Syndrome Noonan Quebec Valve Stenosis -

About 80 per cent of children with Noonan syndrome have heart abnormalities. The most common include: pulmonary valve stenosis 50-80%: the pulmonary valve allows blood with reduced oxygen content deoxygenated to leave the heart and go to the lungs. Ultrasound abnormalities associated with Noonan syndrome consist of polyhydramnios, cystic hygroma, anatomical cardiac abnormalities, and fetal musculoskeletal anomalies. Most people with Noonan syndrome have congenital heart disease [7]. The most common cardiac conditions are pulmonary valve stenosis and hypertrophic cardiomyopathy. It is estimated that 50-80 percent of individuals with Noonan syndrome have a congenital heart defect. The most common heart defect seen is pulmonary valve stenosis, which is a narrowing in the valve attached to the blood vessel that carries blood out of the heart to the lungs.

Noonan syndrome NS is an autosomal dominant disorder with prevalence of 1:1000 to 1:2500. Cardiac defects are present in up to 70%–80% of patients, pulmonary valve stenosis PS being the most common in about 50% followed by atrial septal defect ASD in ~ 20% and then hypertrophic cardiomyopathy HCM in ~ 15%. The most frequent cardiac abnormality in Noonan’s. syndrome is pulmonary valve stenosis, present in approxima tely 50% of the patients 3, followed by hypertrophic myocar diopathy occurring in 25% 4. Pulmonary valve stenosis is one of the common issues linked to the syndrome. The condition causes the narrowing of the pulmonary valve. The pulmonary valve is the tissue flap separating the ventricle lower right chamber of the heart from the pulmonary artery the artery supplying blood to the lungs. Noonan syndrome is a disorder of development. Patients with this syndrome are considered failure to thrive—meaning they struggle to gain adequate weight due to eating difficulties. Despite normal birth weight, insufficient levels of growth hormones delay bone growth.

Because Noonan syndrome may be difficult to confirm in such cases particularly if there is no family history of the disorder, Noonan syndrome should be strongly considered as a possible diagnosis in any individuals with pulmonary valve stenosis and certain eye abnormalities typically found even in the more mild cases e.g., ptosis, epicanthal. Noonan syndrome NS is a genetic disorder that may present with mildly unusual facial features, short height, congenital heart disease, bleeding problems, and skeletal malformations. Facial features include widely spaced eyes, light-colored eyes, low-set ears, a short neck, and a small lower jaw. Heart problems may include pulmonary valve stenosis. Jan 15, 2014 · Noonan syndrome NS is a genetic disorder caused by mutations altering proteins relevant to RAS/mitogen-activated protein kinase MAPK signal transduction. Cardiac involvement is common, most prevalently pulmonary valve stenosis and hypertrophic cardiomyopathy. “Degenerative” or calcific aortic stenosis is a complex, multifaceted, systemic disease that is not solely limited to the aortic valve but also includes reduced arterial compliance as well as alterations of left ventricular geometry and function. This particular nature of the disease underscores the need for a more comprehensive evaluation of disease severity going beyond the standard.
