Why does diastolic murmur increase in mitral stenosis

Mitral

stenosis is a heart disease in which the mitral valve cannot be opened normally due to various reasons. For patients with mitral stenosis, because the opening of the mitral valve narrows, the blood is blocked from passing through the valve tissue during diastole, resulting in the inability of the blood to pass smoothly. The heart will form greater pressure to urge the blood to pass through the stenosis site, resulting in increased murmurs when the blood passes through the valve tissue. It is suggested that patients with abnormalities should seek medical treatment in time for corresponding treatment.
