Is severe mitral stenosis of the heart serious?

Severe mitral stenosis can usually lead to complications such as atrial fibrillation, pulmonary edema, and heart failure, which are generally serious.
The mitral valve is usually composed of two leaflets located between the left atrium and the left ventricle. When the mitral valve is severely narrowed by a lesion, blood cannot normally enter the left ventricle from the left atrium, resulting in enlargement of the left atrium, exertional dyspnea, pulmonary hypertension, and atrial fibrillation, which ultimately can lead to heart failure, which is usually more serious.
The causes of mitral stenosis usually include rheumatic fever, congenital developmental abnormalities, degenerative changes in old age, etc. Therefore, if the patient has severe mitral stenosis, it is recommended to go to the cardiology department of the hospital in a timely manner for examination, to clarify the causes, and follow the doctor’s instructions for active treatment.
