Wann Aditya Bhonsale Krishna Kancharla Andrew Voigt Sandeep Jain Mark Estes Samir Saba Konstantinos N. Aronis Journal of Cardiovascular Electrophysiology ABSTRACT Background Bipolar radiofrequency ablation has been increasingly used in cases with deep intramyocardial circuits refractory to unipolar ablation. Patients with Lamin A/C cardiomyopathy frequently exhibit VT arrhythmia originating from deep in the interventricular septum. Methods and Results We describe our use of bipolar ablation in a patient with nonischemic cardiomyopathy and Lamin A/C mutation for the treatment of a septal VT substrate with particular attention to pathology findings at 3 months. Conclusions Bipolar ablation with catheters across the septum and in the presence of a microcatheter in a septal branch of the anterior interventricular vein was effective in controlling ventricular arrhythmia. Resultant ablation resulted in extensive myocardial injury and fibrosis. Neointimal hyperplasia of intervening coronary arteries may play a role in subsequent effects of initial ablation lesions. 10.1111/jce.16721 http://creativecommons.org/licenses/by-nc-nd/4.0/ |
