Left Cardiac Sympathetic Denervation in Long QT Syndrome

Abstract

Although a marked reduction in number of cardiac events is usually seen after LCSD, ≈50% of high-risk LQTS patients have experienced ≥1 post-LCSD breakthrough. Therefore, LCSD must not be viewed as curative or as an alternative in implantable cardioverter defibrillator for high-risk patients. Prophylactic LCSD may provide another option to counter a suboptimal quality of life resulting from medication-related side effects.
