PULMONARY ARTERY STENOSIS

Pulmonary artery stenosis.

SINCE the description by Mbller' in 1953 of stenosis of peripheral pulmonary arteries, this congenital lesion has been recognized with increasing frequency. The lesion is of interest both from a clinical and physiologic standpoint. From the latter standpoint, there is sufficient documentation to warrant the inclusion of this congenital anomaly as one of the causes of right ventricular hypertens...

Acquired pulmonary stenosis and pulmonary artery compression.

Echocardiographic appearance of pulmonary artery stenosis.

Colour flow Doppler mapping can show abnormalities of flow even when the echocardiographic image is equivocal. Routine echocardiography in two patients who were thought to have pulmonary valve stenosis and a ventricular septal defect initially appeared to be normal. Colour flow Doppler mapping, however, showed multiple flow aliasing within the pulmonary artery, approximately 1.5 cm downstream f...

Congenital Stenosis of the Pulmonary Artery Branches.

CONGENITAL stenosis of the pulmonary artery branches is an anomaly characterized by narrowed segments of one or more of the main or peripheral branches of the pulmonary artery. Such conditions lhave been variously labeled pulmonary coaretation,' peripheral pulmonary stenosis,2 and multiple peripheral stenoses 3 of the pulmonary artery. Several cases of this anomaly have appeared in the literatu...

Postvalvular stenosis of the pulmonary artery.

RECENT reports have focused attention on the occasional occurrence of localized constrictions in the pulmonary vascular system distal to the valve of the pulmonary artery. Such lesions have been called "coarctation of the pulmonary artery."'-3 We believe the less specific term "postvalvular stenosis" to be somewhat more inclusive and more descriptive of these defects. Schumacher and Lurie4 have...
