[Stenosis of the right pulmonary artery secondary to carcinoma of the left lung. Effect of radiation therapy (author's transl)].
A case of undifferenciated carcinoma of the left lung with stenosis of the right pulmonary artery is reported. The characteristic clinical features of the systolic ejection murmur in pulmonary artery stenosis are recalled as well as the data from phonocardiographic, angiographic, and hemodynamic investigations. After radiation therapy, the grade of the systolic murmur decreased frankly although transiently. Noticeable decrease of the stenosis was substantiated by a second angiography. This improvement was still apparent 16 months later during chemotherapy.
