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 ...
A heart contains four valves (tricuspid, pulmonary, mitral and aortic valves) which open and close as blood passes through the heart. [3] Blood enters the heart in the right atrium and passes through the tricuspid valve to the right ventricle. From there, blood is pumped through the pulmonary valve to enter the lungs.

Mitral valve replacement is a procedure whereby the diseased mitral valve of a patient's heart is replaced by either a mechanical or tissue (bioprosthetic) valve. The mitral valve may need to be replaced because: [citation needed] The valve is leaky (mitral valve regurgitation) The valve is narrowed and doesn't open properly (mitral valve stenosis)
The mitral valve gets its name from the resemblance to a bishop's mitre (a type of hat). It is on the left side of the heart and allows the blood to flow from the left atrium into the left ventricle. During diastole, a normally-functioning mitral valve opens as a result of increased pressure from the left atrium as it fills with blood ...
Compared to patients who need open heart surgery, patients who received mitral clip have less need for a blood transfusion and have fewer ventilation days. [4] When compared to the patient who has had open heart surgery, MitraClip was cheaper - approximately $2200 less per person - and the median stay in the hospital post mitral clip is 2.4 days.
Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. [1] It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm 2 during diastole. Any decrease in area below 2 cm 2 causes mitral stenosis. Early diagnosis of mitral stenosis ...
