Question 1

what are the tests for absent pulmonary valve?

Accepted Answer

Obvious at birth: Pulmonary valve atresia will render the child blue at birth and the pediatric cardiology team will probably be able to make the call in a very short time.  If this has happened to you, i wish you and your child the best of luck; today's surgery helps many of these babies.

Question 3

what sort of problem is an absent pulmonary valve?

Accepted Answer

Absent/ never formed: The defect occurs when an unopen artery without a valve cannot carry blood to the lungs. This is ok during pregnancy since fetal lungs don't need to receive blood & add o2.Blood is pumped thru bypass circuits to the body.After birth, when lungs must supply o2,  this can be a fatal defect.If recognized early, drs can keep the bypass open & heart surgeons can reroute the flow with open heart surgery.

Question 4

what happens if you are ?born?with a v.s.d with absent pulmonary valve?

Accepted Answer

Serious: This is a serious problem, but generally is correctable with the proper surgery.What happens is that the heart does not handle your blood properly leading to potential heart and tissue damage from overwork and lack of oxygen.

Question 5

what are the advantages and disadvantages of different treatments for absent pulmonary valve?

Accepted Answer

Probably none needed: If born this way, there probably is nothing that absolutely needs to be done because of an absent pulmonic valve per se.  The valve adds to efficient function of the "right" (vs. Left) sided heart chambers, but the heart may compensate by itself.  Any active intervention may be fraught with more risk than benefit, but consulting a pediatric cardiologist is prudent to confirm this & get best advice.

Question 6

how is a pulmonary valve stenosis treated?

Accepted Answer

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.

Question 7

what are recommendations for pulmonary valve stenosis repair in infants?

Accepted Answer

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.

Question 8

what is the function of the pulmonary valve?

Accepted Answer

Flow direction: Pulmonic valve like all other heart valves, directs the flow from one chamber to another, in this case from the right ventricle to the lungs.  It allows the flow to be organized and the timing of flow to be proper.

Question 9

what is the definition or description of: pulmonary valve?

Accepted Answer

Valve in the heart: 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 back into the heart.

Question 10

how do you get treated if you have pulmonary valve stenosis?

Accepted Answer

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.
