Catheter ablation using intracardiac echocardiography integrated with 3D electroanatomical mapping successfully eliminated intramural PVCs with no arrhythmia recurrences during follow-up.

Does ICE-guided catheter ablation prevent arrhythmia recurrence in a patient with intramural PVCs originating from the posterior superior process of the left ventricle?
Intracardiac echocardiography integrated with 3D mapping is a valuable tool for successfully targeting and ablating challenging intramural PVCs originating from the posterior superior process of the left ventricle.
Intramural premature ventricular complexes (PVCs) are notoriously challenging during catheter ablation due to the depth of the arrhythmogenic substrate. We present a case utilizing intracardiac echocardiography (ICE) integrated with 3D electroanatomical mapping to ablate an intramural PVC in a patient with methamphetamine-associated cardiomyopathy. A 22-year-old female with a history of stimulant use disorder presented with debilitating palpitations and a 46% PVC burden. PVCs originating from the posterior superior process of the left ventricle (PSP-LV) were successfully targeted under ICE guidance. There were no arrhythmia recurrences during follow-up, highlighting ICE as an invaluable tool for mapping and ablating PSP-LV origin PVCs.
Perumalu et al. (Mon,) conducted a case report in Intramural premature ventricular complexes (PVCs) and methamphetamine-associated cardiomyopathy (n=1). Intracardiac echocardiography (ICE) integrated with 3D electroanatomical mapping for PVC ablation was evaluated on Arrhythmia recurrences during follow-up. Catheter ablation using intracardiac echocardiography integrated with 3D electroanatomical mapping successfully eliminated intramural PVCs with no arrhythmia recurrences during follow-up.
