Congenital supraglottic laryngeal obstruction still is being described as subglottic stenosis. There are three clearly defined types of congenital laryngeal atresia, which result from arrest at consecutive developmental stages. Type 1 consists of a supraglottic obstruction, absent vestibule, and stenotic infraglottis, and type 2 is a supraglottic obstruction that separates ...
Cooley D A - - 1988
Recently, there has been an increasing emphasis on definitive correction of congenital heart defects at an early age. Nevertheless, in the presence of severe cyanotic congenital heart disease, survival may depend on palliative techniques designed either (1) to promote increased pulmonary blood flow by means of a systemic-pulmonary artery shunt ...

Interventional radiologic techniques have been applied to the management of congenital cardiovascular abnormalities. Transcatheter embolization is now the procedure of choice in the treatment of pulmonary arteriovenous malformations. Transluminal angioplasty has been successfully employed in the management of patients with congenital pulmonary and aortic valvular stenosis and may also be ...
Huhta J C - - 1987
Fetal echocardiography has yet to have an impact on the treatment of congenital heart disease. Critical aortic valve stenosis was diagnosed by echocardiography before birth in a 35 week gestation fetus. The risks to the fetus and mother associated with prolonged rupture of membranes prompted their transport to a hospital ...
Rothschild P A - - 1987
The diagnosis of herniation of the left ventricle through a pericardial window was made using MRI. This is a rare type of herniation because it presented 6 years after a pericardial window was made for pericarditis. Herniation of the heart through congenital, traumatic and post surgical pericardial defects are discussed.

Post-mortem arteriography, properly carried out, visualizes the whole extent of the arterial vascular system. The intimate relationship of parenchymatous organs to their arterial supply makes it possible to identify and localize the individual structure, even where there are abnormalities. Arteriography has never been methodically applied to post-mortem examinations of fetuses ...
Belcourt C L - - 1986
Congenital stenosis of individual pulmonary veins is uncommon. Of the 49 cases reported, four were seen at the IWK Hospital for Children and are reported here. Plain radiographs show a shift of the heart toward the side of major involvement, Kerley B lines, fluid in the fissures, and interstitial edema ...
Fingland R B - - 1986
In a retrospective study of 29 dogs with congenital pulmonic stenosis, we evaluated the clinical, radiographic, angiocardiographic, and cardiac catheterization data.
