Abstract:
We report a case of left atrial extrinsic compression caused by an esophageal food bolus in a patient presenting with acute heart failure. Transthoracic echocardiography along with contrast-enhanced CT showed evidence of esophageal dilation producing left atrial compression. Esophageal endoscopy and fragmentation of the bolus, allowing the accumulated food to descend into the stomach, produced a rapid improvement of hemodynamic and clinical status. © 2017 Wiley Periodicals, Inc.
