Superior Mesenteric Artery Syndrome Resulting From Gastric Dilatation After Catheter Ablation of Atrial Fibrillation.

Abstract

Catheter ablation (CA) is a recognized treatment for people experiencing symptomatic paroxysmal or persistent atrial fibrillation (AF). Pulmonary vein isolation (PVI) is the predominant therapeutic intervention for AF globally. According to PVI, some individuals may require supplementary ablation interventions. Literature has shown that the closeness of the esophagus to the posterior wall of the left atrium might result in injury to the vagal nerve branches during CA, causing conditions such as "gastroparesis" or "pyloric spasms." This report details a case of superior mesenteric artery compression syndrome following AF ablation, which did not improve with conservative management and was ultimately addressed by surgical procedure.
