Abstract

|
A patient presented with loss of consciousness and conversion. During an exercise test, catecholaminergic polymorphic ventricular tachycardia (CPVT) resulted in cardiac arrest. He started taking medication (a beta-blocker and flecainide) and an implantable cardioverter defibrillator (ICD) was inserted, but the ventricular tachycardia did not resolve. Left cardiac sympathetic denervation (LCSD) was then performed under general anesthesia, and the patient was discharged on the second postoperative day without complications. One month after the operation, no shock had been administered by the ICD, and an exercise stress test did not induce ventricular tachycardia. Although beta-blockers are the gold standard of therapy in patients with CPVT, thoracoscopic LCSD is safe and can be an effective alternative treatment option for patients with intractable CPVT.
