Sinus Node Artery Occlusion During Cardiac Denervation Procedures

Cardioneural ablation is a novel treatment for functional bradycardia. However, the risk of acute complications is still unknown. The aim of this case report is to describe acute occlusion of the sinus node artery after cardiac denervation procedures in 2 patients and to encourage measures to prevent it, such as evaluating the aortic angulation in older patients before the procedure and by monitoring signs of sinus failure during ablation in patients with electroanatomical maps showing a constricted aspect of the right atrium.
