Combined Endocardial and Epicardial Ablation of Drug-Refractory
Ventricular Tachycardia by Direct Ventricular Puncture
Abstract
Mechanical valves in both aortic and mitral positions pose a challenge
for left ventricular (LV) access during ventricular tachycardia (VT)
ablation using the antegrade transseptal or the retrograde transaortic
approach. A 57 year-old male with ischemic cardiomyopathy, mechanical
aortic and mitral valves, and recurrent VT underwent a combined
endocardial and epicardial ablation via direct ventricular puncture via
mini-thoracotomy. Successful mapping with endocardial and epicardial
ablation was performed, with no recurrent VT on follow up. We showcase
the feasibility of VT ablation using an open transapical approach for
patients with mechanical aortic and mitral valves.
