RT Journal Article SR Electronic T1 Lessons of the month 1: Fatal oesophago-pericardial fistula with cerebral air embolism after elective atrial fibrillation ablation JF Clinical Medicine JO Clin Med FD Royal College of Physicians SP 331 OP 333 DO 10.7861/clinmedicine.19-4-331 VO 19 IS 4 A1 Jonathan Dutton A1 Marco Morosin A1 Rita Fernandez-Garda A1 Vladamir Anikin A1 Ana Hurtado-Doce A1 Nicholas Lees YR 2019 UL http://www.rcpjournals.org/content/19/4/331.abstract AB Oesophago-pericardial fistula following any electrophysiological procedure is a rare, and potentially, life-threatening condition. Initial presentation can easily be misdiagnosed, as symptoms vary and are not specific. Echocardiography is an invaluable tool to diagnose and rule out complications. We present the case of a 68-year-old patient who developed an oesophago-pericardial fistula complicated with purulent pericarditis, sepsis and cerebral air embolism. In conclusion, this case report encourages physicians to use strategies that may help with early diagnosis and lead to potential lifesaving interventions.
