Key result
Catheter ablation successfully treated atrial flutter in a patient with left ventricular noncompaction, severe mitral regurgitation, and a fasciculo-ventricular accessory pathway.
Case Report (n=1)
No
This is the first reported case of left ventricular noncompaction accompanied by atrial flutter and a Mahaim-type fasciculo-ventricular accessory pathway, successfully treated with catheter ablation.
May support ablation feasibility in LV noncompaction with atrial flutter and fasciculo-ventricular pathway; hypothesis-generating and leaves broader applicability open.
Left ventricular hypertrabeculation/noncompaction (LVHT) is an uncommon type of genetic cardiomyopathy characterized by trabeculations and recesses within the ventricular myocardium. LVHT is associated with diastolic or systolic dysfunction, thromboembolic complications, and arrhythmias, including atrial fibrillation, ventricular arrhythmias, atrioventricular block and Wolff-Parkinson-White syndrome. Herein, we describe a patient who presented with heart failure and wide-complex tachycardia. Echocardiography showed LVHT accompanied with severe mitral regurgitation. The electrophysiologic study revealed a fasciculo-ventricular accessory pathway and atrial flutter (AFL). The AFL was successfully treated with catheter ablation.

Yim et al. (2012) conducted a case report in Left ventricular noncompaction with fasciculo-ventricular accessory pathway and atrial flutter (n=1). Catheter ablation was evaluated on Resolution of atrial flutter. Catheter ablation successfully treated atrial flutter in a patient with left ventricular noncompaction, severe mitral regurgitation, and a fasciculo-ventricular accessory pathway.
