Outcomes of Cardiac Sympathetic Denervation via Cautery Ablation for Ventricular Arrhythmia: A Single Center Study

摘要: Introduction: Cardiac sympathectomy denervation (CSD) has been demonstrated to reduce ventricular arrhythmia (VA) burden and to improve arrhythmia-free survival. Early evidence for the clinical antiarrhythmic benefits for CSD was established in patients with long-QT syndrome and catecholaminergic polymorphic VT (CPVT). Its benefit has subsequently been shown to extend to other undifferentiated cardiomyopathies. Hypothesis: Literature on CSD for VA has been limited due to a small number of patients. Our retrospective study is to review patients who underwent CSD for VA at our center via cautery ablation. Methods: We identified 9 patients who underwent CSD from 4/2018 to 2/2022. Electronic medical record was reviewed for clinical history and outcomes. Results: Mean age was 52±17 and 5 patients (55.6%) were male. Seven patients (77.8%) had nonischemic cardiomyopathy (NICM) and 2 patients (22 …
