What is valvular heart disease?

Valvular heart disease refers to damage to one or more of the four heart valves (aortic, pulmonary, mitral and tricuspid). Among them, aortic stenosis and aortic regurgitation occur in the aorta.

A mild stenosis lesion of the heart valves that causes no obvious symptoms. Moderate or severe stenosis can cause fatigue or atrial fibrillation. Combined, the risk of stroke is 20 times higher than in healthy people.

Common mitral valve diseases can be divided into: mitral regurgitation (MR) and mitral stenosis (MS).

Mitral regurgitation is the most common valvular disease. The symptom of MR Is systolic flow back from the left ventricle to the atrium, which is caused by a variety of causes. MR Patients account for 65% of all mitral regurgitation patients and approximately 50% of all heart valve disease.

Mitral stenosis is the most common, rheumatic heart disease is the main cause, mild or moderate stenosis, can be repaired with surgery.

Stenosis of the tricuspid and pulmonary valves is relatively rare, and pulmonary stenosis is common in patients with congenital heart disease.

Leading cause of valvular heart disease

Some are congenital. Others are born with normal valves but later develop abnormalities for some reason, such as infection or systemic disease.

1. Inflammation

Rheumatic fever is a major cause of valvular heart disease. A common lesion is the mitral valve, and endocarditis can cause the heart valves to regurgitate.

One of the long-lasting effects of the infection is damage to a valve in the heart.

2. Degenerative valve disease

As people age, degenerative changes can occur in heart valves, with most common lesions occurring in the main artery valve, followed by the mitral valve.

3. Other diseases

Congenital malformations, mucoid degeneration, ischemic necrosis, heart disease, and high blood pressure, high cholesterol, and diabetes can also cause disease.

TAVR is very popular in this industry.
