PATHOLOGY

Detailed explanation-1: -Mitral valve regurgitation is a type of heart valve disease in which the valve between the left heart chambers doesn’t close completely, allowing blood to leak backward across the valve.

Detailed explanation-2: -Heart attack or coronary artery disease, both of which can damage the heart muscles surrounding the mitral valve. Cardiomyopathy, a weakened heart muscle resulting from hypertension, heart attack, viruses or inherited disease. Congenital heart defects, or structural heart issues present at birth.

Detailed explanation-3: -The mitral valve controls the flow of blood from the heart’s left atrium to the left ventricle. A prolapsed mitral valve means that the valve’s flaps do not always fit and close properly between each beat of the heart, which may cause the valve to leak blood backward through the valve back to the left atrium.

Detailed explanation-4: -Causes. Mitral valve prolapse is usually caused by problems with the tissues that join the mitral valve to the heart muscles. Some people with the condition are born with it, and it’s more common in people with connective tissue disorders, such as Marfan syndrome.
