Late development of left ventricular (LV) pseudoaneurysms after ventricular tachycardia (VT) catheter ablation is a rare phenomenon, and very few cases have been reported in the medical literature. We describe the case of a giant LV pseudoaneurysm as a late complication of multiple epicardial and endocardial VT ablations in a female in her 50s with known cardiac sarcoidosis.
