Supports ICE-guided ablation feasibility in cor triatriatum with refractory AF; leaves open generalizability beyond this case.
Cor triatriatum is a rare congenital cardiac anomaly that is characterized by a thin membrane separating the left atrium both functionally and anatomically. Patients with cor triatriatum are at risk for atrial arrhythmias, which can be especially symptomatic owing to a functional mitral stenosis physiology. We present a case of a patient with cor triatriatum and drug-refractory atrial fibrillation (AF) and atrial flutter (AFl) requiring imaging-guided ablation in both partitions of the left atrium.

Borne et al. (2016) conducted a case report in Cor triatriatum with atrial fibrillation and atrial flutter (n=1). Catheter ablation guided by intracardiac echocardiography was evaluated on Arrhythmia recurrence. Intracardiac echocardiography-guided catheter ablation successfully treated drug-refractory atrial fibrillation and atrial flutter in both partitions of the left atrium in a patient with cor triatriatum, with no recurrence at over 1 year.
