2022年12月20日 · Pulmonary valve stenosis is a narrowing of the valve between the lower right heart chamber and the lung arteries. In a narrowed heart valve, the valve flaps may become thick or stiff. This reduces blood flow through the valve.

Approximately 10–20% of cases involve pulmonic valve dysplasia. Dysplastic valves are trileaflet with thickened cusps composed of myxomatous tissue and little or no fusions, with relative valve immobility.

2023年2月23日 · Types of pulmonary valve disease include: Pulmonary valve stenosis. Narrowing of the pulmonary valve reduces the blood flow from the heart to the pulmonary artery and lungs. Pulmonary valve regurgitation. The flaps of the pulmonary valve don't close tightly. Blood moves backward into the right lower heart chamber, called the right ventricle ...

When dysplasia of the pulmonary valve is identified clinically and echocardiographically, balloon dilatation is unlikely to improve haemodynamic function; it should be attempted if commissural fusion is present.

When dysplasia of the pulmonary valve is identified clinically and echocardiographically, balloon dilatation is unlikely to improve haemodynamic function; it should be attempted if commissural fusion is present.

In some cases, the pulmonary valve may be dysplastic, thickened, and without fusion. Patients with Noonan syndrome often have a hypoplastic pulmonary annulus and hypoplastic proximal pulmonary arteries.

A dysplastic pulmonary valve usually requires surgical treatment, while a domed pulmonary valve stenosis usually can be treated with balloon valvuloplasty. RV outflow tract obstruction due to conduit stenosis, homograft stenosis and some prior bioprosthetic valve dysfunction may be treated with a percutaneous pulmonary valve replacement.

In this dysplasia there are characteristic clinical and angiographic findings which allow differentiation from typical pulmonic stenosis. Pathologically the dysplastic valve is tricuspid, unfused, markedly thickened and inflexible, and literally stuffs up a …

2017年8月31日 · Dysplastic pulmonary valve stenosis is a less common variety of valvular pulmonary stenosis. It is known to be part of Noonan syndrome. Bony hand anomalies in patients of pulmonary stenosis are very rare.
