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

Symptomatic supraventricular tachycardia is a common indication for radiofrequency catheter ablation treatment. Often, supraventricular tachycardia is associated with sick sinus syndrome, which requires the implantation of a permanent pacemaker.

We report a case of tachycardia and bradycardia that was complicated by several congenital cardiac anomalies and a prior cardiac surgery, and that was treated successfully. Case
