Mitra Health Dictionary

The mitral valve, so-called because of its resemblance to a bishop’s mitre, is the valve which guards the opening between the ATRIUM and VENTRICLE on the left side of the HEART.... mitral valve

A defect in the MITRAL VALVE of the HEART which allows blood to leak from the left VENTRICLE into the left ATRIUM. It is also known as mitral regurgitation; incompetence may occur along with MITRAL STENOSIS. The left ventricle has to work harder to compensate for the faulty valve, so it enlarges, but eventually the ventricle cannot cope with the extra load and left-sided heart failure may develop. A common cause of mitral incompetence is RHEUMATIC FEVER or damage following a heart attack. The condition is treated with drugs to help the heart, but in severe cases heart surgery may be required.... mitral incompetence

Narrowing of the opening between the left ATRIUM and left VENTRICLE of the HEART as a result of rigidity of, and adhesion between, the cusps of the MITRAL VALVE. It is due, almost invariably, to the infection RHEUMATIC FEVER. The atrium has to work harder to force blood through the narrowed channel. The effects are similar to those of MITRAL INCOMPETENCE. Shortness of breath and palpitations and irregular beating (?brillation) of the atrium are common consequences in adults. Drug treatment with DIGOXIN and DIURETICS helps, but surgery to dilate or replace the faulty valve may be necessary.... mitral stenosis

(Roxb.) Korth.

Family: Rubiaceae.

Habitat: All over India, and up to 1,200 m in the outer Himalaya.

English: Kaim.

Ayurvedic: Giri-kadamba, Kadamba (var.).

Siddha: Chinna-Kadambu.

Action: Bark—used for muscular pain. Bark and root—febrifuge, antispasmodic.

Both indole and oxindole alkaloids have been isolated from the plant. (The composition of alkaloids varies with season and from place to place.) The main indole alkaloid reported is akuammigine and oxindole alkaloids have been identified as mitra- phylline, isomitraphylline, pteropo- dine, isopteropodine, speciophylline and uncarine F. Anthocephalus cadamba Miq. is the accepted source of Kadamba.... mitragyna parvifolia

Backflow of blood from the left ventricle of the heart (pumping arterial blood outwards to the aorta) into the left atrium (receiving oxygenated blood from the lungs) because of faulty closure of the mitral (bicuspid) valve that guards between the two chambers.... regurgitations, mitral

A serious defect of the mitral valve of the heart. Two kinds: (1) a permanently deformed narrowed valve (mitral stenosis), or (2) a dilated, over-stretched or distorted valve through enlargement of the left ventricle. In this case imperfect closure causes back pressure which produces chest symptoms. Incompetence leads to enlargement of the heart. Often a legacy from rheumatic fever in children. Sooner or later the liver congests with possible jaundice. Presence of albumin in the urine follows kidney involvement.

Treatment. See: HEART – LEFT VENTRICULAR FAILURE. ... mitral disease

A common, slight deformity of the mitral valve, in the left side of the heart, that can produce a degree of mitral incompetence. The prolapse is most common in women and causes a heart murmur. It may be inherited, but the cause is often unknown.Usually, there are no symptoms, and treatment is not needed. Occasionally, the condition may produce chest pain, arrhythmia, or, rarely, heart failure. Often, no treatment is required for mitral valve prolapse, but some people may be treated with beta-blocker drugs, diuretic drugs, antiarrhythmic drugs, or, rarely, heart-valve surgery.... mitral valve prolapse

(mitral incompetence) failure of the *mitral valve to close, allowing a reflux of blood from the left ventricle of the heart to the left atrium. It may be due to mitral valve prolapse (MVP) in which one or both valve leaflets flop back into the left atrium (also known as ‘floppy mitral valve’). It also results from chronic rheumatic scarring of the valve, or is secondary to left ventricular muscle damage. Its manifestations include breathlessness, atrial *fibrillation, embolism, enlargement of the left ventricle, and a systolic *murmur. Mild cases are symptomless and require no treatment, but in severe cases the affected valve should be repaired or replaced with an artificial one (mitral prosthesis).... mitral regurgitation
