Radiofrequency catheter ablation is a treatment option for medically refractory ventricular arrhythmias in arrhythmogenic right ventricular dysplasia, with variable acute and long-term success rates.
Does radiofrequency catheter ablation reduce recurrent ventricular tachycardias in patients with arrhythmogenic right ventricular dysplasia?
Radiofrequency catheter ablation is a viable treatment option for medically refractory ventricular arrhythmias in patients with arrhythmogenic right ventricular dysplasia.
Arrhythmogenic right ventricular dysplasia (ARVD) is a genetically determined myocardial disease characterized by fibrofatty replacement of the right ventricular wall. Ventricular tachyarrhythmias can be seen in the early stages of the disease, which is one of the most important causes of sudden death in young healthy individuals. Radiofrequency (RF) catheter ablation is an option for the treatment of medically refractory ventricular arrhythmias and it has shown to successfully abolish recurrent ventricular tachycardias (VT) as well as reduce the frequency in defibrillator therapies. However, variable acute and long-term success rates have been reported. The current mapping and ablation techniques include activation and entrainment mapping during tolerated VT and substrate ablation using 3-dimensional electroanatomic mapping systems. This article aims at providing a comprehensive review of RF catheter ablation of ventricular arrhythmias in the context of ARVD.
Arbelo et al. (Mon,) conducted a review in Arrhythmogenic right ventricular dysplasia (ARVD) with ventricular arrhythmias. Radiofrequency (RF) catheter ablation was evaluated. Radiofrequency catheter ablation is a treatment option for medically refractory ventricular arrhythmias in arrhythmogenic right ventricular dysplasia, with variable acute and long-term success rates.
