  1. Pulmonary Valve Stenosis Bria Peacock

  2. What is the Pulmonary Valve? • It is a valve that separates the right ventricle from the pulmonary artery. • Through it, deoxygenated blood flows to the lungs by way the pulmonary artery to receive oxygen. • The now oxygenated blood then flows back to the heart and then to the rest of the body.

  3. Pulmonary valve stenosis • The valve is narrowed in this disorder. • Because it does open wide enough, less blood gets to the lungs.

  4. Symptoms • Abdominal swelling • Bluish color to the skin • Chest pain • Fainting • Fatigue • Poor weight gain • Shortness of breath • Sudden death

  5. Causes • Birth defect • Cause unknown

  6. Frequency • Rare • May run in families—genetic

  7. Risk Factors • Family history of heart defect • Chromosomal disorders • Heart defects • History of pregnancy with fetal heart abnormalities or miscarriage • Viral infection during pregnancy

  8. How is the disease identified • Heart murmur when listening to heart • Chest x ray • ECG—electrocardiogram which records the electrical activity of the heart • Echocardiogram creates a picture of the heart with sound waves • MRI or the heart creates a picture of the heart with magnets and radio waves • Cardiac catheterization is when a catheter is guided into either side of the heart from the groin or arm

  9. Treatment • If mild, treatment is probably not needed • Medications could be used to treat the defects caused such as preventing clots with blood thinners and treating abnormal rhythms • Percutaneous balloon pulmonary dilation is done to widen the valve • Heart surgery
