title: Reversible pulmonary artery obstruction in a patient with bronchogenic carcinoma. Diagnosis by two-dimensional and Doppler echocardiography.
abstract: Neoplastic invasion of the pulmonary arteries, although common, rarely results in obstruction to right ventricular outflow. We report an unusual case of severe pulmonary hypertension, right ventricular dilatation, and righ ventricular dysfunction resulting from pulmonary arterial compression by bronchogenic carcinoma. The diagnosis was made by two-dimensional and Doppler echocardiography and supported by computed tomographic findings. Echocardiography was used to follow the patient's response to therapy and documented the subsequent resolution of pulmonary arterial obstruction.
