies of the coronary sinus are rare, we present a unique case of interrupted coronary sinus. The proximal segment drained normally into the right atrium, while the distal segment drained into a common channel that connected to the left subclavian vein via a persistent left superior vena cava.

Imaging correlation

This anomaly was initially suspected during Levo-phase coronary sinus angiography and further confirmed by computed tomography and direct coronary sinus angiography.

Treatment

The patient successfully underwent implantation of a cardiac resynchronization
