Catheter ablation of pulmonary sinus cusp-derived ventricular arrhythmias by the reversed U-curve technique.

An editorial is presented on the treatment of ventricular arrhythmias (VA) that are derived from pulmonary sinus cusp (PSC) which uses radiofrequency catheter ablation (RFCA) through the application of reversed U curve technique. Topics mentioned the retrospective analysis on patients with VA, the comparison of the technique with the conventional technique, and the suggestion to consider ablation and mapping when electrocardiography (ECG) shows the VA characteristics.
