A very rare cardiac hibernoma in the right atrium: a case report

Cardiac lipomas are rare tumors often detected incidentally during routine examinations. They usually remain asymptomatic for a long time and cause arrhythmia, heart valve dysfunction, or embolization in the later stages. In this article, we report a case of a 64-year-old patient with a very rare cardiac hibernoma located in the right atrium. Transesophageal echocardiography and computed tomography have been shown to be useful for differentiating between benign and malignant tumors in order to plan surgery. The treatment of choice for these tumors is resection. The tumor was excised with the use of cardiopulmonary bypass surgery. Histology confirmed diagnosis of a benign cardiac hibernoma.
