Abstract:
Atrial pseudoaneurysms are exceedingly rare. Cardiac pseudoaneurysms are at risk for rupture, which may be catastrophic and require emergent thoracotomy for definitive treatment. We report a case of right atrial appendage perforation during catheter ablation leading to tamponade and right atrium pseudoaneurysm.
