title: We Know What the Cardiac Surgeon Did During Last Hybrid Arrhythmia Procedure.
abstract: Superior vena cava (SVC) is an important source of origin of atrial fibrillation (AF) triggers other than a pulmonary vein. Because of the proximity of SVC-aorta ganglionic plexi to the SVC and the extension of myocardium in the SVC from the right atrium, SVC frequently becomes an important source of ectopic beats initiating AF. The potential complications of SVC isolation may include sinus node injury. Sinus node isolation was observed in a patient who had undergone previous surgical isolation of SVC for AF, while attempting to ablate endocardially, near the superior part of interatrial septum for an atrial tachycardia.
