Abstract
Right atrial appendage aneurysms
(RAAAs) are extremely rare in cardiac anomaly. According to the
literature, no more than 25 cases have been reported so far, among which
only 3 cases were children. Here, we reported an infant with a giant
RAAA and severe symptoms. The RAAA was diagnosed by echocardiography and
surgically resected under cardiopulmonary bypass. The role of
transesophageal echocardiography was very important during the aneurysm
resection surgery, which helped surgeons to plan surgical procedures
during the surgery and evaluate the surgical effect postoperatively.
