MITRAL VALVE REPLACEMENT

Disease

MITRAL VALVE REPLACEMENT is a cardiac surgery aimed at fixing a valve stenosis (closing or reducing valve orifice) or insufficiency (regurgitation flow). The mitral valve located between the left atrium and the left ventricle has the function of preventing the backflow of oxygenated blood coming from the lungs. Once the valve is open, blood flows from the atrium into the left ventricle. Its closure coincides with the contraction of the ventricle, thus directing the output of blood into the aorta and therefore throughout the body. The mitral valve comprises two leaflets Surgery is indicated when there is no effective opening or closing to maintain the blood flow. Mitral stenosis does not allow the left ventricle to get filled with enough blood causing an obstacle that generates increased pressure, which is transmitted to the lungs. This hinders an increase in the flow of blood to the body during physical activity causing fatigue and dizziness. In mitral regurgitation, one or both leaflets do not close properly for several reasons, leading to reflux and causing heart contractions to be more forceful in order to supply the same amount of blood. The heart can compensate for this overload for months or years, but it will show signs of damage and eventual failure. This translates into symptoms of progressive fatigue.

What causes mitral valve problems?

Mitral valve problems are rarely due to a genetic defect. Often there is a degenerative process caused by age or otherwise, causing changes in the mechanical function of the valve. Rheumatic fever can cause the most damage to the valve, leading to both stenosis and insufficiency. In this case, the damage is caused by the Infection of the Leaflets, which is called Bacterial Endocarditis. Myocardial Ischemia can also damage the opening and closing mechanisms of the valves.
