Acute reduction in pulmonary pressures after lung transplantation for severe chronic pulmonary hypertension may produce a sudden decrease in cavity size of a hypertrophied right ventricle resulting in acquired right ventricular outflow tract obstruction. This case illustrates the utility of transesophageal echocardiography with continuous-wave Doppler to make a morphologic as well as hemodynamic diagnosis of acquired right ventricular outflow tract obstruction in a patient after lung transplantation.
