Angoff RK, Waks JW, Gavin MC, Stabenau HF, Strom JB. A Focus on the Right Atrium: Right Atrial Diverticulum and Atrial Flutter. JACC. Case reports. 2023;11:101788.
We report a case of a 70-year-old woman who presented for a cavotricuspid isthmus atrial flutter ablation that was aborted prematurely. On subsequent imaging, she was discovered to have a right atrial diverticulum, which was present on prior imaging but not reported, likely due to unfamiliarity with the entity. (Level of Difficulty: Intermediate.).
