Left cardiac sympathetic denervation in the management of long QT syndrome and catecholaminergic polymorphic ventricular tachycardia: A meta-regression.

LCSD was associated with a reduction in the incidence of CEs in LQTS, CPVT patients and in the duration of QTc. Open surgery was associated with a greater reduction in QTc. Due to the limitations that hindered our study, a randomized trial is warranted to fully establish LCSD safety and efficacy.
