Abstract:
A patient with a remitting non-microcytic pulmonary carcinoma was subjected to Doppler-echocardiography. The detection of a pericardial effusion with compression of the pulmonary artery due to an extrinsic mass indicated that the disease was progressing. The Doppler technique was used to evaluate the degree of arterial stenosis by determining the pressure gradient caused by it (49 mmHg) and to calculate the right ventricle pressure (75 mmHg). Tumor infiltration of mediastinal structures was posteriorly confirmed by computed tomography.
