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.
