Compression of the Pulmonary Artery During Transesophageal Echocardiography in a Pediatric Cardiac Patient

Abstract

Hemodynamic compromise caused by the insertion of the probe for transesophageal echocardiography in a patient with severe stenosis of the main pulmonary artery is reported for the first time. The first symptom of the impending problem was a rapid decrease of end-tidal CO(2).
