An unexpected left atrial cavernous hemangioma: the cardiac surgeon needs an optimal preoperative study!

An optimal preoperative evaluation is fundamental to the assessment of all patients undergoing cardiac surgery.

The tumor was resected via a transatrial approach, and a definitive diagnosis was made after histological examination.
