What is mitral klaffs vikt (mitral regurgitation)?
Mitral regurgitation
Mitral valve is the name of the heart valve between the left ventricle, and the flap should normally prevent blood from flowing back into the left atrium when the heart chamber contracts. When blood flows in the wrong direction through the flap, there mitralklaffsvikt.
This is the second most common valve defect, by narrowing of the aortic valve (the valve to the aorta). Mitral klaffs vikt often seen as an additional phenomenon to enlargement of the left ventricle in heart failure (valve apparatus is put on stretch).
What causes mitral klaffs vikt?
Mitral klaffs vikt can have many causes. However, often it is associated with injury due to hypoxia, such as in myocardial infarction. An infarction can cause the threads to hold the flaps in position is too slow or described above. The muscles that tighten and control wires to the valves can also be damaged. Disorders of the connective tissue in the heart can as well cause failure flap function. Previously, rheumatic fever, a common cause, but this is now very rare.
Mitral klaffs vikt can also be congenital.

How is a long-term outlook at mitralklaffsvikt?
If cardiac function is not damaged before surgery, life outlook is good after surgical treatment. All patients suspected of this disease will be referred to a cardiologist, to set definite diagnosis and assessment of timing of surgery.
The increased load on the heart because of the leak can be in the longer term provide enlargement of the left ventricle and atrium. The increased pressure is obtained in the antechamber may propagate into the pulmonary circulation and provide an elevated pressure here, which in turn can lead to failure also in the right half. Long-term outlook depends on the severity and cause. Acute rupture of wires or muscle flap in the appliance, or inflammation of the heart valves, have poorer prognosis.
In acute mitral klaffs vikt may cause serious respiratory problems because of the severe buildup of water from the lungs and development of shock.
