Arrhythmic risk profile and outcomes of patients undergoing cardiac sympathetic denervation for recurrent monomorphic ventricular tachycardia after ablation
Journal of the American Heart Association Jan 18, 2021
Dusi V, Gornbein J, Do DH, et al. - Researchers sought to quantify arrhythmia recurrence risk as well as the influence of cardiac sympathetic denervation (CSD) among patients with scar‐related monomorphic ventricular tachycardia (VT) referred for VT ablation and then CSD. Patients with any evidence of polymorphic VT were eliminated. They studied data from 381 patients who had VT ablation. CSD for recurrent VT was received by 68 patients. Experts found that a higher risk of VT recurrence post-ablation was present in patients referred for CSD for refractory scar‐mediated monomorphic VT, vs those not needing CSD, mostly due to their cardiac comorbidities. A significant decrease in both the expected risk of recurrences and VT burden was conferred by CSD.
