Exactly what is mitral valve prolapse?
Mitral valve prolapse (MVP) is still amongst the extra widespread heart illnesses; despite the fact that it remains some thing of a puzzle. Now while MVP affects around two percent of the population, the cause is still unknown and has scientist wanting to know what does cause it. MVP normally occurs in men and women who’ve no other heart issues, and the condition may well be inherited.
The mitral valve is situated within the heart between the upper-left chamber (the left atrium) along with the lower-left chamber (the left ventricle). The mitral valve consists of two flaps referred to as leaflets.
In normal operation the leaflets open and close in a distinct sequence. This permits the blood to flow in 1 direction, from the atrium to the ventricle. The left ventricle will be the heart’s major pumping chamber and pushes oxygen-rich blood into the arteries, which carry the blood all through the body.
In patients with MVP, one or both of the leaflets are enlarged, and also the leaflets’ supporting muscles are too long. Instead of closing evenly, one or both of the leaflets collapse or bulge into the atrium occasionally permitting modest amounts of blood to flow back into the atrium. By listening to the heart having a stethoscope, the physician may perhaps hear a “clicking” sound caused by the flapping of the leaflets.
Occasionally, MVP leads to a condition known as mitral regurgitation or mitral insufficiency. This indicates a substantial amount of blood is leaking backward via the defective valve. Mitral regurgitation can result in the thickening or enlargement of the heart wall. This is caused by the extra pumping the heart should do to make up for the backflow of blood. It in some cases causes individuals to really feel tired or short of breath. Mitral regurgitation can normally be treated with medicines, and some individuals want surgery to repair or replace the defective valve.
