What problems can result from untreated or advanced tricuspid valve stenosis?
随着线上电子游戏飞禽走兽的推移, the right atrium can become enlarged because blood flow through the narrow tricuspid valve opening is restricted. An enlarged atrium can affect the pressure and blood flow in the nearby chambers and veins.
The pressure in the right ventricle could be lower because the amount of blood entering from the right atrium is reduced. This could result in less blood circulating through the lungs to get oxygen.
