echocardiography ใช้ประเมิณอะไรบ้าง

 

echocardiography finding of MR

- mild regurgitation : no flow convergence and a small regurgitant jet area

- severe central MR: a prominent flow convergence and large regurgitant jet area

- severe eccentric MR: small jet area impinging on the wall of the left atrium but a large flow convergence and a wide vena contracta.
