Unilateral pulmonary edema during transesophageal echocardiography

Transesophageal echocardiography is considered to be a relatively safe procedure, the complications of which are well known and include probe- related and procedure-related complications. Congestive heart failure rarely occurs. Unilateral pulmonary edema is relatively uncommon and to the best of our knowledge has never been reported in association with transesophageal echocardiography. Herein we describe an unusual case of unilateral pulmonary edema that developed during the course of transesophageal echocardiography.
