Function of heart valves

In fact, the functionality of the heart valve is quite powerful. If there is a problem in this part of your heart, it will affect your entire physical condition and cause very serious damage to your health. If necessary, you must do an X-ray examination. Only in this way can you know very clearly which part of your heart has a problem and find the best treatment method.

Classification: 1. Atrioventricular valve: including mitral valve (located between the left ventricle and left atrium) and tricuspid valve (located between the right ventricle and right atrium). 2. Semilunar valves: including the pulmonary valve (located at the outlet of the right ventricle) and the aortic valve (located at the outlet of the left ventricle).

Think of the valve as a sail: Under normal circumstances, the sail is filled with wind and inflated to the perfect size; but in mitral valve prolapse, the sail is too big, or the rigging is too long, so the sail flaps in the wind, becomes slack, and some of the wind (i.e., blood) passes through the sail. This abnormal phenomenon can disturb the nerves in the atria, causing palpitations and sweating.

Fifteen percent of women are diagnosed with mitral valve prolapse. Although men can also experience valvular abnormalities, the syndrome of palpitations, sweating, and panic attacks associated with floppy valves usually occurs in young women. This valve problem should be treated with beta-blockers, but most people just let it go.

The most commonly affected valve is the mitral valve, followed by the aortic valve. Heart valvular disease is caused by structural damage, fibrosis, adhesion, shortening, myxomatous degeneration, ischemic necrosis, calcification or congenital malformations caused by inflammation of the heart valves (including leaflets, chordae tendineae and papillary muscles). The disease mostly occurs in young and middle-aged people aged 20 to 40, 2/3 of whom are women, and most have a history of rheumatic fever. Only mitral valve and aortic valve diseases are discussed here.

1. There may be no symptoms during the compensatory stage, but when left heart failure occurs, there may be palpitations, shortness of breath, fatigue, etc.

2. The cardiac border expands to the left; a loud, rough systolic blowing murmur can be heard in the apex area, often transmitted to the armpit or back; the third heart sound can be heard; the second heart sound in the pulmonary valve area is hyperactive.

3. Auxiliary examination:

⑴ X-ray examination: enlarged left atrium and left ventricle, prominent pulmonary artery segment.

⑵ Electrocardiogram examination: left atrial enlargement, left ventricular hypertrophy and strain.

⑶ Echocardiography examination: When the left atrium and left ventricle are enlarged, the M-type diagram can be detected.
