Treatment of Tachycardia and Bradycardia in a Persistent Left Superior Vena Cava Patient Who Underwent Warden's Procedure and Tricuspid Annuloplasty

ABSTRACT

53-year-old female was admitted to our institution with alternating atrial flutter and junctional bradycardia. The patient had undergone the Warden procedure to correct sinus venosus type atrial septal defect combined with partial anomalous pulmonary venous return, and ring tricuspid annuloplasty for severe tricuspid regurgitation. She also had persistent left superior vena cava (PLSVC). With the assistance of a 3D electroanatomic mapping system, catheter ablation therapy was used successfully to treat atrial flutter associated with a channel in the right atrial scar, and a pacemaker was implanted through the PLSVC because of resulting symptomatic bradycardia.
