11 Surprising Symptoms Associated With Noonan Syndrome

2. Pulmonary Valve Stenosis

Pulmonary valve stenosis happens when a deformity of the pulmonary valve causes it to narrow, restricting blood flow. This condition is a common congenital heart defect in Noonan syndrome patients. Symptoms range in severity, and they generally include shortness of breath, chest pain, fainting, heart murmurs, and fatigue. Patients with pulmonary valve stenosis are at an increased risk of endocarditis, arrhythmias, and heart failure. To diagnose this form of stenosis, doctors do a physical exam, and echocardiograms, electrocardiograms, and MRI or CT scans may be needed. Some patients might also need to undergo a cardiac catheterization procedure. If the patient's symptoms are mild, treatment for this ailment may consist solely of regular checkups. For patients with more severe symptoms, balloon valvuloplasty, valve repair, or valve replacement surgeries may be recommended.
