Post-prandial high-grade atrioventricular block after gastric sleeve surgery: a case report

Weight loss after bariatric surgery is associated with improved long-term cardiovascular outcomes. However, available data suggests a relationship between bariatric surgery and cardiac bradyarrhythmias. In our case, we report recurrent episodes of syncope due to high-grade AVB after gastric sleeve surgery, treated by permanent pacemaker implantation. To our knowledge, this complication has not been previously reported, and this case highlights the need for further studies to explore the relationship between bariatric surgery and cardiac arrhythmias and to prevent potential complications.
