Key result
Percutaneous epicardial radiofrequency ablation at the lateral mitral annulus successfully treated sustained monomorphic ventricular tachycardia and normalized right ventricular ejection fraction.
Case Report (n=1)
Ventricular tachycardias originating from the left ventricular epicardium can mimic right ventricular outflow tract VT or ARVC and induce isolated, reversible right ventricular dysfunction.
No takes yet. Share an insight, caveat, or question.
May warrant considering epicardial LV origin in VT with isolated RV dysfunction; hypothesis-generating, requires prospective confirmation.
Massoure et al. (2009) conducted a case report in Sustained monomorphic ventricular tachycardia (n=1). Percutaneous epicardial radiofrequency ablation was evaluated on Ablation success and normalization of right ventricular ejection fraction. Percutaneous epicardial radiofrequency ablation at the lateral mitral annulus successfully treated sustained monomorphic ventricular tachycardia and normalized right ventricular ejection fraction.
