Abstract
|
|
|
|
A 40-year-old female patient was referred for ablation of recurrent episodes of supraventricular tachycardia. Echocardiography revealed a persistent left superior vena cava (PLSVC). Cardiac electrophysiology study revealed typical atrioventricular nodal reentry tachycardia (AVNRT). Coronary sinus (CS) catheter was introduced through the PLSVC from the left subclavian vein. The other catheters were introduced through the right superior vena cava and the azygos vein from the femoral vein because the inferior vena cava (IVC) was interrupted. Thus, in a patient with an interrupted IVC with azygos continuation and a PLSVC, we performed a successful catheter ablation of AVNRT with conventional fluoroscopy guidance at the anterior portion of the proximal coronary sinus.
