What is tricuspid insufficiency?

Tricuspid valve insufficiency may be caused by congenital malformations, rheumatic heart disease, coronary atherosclerotic heart disease, etc.

1. Congenital abnormalities of

tricuspid valve in patients with congenital malformations may cause tricuspid valve insufficiency when they cause structural and functional abnormalities of tricuspid valve.

2. Streptococcal infection of rheumatic heart disease

may cause rheumatic heart disease, resulting in damage to tricuspid valve, resulting in increased systolic pressure of right ventricle, causing tricuspid valve annulus dilatation, resulting in tricuspid valve insufficiency.

3. Coronary

atherosclerotic heart disease in patients with coronary atherosclerotic heart disease may cause myocardial ischemia, hypoxia, necrosis, resulting in abnormal cardiac function, resulting in tricuspid valve insufficiency.
