Atresia of the Coronary Sinus Ostium to the Right Atrium with a Persistent Left Superior Vena Cava

The coronary sinus has lately assumed an important role in the cardiologic clinic once it has been widely used in invasive procedures of the heart. Commonly, it is used during the electrodes implants for the epimiocardic monitoring of the cardiac rhythm, through a biventricular pace maker. These inv...
