Right Ventricular Epicardial Pacing Postcardiac Surgery Can Cause Dynamic Right Ventricular Outflow Tract Obstruction: A Case Report

We describe 2 cases of dynamic right ventricular outflow tract obstruction that developed immediately after separation from cardiopulmonary bypass, due to temporary right ventricular epicardial pacing. Both patients had systemic hypotension which improved once ventricular pacing was discontinued. We discuss the recognition of right ventricular outflow tract obstruction as a contributing factor to hemodynamic instability, as well as the importance of identifying the underlying cause such as to institute appropriate management in these patients.
