Risk of dysphagia after transesophageal echocardiography
Mitral Valve Insufficiency
Transesophageal echocardiography (TEE) allows evaluation of cardiac, valvular and vascular structure and function in a relatively noninvasive manner. Although sustained esophageal pressure during intraoperative monitoring might possibly cause injury to the mucosa or deeper layers, reports of complications related to the technique are rare. Cucciara et al1 reported laryngeal injury after TEE monitoring in the sitting position. Urbanowicz et al2 found no histologic esophageal damage in dogs after maximum surface contact pressure between the esophagus and a fully flexed TEE probe. After several patients complained of dysphagia after cardiac surgery, we identified by prospective interviews 20 patients who had dysphagia postoperatively. © 1991.
