Abstract:
A 72-year old male, referred for percutaneous atrial fibrillation ablation, was found to have cor triatriatum during routine, pre-procedural transesophageal echocardiography. Accessing the superior pulmonary venous atrium and wide area circumferential ablation was guided by intracardiac echocardiography and performed without complications. The patient remains symptom-free, off anti-arrhythmic drug therapy, for 6 months following ablation. In this report, we emphasize the value of using intracardiac echocardiography during catheter ablation in patients with cor triatriatum.
