   [3] [4] [5] It is the abnormal leaking of blood backwards – regurgitation from the left ventricle, through the mitral valve, into the left atrium, when the left ventricle contracts. [4] Mitral regurgitation is the most common form of valvular heart disease. [3]

   This causes a leaking of blood from the aorta into the left ventricle. This means that some of the blood that was already ejected from the heart is regurgitating back into the heart. The percentage of blood that regurgitates back through the aortic valve due to AR is known as the regurgitant fraction.

   The mitral valve, so named because of its resemblance to a bishop's mitre, is the heart valve that prevents the backflow of blood from the left ventricle into the left atrium of the heart. It is composed of two leaflets, one anterior and one posterior, that close when the left ventricle contracts. [35]

6. Mitral valve repair - Wikipedia

   en.wikipedia.org/wiki/Mitral_valve_repair

   Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart.

   The mitral valve is typically 4 to 6 square centimetres (0.62 to 0.93 sq in) in area and sits in the left heart between the left atrium and the left ventricle. [5] It has two cusps: an anterior one, and a posterior one. [6] The opening of the mitral valve is surrounded by a fibrous ring known as the mitral annulus. The anterior cusp attaches to ...
