Abstract

Arrhythmias from the right and left ventricular outflow tract may stem from supravalvular myocardial extensions. Medical therapy has traditionally been unsuccessful, so in symptomatic cases or those in which arrhythmia-induced cardiomyopathy develop we should opt for an intervention. Mapping and use of radiofrequency energy has to be performed above semilunar valves for their successful elimination by ablation, in the regions that have specific anatomical features. This review article provides a brief overview of the anatomical substrate of these arrhythmias and intraprocedural steps that lead to successful and safe ablation, as well as an overview of our own experience.

Keywords
