title: Fluoroscopically guided transesophageal echocardiogram in a patient with esophageal stents.
abstract: A 73-year-old man with history of coronary artery disease and bypass surgery, atrial fibrillation, and left lower lobe non-small cell lung cancer was admitted with recurrent pneumonia and was referred for transesophageal echocardiogram for suspected aortic valve endocarditis by transthoracic echocardiography. The patient had a history of radiation treatment for lung cancer 6 years ago. He had subsequently developed esophageal strictures requiring repeated dilatations, and eventually repeated esophageal stenting. Recurrent aspiration pneumonia led to the discovery of stent erosion into his trachea leading to tracheoesophageal fistula. A covered Y tracheal stent was placed to close the fistulous tract, but persistent aspiration was noted. The cross-sectional diameter of the esophageal stents was determined to be larger than the transesophageal echocardiography (TEE) probe. TEE was performed under fluoroscopy for added safety. The esophageal stent position was confirmed with fluoroscopy before and after the procedure and the TEE probe remained inside the distal stent in the midesophageal position during the entire procedure. Small mobile vegetation was seen on the right coronary cusp and the noncoronary cusp showed a smaller vegetation. The patient tolerated the procedure well and there were no complications. Infectious disease consultation was obtained and antibiotic regimen was modified accordingly. Although there are studies addressing the safety of TEE in patients with esophageal varices, to our knowledge, there is no report of TEE being performed in patients with esophageal or tracheoesophageal stents. This case illustrates that TEE may be performed in patients with esophageal stents under careful fluoroscopic guidance. (Echocardiography 2012;29:E5-E7).
