Abstract

Gastropericardial fistula is a significantly rare and life-threatening condition. Here we present a 55-year-old female with current tobacco use and prior open gastric bypass with known gastrogastric fistula and recurrent marginal ulcers. She presented in cardiac tamponade with a large, loculated hydropneumopericardium and pericardial fistula identified on CT imaging.

Her post-operative course was unremarkable and she was discharged on post-operative day seven. Follow-up within our health system is currently 2.5 years.
