[Cardiac involvement in central lung cancer].
An x-ray picture of central lung cancer was analyzed in 34 operated patients in whom tumors had infiltrated the myocardium (left atrial infiltration in 33, right atrial infiltration in one, ventricular infiltration in 2). The comparison of x-ray findings with gross specimens of the removed lungs showed that tumor mass consisted of a primary tumor and metastatic bronchopulmonary lymph nodes that made impossible the differentiation of separate elements of the root x-ray image. Angiography was performed in 15 patients with suspected infiltration of the heart by a tumor on the basis of x-ray findings. Cardiac affection which was characterized on x-ray by change in the shape of the chambers, irregularity of their outlines or a filling defect at the site of tumor infiltration. Suspected cardiac infiltration by a tumor can be based on indirect x-ray signs: the presence of a large tumor mass in the area of the root, a shift of the deflated lung regions to the heart, the absence of an image of heart borders and pulmonary veins on tomograms, and a confluent image of the affected lung and cardiac shadow. These signs serve an indication for angiography.
