Pulmonary Valve Stenosis
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
Pulmonary stenosis: Treatment for pulmonary valve stenosis varies depending upon the severity of stenosis and symptoms, and whether this is an isolated finding or there are other comorbid issues. Generally patients with mild to moderate stenosis may not require intervention, whereas patients with moderate to severe stenosis might require a catheter -or surgical-based approach to open up the narrowing. ...Read more
Depends: Depends on age, size of infundibulum, pulmonary annulus, tricuspid or bicuspid valve or degree of pulmonary atresia, primary or redo after previous congenital cardiac surgical repair. If it is a newborn and the annulus size is good and magoon ratio good, simple balloon angioplasty can be considered. Later on stented bioprosthesis can be considered. Otherwise pulmonary homograft at birth may be need. ...Read more
Pulmonary stenosis: Mild to moderate pulmonary valve stenosis generally has a good prognosis. Mild pulmonary valve stenosis usually does not progress, but moderate pulmonary valve stenosis may worsen over time and require surgery. Treatment is generally highly successful allowing people to live high quality lives provided that they do not have other comorbid problems. ...Read more
Pulmonary stenosis: There are a number of variables that pediatric cardiologists and heart surgeons take into consideration when determining how to approach pulmonary valve stenosis in a neonate. Generally speaking, a catheter-based approach is desirable to avoid surgery, and may be attempted first provided that the anatomy and other patient factors are amenable to that. ...Read more
My eight month old daughter was just diagnosed with pulmonary valve stenosis. Can you tell me more about this?
Severity?: It is a congenital defect in which the valve that allows blood to pass out of the right ventricle into the pulmonary artery and lungs doesn't open properly. If mild, it causes no symptoms. If severe, it can strain the right ventricle which eventually will fail. The valve can be stretched open with a catheter (valvuloplasty) or replaced with surgery. ...Read more
What do you suggest if my eight month old daughter was just diagnosed with pulmonary valve stenosis. anyone have an experience with this?
Pulmonary stenosis: She needs to be evaluated by a Pediatric Cardiologist. Then you need to get a discussion from that Doc. ...Read more
Excellent: Isolated pulmonary valve stenosis, even if severe, has an excellent long-term outcome. Mild pulmonary valve stenosis is typically asymptomatic with normal exercise tolerance and normal lifespan. Significant pulmonary valve stenosis typically can be successfully treated with balloon valvuloplasty (a safe procedure) and after treatment, patients have an excellent long-term outcome. ...Read moreSee 2 more doctor answers
The heart has 4 chambers. The right ventricle is the pumping chamber whic h pushes blood into the lungs so oxygen can be put into the blood. When the right ventricle squeezes, the pulmonary valve opens and blood flows into the lungs. When the right ventricle relaxes to fill, the pulmonary valve closes so blood can't flow backwards ...Read more
