	Lifespan's A - Z Health Information Library - Mitral stenosis (Site not responding. Last check: 2007-10-23)
		Mitral stenosis is a narrowing or obstruction of the opening of the mitral valve, which separates the upper and lower chambers on the left side of the heart.
		Mitral stenosis prevents the valve from opening properly and obstructs the blood flow from the left atrium to the left ventricle.
		Mitral stenosis may be difficult to distinguish from left atrial myxoma (a tumor of the heart).

		The typical adult patient is a woman whose mitral valve was damaged by rheumatic fever.
		Mitral regurgitation — As in mitral stenosis, the cause is usually rheumatic fever, but the patient is usually an adult male.
		Mitral valve prolapse — In this condition, the leaflets of the mitral valve fail to close properly.

	eMedicine - Mitral Stenosis, Congenital : Article Excerpt by: M Silvana Horenstein, MD (Site not responding. Last check: 2007-10-23)
		The normal mitral valve is a complex apparatus composed of an annulus and two leaflets that are attached by chordae tendineae to two papillary muscles.
		The papillary muscles arise from the walls of the LV and secure the chordae and mitral leaflets, preventing prolapse of the valve during ventricular systole.
		Mortality/Morbidity: In congenital MS in the fetus, mitral valve obstruction does not interfere with normal growth and development, even if the mitral valve is atretic, because the amount of pulmonary venous return to the left atrium is small and the fetal bronchocollateral circulation is adequate to relieve the obstructive effects.

	Mitral Valve Stenosis
		Mitral valve stenosis is a "quiet" condition—it often has no symptoms in its early stages and may not be diagnosed until you've had the disease for some time.
		Echocardiography should be considered if the doctor suspects mitral valve stenosis, whether or not symptoms are present, or if you have associated conditions such as heart failure or atrial fibrillation.
		A chest X-ray may show evidence of mitral valve stenosis, such as enlargement of the upper left heart chamber (left atrium), enlargement of the pulmonary arteries, and too much blood and backup of fluid in the lungs (pulmonary edema).

	Congenital Heart Disease in Adults
		Supravalvar mitral ring is a rare congenital heart defect, of surgical importance, characterized by an abnormal ridge of connective tissue on the atrial side of the mitral valve.
		Supravalvar mitral ring is a circumferential ridge or membrane arising from the left atrial wall overlying the mitral valve and frequently attached to the mitral valve annulus.
		The mitral valve itself often is abnormal and stenotic at the valvar or subvalvar level with fusion of leaflets, small valve orifice, and abnormal papillary muscles being common abnormalities.

		The difference between the electrocardiographic abnormalities produced by congenital heart disease, such as pulmonary valve stenosis (A), and those produced by the early stages of acquired disease, such as mitral stenosis (B).
		This type of abnormality occurs with congenital disease, such as pulmonary valve stenosis, or advanced acquired disease, such as mitral stenosis with moderately severe pulmonary hypertension.
		Early in the natural history of right ventricular hypertrophy due to acquired heart disease, such as mitral stenosis or primary pulmonary hypertension, the mean QRS vector tends to have an intermediate or vertical direction; it usually retains a slightly posterior direction.

		Mitral stenosis (mitral valve stenosis) is a narrowing of the mitral valve opening that increases resistance to blood flow from the left atrium to the left ventricle.
		Mitral stenosis almost always results from rheumatic fever, a childhood illness that sometimes occurs after untreated strep throat or scarlet fever (see Bacterial Infections: Rheumatic Fever).
		If mitral stenosis is severe, pressure increases in the left atrium and in the veins of the lungs, resulting in heart failure with fluid accumulation in the lungs.

		The congenital malformation of the mitral valve is rather unusual and consists of stenosis of the valve, mitral insufficiency or a combination of both.
		Other congenitals which can be occasionally seen in association with mitral valve disease are aortic stenosis, coarctation of the aorta and patent ductus arteriosus.

		Mitral stenosis is a heart valve disorder that affects about 2 out of 10,000 people.
		It most commonly occurs in people who have had rheumatic fever, but because the incidence of rheumatic fever is decreasing in the United States, the incidence of mitral stenosis is also decreasing.
		Narrowing of the mitral valve prevents the valve from opening properly and obstructs the blood flow from the left atrium to the left ventricle.

	Balloon Mitral Valvuloplasty Effectively Relieves Severe Congenital Mitral Stenosis
		By Sahar Bedrood B.S. and Asher Kimchi M.D. Boston, MA- Congenital mitral stenosis (MS) is a rare condition that is often associated with left heart obstructions.
		The goal of BMVP for children with congenital MS is to reduce left ventricular inflow obstruction and left atrial pressure, thereby relieving symptoms and delaying MVR until the patient is older.
		Overall, the procedural mortality of BMVP is uncommon and is an effective means of relieving left ventricular obstruction in congenital MS.

		Surgical repair of congenital mitral stenosis (MS) is still a challenge.
		The mechanism of MS was commissure to papillary muscle fusion (n=11), supravalvar mitral ring (n=5), parachute mitral valve (n=3) and excess leaflet tissue (n=1).
		Congenital MS can be repaired with very significant relief of the gradient in most patients.

		You mentioned that mitral stenosis is NOT repairable and always requires a replacement.
		I have (or had) congenital mitral stenosis and just recently had a very succesful repair.
		Rheumatic mitral stenosis is currently NOT repairable, and given this is the more common cause then congenital MS, I can see how this all confused you.

		These “touch-free” techniques can be applied to all forms of congenital heart disease and, because of limited exposure between the surgeon’s hand and heart tissue, have extremely low infection rates (less than 1%).
		With neonates excluded, almost all patients (children and adults) undergoing touch-free congenital heart surgery at California Pacific have had their breathing tubes removed in the operating room prior to intensive care transfer.
		Frequently associated with anatomical aberrations of the heart’s left side, congenital mitral valve stenosis is difficult to treat and, in children, frequently requires a prosthetic valve.
