What's wrong with a small amount of tricuspid regurgitation in cardiac color Doppler ultrasound

Cardiac color Doppler ultrasound is a small amount of tricuspid regurgitation may be caused by congenital tricuspid valve malformation, rheumatic heart disease, pulmonary artery stenosis and other reasons.

1. Congenital tricuspid valve

malformation in patients with congenital tricuspid valve malformation, may cause the ventricular septum and posterior leaflet annular tissue inserted into the top displacement, ventricular myocardium appears atrial situation, causing this symptom.

2.

Rheumatic heart disease in patients with rheumatic heart disease, the lesion may involve tricuspid valve, resulting in diffuse thickening of the valve, leaflet tissue deformation, at this time will also occur a small amount of tricuspid regurgitation.

3.

Pulmonary artery stenosis in patients with pulmonary artery stenosis, may cause abnormal right ventricular dilatation, pulmonary artery pressure increased, resulting in a small amount of tricuspid regurgitation performance.
