Idioventricular Rhythm: A Rare Presentation of Left Ventricular Pseudoaneurysm Following Radiofrequency Ablation

Cureus. 2024 Feb 29;16(2):e55272. doi: 10.7759/cureus.55272. eCollection 2024 Feb.

Abstract

Left ventricular pseudoaneurysm (PsA) is a rare complication of radiofrequency ablation (RFA) of cardiac arrhythmias. Presentation can vary widely in terms of timeline, signs, and symptoms. Idioventricular rhythm is a rare presentation of PsA post-ablation. No cases of post-ablation PsA presenting with idioventricular rhythm have been reported in the literature to date. A 72-year-old male presented with symptomatic idioventricular rhythm 34 days post RFA for premature ventricular complexes (PVCs). A PsA involving the distal anterolateral of his left ventricle wall was identified on transthoracic echo and computed tomography (CT). This patient underwent surgical patch repair which resolved his ventricular arrhythmia.

Keywords: idioventricular rhythm; left ventricular pseudoaneurysm; premature ventricular complexes; radiofrequency ablation (rfa); ventricular arrhythmias.
