Congenital long QT syndrome treated by renal sympathetic denervation

In this case, we treated a 14-year-old congenital long QT syndrome patient with renal sympathetic denervation for the first time. In four positive sites, renal nerve stimulation-induced frequent multiform premature ventricular beats (PVCs) the same morphologies as preoperation (Figure, denoted by asterisks), implying renal nerves on these specific sites exactly participated in the pathogenesis of ventricular arrhythmias. After ablation, no PVCs could be induced anymore. The patient was free of syncope during the follow-up of 5 months up to now, with the QT interval got significantly shortened from 600 ms before ablation to 500 ms post-ablation, and no ventricular arrhythmia was observed in two consecutive Holter monitor.
