The clinical significance of the increased pulmonary arterial stiffness in the absence of stenosis remains to be clarified.
In most children, stenosis of the pulmonary valve is mild and non-progressive; ventricular function is normal and exercise capacity is not impaired.
The process may be progressive and lead to pulmonary venous stenosis.
In conclusion, long-term survival is related to age and severity of aortic stenosis at presentation.
Placement of balloon-expandable stents in surgically created pulmonary artery stenosis: gross and histologic observations.
There is posterior deviation of the outlet septum giving rise to muscular subpulmonary stenosis.
The second apical diastolic murmur he described was the murmur of mitral stenosis that changed when "total arrhythmia" or "auricular" fibrillation appeared.
Injections into each of the pulmonary veins revealed tight stenoses of all veins at the veno-atrial junction, especially the right upper and middle pulmonary veins.
