What is Mitral Regurgitation?

Mitral regurgitation is a heart valve condition where the mitral valve does not close properly, causing blood to leak backward into the left atrium. This can lead to symptoms like fatigue, shortness of breath, and heart enlargement if untreated. It is one of the most common valvular heart diseases, affecting millions worldwide, and can be caused by age-related degeneration, rheumatic heart disease, or structural abnormalities.
