TL;DR: Catheter ablation of VT in patients with structural heart disease results in 70% freedom from VT recurrence, with an overall transplant and/or mortality rate of 15% at 1 year, which is associated with improved transplant-free survival, independent of heart failure severity.
Journal ArticleDOI
The Role of the Autonomic Nervous System in Sudden Cardiac Death
TL;DR: The anatomy of both systems, the sympathetic and the parasympathetic systems, are described, which are complex and susceptible to control at several levels, from centrally mediated baroreceptors and chemoreceptors to local interneuronal interactions.
Journal ArticleDOI
Cardiac sympathetic denervation in patients with refractory ventricular arrhythmias or electrical storm: Intermediate and long-term follow-up
Marmar Vaseghi,Jean Gima,Christopher Kanaan,Olujimi A. Ajijola,Alexander Marmureanu,Aman Mahajan,Kalyanam Shivkumar +6 more
TL;DR: The beneficial effects of bilateral CSD extend beyond the acute postsympathectomy period, with continued freedom from ICD shocks in 48% of patients and a significant reduction in ICDshocks during follow-up compared to the 12 months before.
Journal ArticleDOI
Neuraxial Modulation for Refractory Ventricular Arrhythmias: Value of Thoracic Epidural Anesthesia and Surgical Left Cardiac Sympathetic Denervation
Tara Bourke,Marmar Vaseghi,Yoav Michowitz,Vineet Sankhla,Mandar Shah,Nalla Swapna,Noel G. Boyle,Aman Mahajan,Calambur Narasimhan,Yash Lokhandwala,Kalyanam Shivkumar +10 more
TL;DR: It is suggested that TEA and LCSD may be effective additions to the management of refractory ventricular arrhythmias in structural heart disease when other treatment modalities have failed or may serve as a bridge to more definitive therapy.
Journal ArticleDOI
Characterization of the arrhythmogenic substrate in ischemic and nonischemic cardiomyopathy implications for catheter ablation of hemodynamically unstable ventricular tachycardia.

TL;DR: An approach incorporating LP ablation and pace-mapping had limited success in patients with NICM compared with ICM, and alternative ablation strategies should be considered.
