Abstract
Carney complex is a rare syndrome caused by a genetic mutation leading to multiple endocrine abnormalities and a variety of tumors. Here, we report a case of Carney complex diagnosed due to recurrent multiple myxomas in the right atrium of a patient 16 years after the resection of the primary left atrial myxoma. Surgical excision was performed for the multiple recurrent right atrial tumors under cardiopulmonary bypass. The patient remained complication-free after surgery and was discharged on the 14th day. He was scheduled to continue echocardiographic follow-up and periodic systemic review by an endocrinologist. This case emphasizes the fact that if cardiac myxomas tend to be multiple and recurrent at a relatively young age, the possibility of Carney complex should be considered, even in the absence of any other related feature other than cardiac tumors.
