Massive esophageal hemorrhage after a MitraClip procedure successfully treated by balloon compression.

MitraClip procedure is an effective treatment for mitral regurgitation, performed globally. During the MitraClip procedure, transesophageal echocardiography is an essential modality to perform the operation safely. Although a few transesophageal echocardiography-related complications, such as esophageal hematoma, have been reported, there are no reports on massive esophageal bleeding after the MitraClip procedure. We present the first case of massive esophageal hemorrhage caused by transesophageal echocardiography after a MitraClip procedure and the successful treatment by balloon compression using a Sengstaken-Blakemore tube.
