Buffalo Surgeons Perform Selective Cardiac Denervation to Reduce the Likelihood of Postoperative Arrhythmias

Up to one third of patients develop atrial arrhythmias after heart surgery, the most common type being atrial fibrillation. A surgeon at the Buffalo General Hospital has been routinely performing selective cardiac denervation to reduce the likelihood of developing this arrhythmia. Atrial fibrillation after coronary bypass surgery prolongs hosptialization and necessitates administering an anticoagulant which the patient may need to take for at least 3 months and sometimes forever.

Selective cardiac denervation takes an additional 5 minutes and involves resecting sympathetic nerve fibers between the aorta and the pulmonary artery. The procedure is done before initiating cardiopulmonary bypass and has reduced the incidence of atrial fibrillation in a prospective nonrandomized pilot study from 35% to 11%.

Dr. Karamanoukian has analyzed his study results and plans on performing it in all of his patients undergoing bypass surgery and is in the process of submitting these exciting and important results in a peer reviewed journal.
