Ultrasound manifestations of mitral valve prolapse

Mitral valve prolapse is a disease that we should pay attention to. This disease occurs in our ventricles. After it occurs, it will seriously affect our heart, so we should have regular physical examinations. Ultrasound examination is a relatively common examination. Mitral valve prolapse has certain ultrasound manifestations. So what are the ultrasound manifestations of mitral valve prolapse?

Mitral valve prolapse (MVP) is a

The mitral valve and/or subvalvular apparatus (including the valve ring, valve leaflets, chordae tendineae, papillary muscles and the ventricular wall at their attachments) are lesions, causing one or both leaflets of the mitral valve to bulge upward and backward excessively during systole and fall into the left atrium, with or without mitral valve closure failure.

A series of clinical syndromes caused by the whole disease [1].

Two-dimensional and M-mode echocardiography

Hemodynamic changes and cardiac function measurements: Simple MVP did not cause significant hemodynamic changes. In patients with MVP combined with moderate or above regurgitation, the hemodynamic changes are the same as those of "mitral regurgitation". Acute mitral regurgitation or insufficiency

In cases of sudden exacerbation, the load on the left atrium and left ventricle suddenly increases, which can cause acute left heart failure, but the left ventricular enlargement is disproportionate to the regurgitation volume. The left heart should be carefully measured

Cavity size.

The EF value may increase during the compensatory period. In the late stage, pulmonary artery pressure increases, right heart hypertrophy occurs, and left and right heart functions decrease.

The morphology of the valve and subvalvular structures and the echogenicity of the valve mucosa degeneration.

The valve leaflets become thicker and/or the chordae tendineae become loose and lengthy, with increased softness and mobility.

The valve leaflets and chordae tendineae may be enlarged and even drift with the blood flow. The echo reflexes of the valve leaflets and chordae tendineae may be loose and disordered, or the echo reflexes of the chordae tendineae may be loose, thin, elongated, or broken.

"SAM" phenomenon similar to hypertrophic cardiomyopathy. The mitral valve was found to be elongated and thickened

This suggests possible complications.

The long axis section of the left ventricle shows that the posterior leaflet of the mitral valve bulges toward the left atrium during systole.

The characteristic performance of valve leaflet movement is that the mitral valve leaflets move upward and

Moving backward, the valve body dislocates into the left atrium, exceeding the level of the valve ring line, and the leaflet coaptation point may be below or above the level of the valve ring. It can be normal alignment or abnormal alignment.

It can also be that both the alignment and the incarnation are abnormal, or the alignment is abnormal and the incarnation is normal.
