心脏瓣膜病的危害机制二尖瓣狭窄心脏舒张期从左心房流向左心室的血流受阻,引起左心室充盈不足的同时,左心房内随着压力的增加而内径逐渐呈被动性扩大,因回到左心房的血流受阻而造成肺静脉淤血,由此可以诱发肺水肿和咯 Heart valve disease hazards mitral stenosis diastolic flow from the left atrium to the left ventricular blood flow blocked, causing insufficient left ventricular filling at the same time, with a pressure increase in the left atrium and gradually increased the passive diameter, due to the back Pulmonary venous congestion is blocked by the blocked blood flow to the left atrium, and pulmonary edema and cough can be induced
