Key result
Surgical resection of a giant right atrial diverticulum in a 32-year-old man revealed extreme wall thinning and aneurysmal formation consistent with idiopathic dilatation of the right atrium.
Case Report (n=1)
Surgical resection of large right atrial diverticula is recommended to reduce the risk of sudden death, despite unclear risks of thromboembolism, arrhythmia, and rupture.

Documents extreme thinning in giant right atrial diverticulum; leaves open optimal management and complication risks.
We describe a 32-year-old man with chest pain and a giant right atrial diverticulum who underwent surgical resection. Examination of resected atrial tissue showed extreme wall thinning, central aneurysmal formation, and focal endocardial fibrosis consistent with idiopathic dilatation of the right atrium. It is unclear what the best treatment of right atrial diverticulum are, nor are the risks of thromboembolism, arrhythmia, and rupture of the diverticulum clearly defined, either for patients as a whole or for symptomatic or asymptomatic subgroups. However, to reduce the risk of sudden death we recommend surgical resection of large diverticula.
