Successful epicardial ablation for ventricular tachycardia originating from the true apex of apical aneurysm associated with hypertrophic cardiomyopathy.

Abstract：

:Hypertrophic cardiomyopathy (HCM) with apical aneurysm (AA) is rare, but has been reported to be associated with refractory ventricular tachycardias (VTs). Majority of such cases had a central isthmus of the reentry circuit on the border zone of AA. In this report, we describe a rare case of the successful epicardial ablation for a refractory VT originating from a true apex of the aneurysm in a HCM patient. Mid-diastolic potential during sustained VT was recorded at the isolated epicardial myocardium surround by the gross unexcitable scar in AA, and radiofrequency current application rendered VT non-inducible.
