Cardiac Sympathetic Denervation for Prevention of Ventricular Tachyarrhythmias

Cardiac sympathetic denervation is performed using an endoscopic procedure called VATS (video-assisted thoracoscopic sympathectomy). The surgeon removes the lower half of the stellate ganglia in addition to the thoracic ganglia of T2 - T4 on both the right and left side. The VATS procedure provides a minimally invasive endoscopic approach that is safe and effective. The procedure can be completed in less than 45 minutes on each side.

Anti-arrhythmic medications are continued for the duration of the study unless discontinued or adjusted to due to drug toxicity, intolerance, or ICD shock. All anti-arrhythmic medications (whether in the routine care or surgical arm) can be adjusted at the discretion of the treating physician.
