Right atrial appendage aneurysms (RAAAs) are extremely rare in cardiac anomalies. According to the literature, a few dozen cases have been reported thus far, among which only four cases were infants or neonates. Here, we report an infant with a giant RAAA and severe symptoms. The RAAA was diagnosed by echocardiography and surgically resected under cardiopulmonary bypass (CPB). The role of transesophageal echocardiography was very important during aneurysm resection surgery, which helped surgeons to plan surgical procedures during surgery and evaluate the surgical effect postoperatively.
Keywords: echocardiography; giant; infant; right atrial appendage aneurysms.
