Abstract
Isolation of Critical Site in Arrhythmogenic RV Cardiomyopathy. We describe a patient with arrhythmogenic right ventricular cardiomyopathy in whom ventricular tachycardia (VT) was ablated by isolating a relatively large area of the critical site using catheter ablation. Endocardial mapping showed abnormal fragmented electrograms with delayed potential (DP) from an entire area of the aneurysm. Pace mappings from the aneurysm produced a QRS morphology identical to that of clinical VT. After catheter ablation was performed at the exit site of the VT critical area, programmed stimulation inside the aneurysm captured the DP but not the QRS complexes. These data suggest that VT can be ablated successfully by isolation of the critical area.
