Does thoracoscopic left cardiac sympathetic denervation prevent recurrent ventricular tachycardia and ICD shocks in a patient with intractable CPVT?
Thoracoscopic left cardiac sympathetic denervation may be a safe and effective alternative treatment for patients with intractable CPVT experiencing recurrent ICD shocks despite optimal medical therapy.
May be considered for refractory CPVT with recurrent shocks; single case leaves open need for prospective validation.
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.

Yu et al. (2015) conducted a case report in Catecholaminergic polymorphic ventricular tachycardia (n=1). Thoracoscopic left cardiac sympathetic denervation was evaluated on Recurrence of ventricular tachycardia or ICD shocks. Thoracoscopic left cardiac sympathetic denervation successfully prevented recurrent ventricular tachycardia and ICD shocks at one-month follow-up in a patient with intractable CPVT.
