Massive Occlusion of the Main Pulmonary Artery and Its Primary Branches with Subsequent Cor Pulmonale

Massive occlusion of the main pulmonary artery and primary branches; case report.

[ASSIVE occlusion of the main pulmonary artery and its primary branches is believed seldom compatible with prolonged survival. However, a number of reports exist indicating a duration of from several months to several years. No documented cases were found to compare, either in length of life after the episode or in degree of pulmonary artery occlusion, with our patient who survived about 6 year...

Congenital pressure gradients between main pulmonary artery and its primary branches.

course of 594 diagnostic cardiac catheterizations. They occurred either alone: i6 cases (group I) or more often combined with congenital heart disease: IIO cases (group 2), about half of which were atrial septal defect. Angiographicfindings and pressure gradients were correlated in 33 cases. A minor gradient across thejunction of the main pulnonary artery with one of the branch pulmonary arteri...

Pulmonary changes and cor pulmonale in mucoviscidosis.

Chronic cor pulmonale in pulmonary sarcoidosis.

Right-heart overload happens relatively rarely in sarcoidosis, even with fibroemphysematous changes. Of 21 cases that we studied, six (28%) had clinical and/or electrocardiographic features of cor pulmonale. The cause of cor pulmonale often evoked is an invasion of the walls of pulmonary vessels by sarcoid granulomas or their compression by the fibrotic process. Pathological studies in one pati...
