Acute Delayed Gastric Emptying after Ablation of Atrial Fibrillation: Treatment with Botulinum Toxin Injection

Abstract

Percutaneous transcatheter radiofrequency (RF) ablation of pulmonary veins is increasingly used for the treatment of refractory atrial fibrillation. With this technique, lesions are created around the ostia of each pulmonary vein to electrically isolate them from the left atrium [1]. We report a case of acute pyloric spasm after RF ablation, which improved after intrapyloric botulinum toxin injection.
