Right Ventricle Systolic Dysfunction: A Rare Cause of Right-To-Left Interatrial Shunt with Normal Pulmonary Artery Pressure

There is little information about right-to-left shunting with normal pulmonary artery pressure, which is produced as a consequence of right ventricle systolic dysfunction. We presented a case of unexpected transesophageal echocardiography findings of right-to-left shunting through an atrial septal defect despite normal pulmonary artery pressure, related to right ventricle systolic dysfunction in a 27-year-old young woman. Transesophageal echocardiography imaging revealed right ventricular systolic dysfunction and normal pulmonary artery pressure.
