Intracoronary mapping followed by intramyocardial ablation using radiofrequency (RF) ablation delivered through a system routinely used to treat coronary artery chronic total occlusions is feasible and effective. Unlike alcohol injection and coil embolization of septal perforator arteries, intramyocardial RF ablation using this technique is a more localized and limited approach that carries less risk of complete atrioventricular block and myocardial injury.
