	MITRAL VALVE REPAIR (text)
		Mitral valve repair is an open heart procedure performed by cardiothoracic surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve.
		Congenital mitral regurgitation may be due to a cleft mitral valve (a valve with a separation or cleft down the middle) associated with an atrial septal defect, a type of hole in the heart between the low pressure chambers or atria.
		Degenerative mitral valve disease may be due to an elongation or rupture of the chordal apparatus, the "heart-strings" that support the valve normally, or due to a more generalized weakness of the valve itself such as the "floppy valve" syndrome in which all of the components of the valve are enlarged and elongated.

	Heart valve repair or replacement for mitral valve regurgitation or prolapse
		For instance, repair is more successful if there is limited damage to certain areas of the mitral valve flaps (leaflets) or to the tough fibers that control movement of the mitral valve leaflets (chordae tendineae).
		Repair of the heart valve usually is the preferred and more common type of surgery for MVP because it is a simpler surgical procedure and has a lower risk of infection.
		The decision regarding whether to repair or to replace a valve is based on many factors, including the person's general health, the condition of the damaged valve, the presence of other health conditions, and the expected benefits of surgery.

	Mitral valve prolapse&repair "heart matters
		Mitral valve prolapse is a condition in which the valve (called the mitral valve) between the upper chamber (the atrium) and lower chamber (the ventricle) on the left side of the heart bulges into the upper chamber when the heart contracts.
		The function of the mitral valve is to allow blood flow to occur between these two chambers during contraction of the heart, and to close off blood flow during the relaxation phase of the heart.
		The best result of repair is achieved in myxomatous degeneration (noncalcific,nonrheumatic) group of patients.Mitral valve repair does not require anticoagulation per se if patient remains in normal sinus rhythem.Therefore the risk of thromboembolism (migratinig blood clot),endocarditis (valve infection), bleeding due to anticoagulation and prosthetic valve are eleminated.

		The mitral valve, shaped like a liturgical headdress worn by bishops and abbots called a miter, is the “inflow valve” for the left ventricle, the heart’s main pumping chamber.
		Mitral valve surgery was first performed in 1960, when surgeons replaced the diseased, native valve with an artificial valve.
		For the next 20 years, valve replacement was the gold standard, using either a metal, mechanical valve or a valve made from cow tissue.

		The most common heart valve abnormality is called Mitral Valve Prolapse (MVP), which affects between 5 percent and 20 percent of the population.
		MVP is a condition of the mitral valve, a two-flapped heart valve between the left atrium and left ventricle.
		Because of this imperfect closing, the valve itself slightly balloons back into the left atrium, sometimes causing what is known as a "click." With the flap there may sometimes be a slight backward leaking of blood (regurgitation) as well, resulting in a heart murmur.

	This Week's Remarkable Minute: Mitral Valve Repair Takes A Step Forward - Evanston Northwestern Healthcare (Site not responding. Last check: 2007-11-04)
		5/14/2005 - After the leaky mitral valves in their hearts were repaired non-surgically with a tiny, catheter-fed clip, nearly all – over 90 percent – of the patients whose mitral regurgitation (MR) was significantly reduced one month after receiving the clip maintained the reduction at six months.
		Mitral regurgitation is a debilitating condition that occurs when the mitral valve, which allows blood to move through the heart, fails to close properly.
		With this device, we can provide a minimally invasive option for decreasing valve leakage without taking away the patient’s ability to have surgical valve repair in the future, if it’s needed,” says Principal Investigator Ted Feldman, MD, Director of the Cardiac Catheterization Lab at Evanston Hospital.

		If you decide on surgery to repair your mitral valve stenosis, you and your doctor will need to select either a balloon valvotomy or a mitral commissurotomy.
		In spite of similar success rates, a balloon valvotomy is generally preferred to either an open or closed mitral commissurotomy as long as the doctor is experienced with the procedure.
		Most commonly, "cracking open" valve leaflets will cause the valve to begin to leak, causing mitral regurgitation.
