Description
João Gabriel Batista Lage and co-authors report a rare heart finding in a 48-year-old man treated for atrial fibrillation. The left atrial appendage, a small pouch in the heart, is where clots most often form in this condition. In this man the pouch was missing from birth, an anomaly with only 23 cases in the medical literature.
During a planned catheter ablation, a scan of the heart suggested a clot where the pouch should be. The team paused, and a CT scan confirmed the pouch had never formed. The ablation then went ahead with radiofrequency energy, and the man later stopped blood thinners by shared decision. He stays free of symptoms and of fibrillation. The case shows why stroke risk scores need care when anatomy is unusual.
