Abstract

Abstract: Background: Recurrent ventricular tachycardia (VT) can occur after left ventricular assist device (LVAD) implantation. In this case, medical treatment might be insufficient. We report a case of a left‐sided thoracoscopic sympathectomy as a feasible treatment escalation in intractable VT. Case Report: A 72‐year‐old patient underwent an internal cardioverter defibrillator (ICD) implantation as primary prophylaxis for VTs in the setting of staged heart failure therapy. Afterwards, due to a progressive dilative cardiomyopathy he underwent a minimal‐invasive LVAD implantation (HeartWare, Medtronic). After an uneventful minimal‐invasive LVAD‐implantation the patient was discharged to a rehabilitation program. However, after 7 weeks he developed recurrent VTs which were successfully terminated by ICD shocks deliveries leading to severe discomfort and frequent hospitalizations. Eventually, the patient was admitted with an electrical VT storm. Successful endocardial catheter ablation of all inducible VTs were performed combined with multiple rearrangements of his oral antiarrhythmic medication. However, all these treatments could not suppress further occurrence of VTs. After an interdisciplinary discussion the patient agreed to a left‐sided video‐assisted thoracoscopic sympathectomy. After a follow up of 150 days the patient was free from VTs apart from one short event. Conclusion: We believe video‐assisted thoracoscopic sympathectomy might be a surgical treatment option in patients with intractable recurrent VTs after catheter ablation of VT reentrant substrate even after minimal‐invasive LVAD implantation.
