What is mitral valve regurgitation?

Many people may not have heard of what mitral valve regurgitation is specifically. In fact, the valve generally refers to the atrium position of the heart, and the mitral valve refers to a position in the heart. Mitral valve regurgitation has a significant impact on the function of the heart.

Basic Introduction

Classification:

1. Atrioventricular valves: including the mitral valve (located between the left ventricle and the left atrium) and the tricuspid valve (located between the right ventricle and the 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.
