Incision, Cardiology, Next Steps

We had an eventful last two weeks. Since learning about the pulmonary stenosis that threatens the free blood flow to the lungs from Ry' heart and her decreased right ventricle function, her incision site got a localized infection. We checked into the hospital on Sunday 9/09 and were released after monitoring and IV antibiotics Monday afternoon. She’s such a trooper. Her site looks much better now and her zipper is looking beautiful!

We saw her cardiologist on Wednesday 9/12, and she said we can come back in one month and they will see if there has been any changes in her heart (Echo and EKG). They want her to get to a couple of month from birth and surgery to do the next procedure as they want the area nicely healed. We don’t want to see her heart condition declining so the next procedure will be done as proactively as possible.

So what is ventricle stenosis and what can be done? For Ry she will have a balloon procedure at some point in the next month or two.

Pulmonary valve stenosis

Pulmonary valve stenosis is a heart valve disorder that involves the pulmonary valve.

This valve separates the right ventricle (one of the chambers in the heart) and the pulmonary artery. The pulmonary artery carries oxygen-poor blood to the lungs.
Stenosis, or narrowing, occurs when the valve cannot open wide enough. As a result, less blood flows to the lungs.

Causes, incidence, and risk factors
Narrowing of the pulmonary valve is usually present at birth (congenital). It is caused by a problem that occurs when the unborn baby (fetus) is developing. The cause is unknown, but genetics may play a role.

Narrowing that occurs in the valve itself is called pulmonary valve stenosis. There may also be narrowing just before or just after the valve.
The defect may occur alone or with other heart defects that are present at birth (congenital). The condition can be mild or severe.

Pulmonary valve stenosis is a rare disorder.
In some cases, pulmonary valve stenosis runs in families.

Many cases of pulmonary valve stenosis are mild and do not cause symptoms. These infants are usually found to have a murmur on a routine heart examination.

When the valve narrowing (stenosis) is moderate to severe, the symptoms include:

Symptoms may get worse with exercise or activity.

Signs and tests
The health care provider may hear a heart murmur when listening to your heart using a stethoscope. Murmurs are blowing, whooshing, or rasping sounds heard during a heartbeat.

Tests used to diagnose pulmonary stenosis may include:

The health care provider will grade the severity of the valve stenosis to plan treatment.

Sometimes, treatment may not be needed if the disorder is mild.
When there are also other heart defects, medications may be used to:

  • Help blood flow through the heart (prostaglandins)
  • Help the heart beat stronger
  • Prevent clots (blood thinners)
  • Remove excess fluid (water pills)
  • Treat abnormal heartbeats and rhythms

Percutaneous balloon pulmonary dilation (valvuloplasty) may be performed when no other heart defects are present.

  • This procedure is done through an artery in the groin.
  • The doctor sends a flexible tube (catheter) with a balloon attached to the end up to the heart. Special x-rays are used to help guide the catheter.
  • The balloon stretches the opening of the valve.
Some patients may need heart surgery to repair or replace the pulmonary valve. The new valve can be made from different materials. If the valve cannot be repaired or replaced, other procedures may be needed.

Expectations (prognosis)
Patients with mild disease rarely get worse. However, those with moderate to severe disease will get worse. The outcome is good with successful surgery or balloon dilation. Other congenital heart defects may be a factor in the outlook.

Most often, the new valves can last for decades. Others wear out and will need to be replaced.

  • Abnormal heartbeats (arrhythmias)
  • Death
  • Heart failure and enlargement of the right side of the heart
  • Leaking of blood back into the right ventricle (pulmonary regurgitation) after repair
