Upper gastrointestinal injury associated with cryoablation and under placement of transesophageal echocardiography (TEE) during cardiac surgery is a rare complication but potentially fatal. During the cryoablation for the treatment of atrial fibrillation, delivered cryoenergy can adversely affect the esophagus, resulting in gastroesophageal ulceration. The TEE probe itself also can induce adverse effects like esophageal ulceration or perforation. In this case report, we describe a case of emergent gastroesophageal injury with massive bleeding that occurred after manipulation of a TEE probe during cryoablation therapy in a cardiac surgery patient.
