mitral insufficiency

insufficiency /in·suf·fi·cien·cy/ (-sah-fish´in-se) inability to perform properly an allotted function.

---

adrenal insufficiency 

1. hypoadrenalism; abnormally diminished activity of the adrenal gland.

2. adrenocortical i.

adrenocortical insufficiency  abnormally diminished secretion of corticosteroids by the adrenal cortex, as in Addison's disease.

aortic insufficiency  defective functioning of the aortic valve, with incomplete closure resulting in aortic regurgitation.

cardiac insufficiency  heart failure.

coronary insufficiency  decrease in flow of blood through the coronary blood vessels.

insufficiency of the externi  deficient power in the externi muscles of the eye, resulting in esophoria.

ileocecal insufficiency  inability of the ileocecal valve to prevent backflow of contents from the cecum into the ileum.

insufficiency of the interni  deficient power in the interni muscles of the eye, resulting in exophoria.

mitral insufficiency  defective functioning of the mitral valve, with incomplete closure causing mitral regurgitation.

pulmonary insufficiency  defective functioning of the pulmonary valve, with incomplete closure causing pulmonic regurgitation.

thyroid insufficiency  hypothyroidism.

tricuspid insufficiency  defective functioning of the tricuspid valve, with incomplete closure causing tricuspid regurgitation; it is usually secondary to systolic overload.

valvular insufficiency 

1. dysfunction of a cardiac valve, with incomplete closure resulting in valvular regurgitation; named for the valve involved.

2. venous i.

velopharyngeal insufficiency  failure of velopharyngeal closure due to cleft palate, muscular dysfunction, etc., resulting in defective speech.

venous insufficiency  inadequacy of the venous valves with impairment of venous drainage, resulting in edema.

vertebrobasilar insufficiency  transient ischemia of the brain stem and cerebellum due to stenosis of the vertebral or basilar artery.

mitral insufficiency

n. Abbr. MI

Incompetence of the mitral valve of the heart resulting in backflow of blood from the left ventricle to the left atrium. Also called mitral regurgitation.

---

mitral insufficiency.

See mitral regurgitation.

---

mitral

shaped like a miter; pertaining to the mitral valve.

---

mitral area

that area of the thoracic wall through which sounds of the mitral valve can best be auscultated; generally the lower one-third of the mid- to anterior left thorax.

mitral atresia-hypoplastic left heart syndrome

defects in the development of the mitral valve, left heart and aortic valve, which occur rarely in cats.

mitral complex

includes the leaflets, annulus, chordae tendineae and papillary muscles of the mitral valve, left atrium and left ventricular muscle wall.

mitral insufficiency

a functional incompetence resulting in regurgitation of blood from the left ventricle to the left atrium during systole or from the great vessels into the left atrium during diastole.

mitral regurgitation

see mitral insufficiency (above).

mitral valve

the left atrioventricular valve, the valve between the left atrium and the left ventricle of the heart; it is composed of two cusps, anterior and posterior. Called also the bicuspid valve.

mitral valve prolapse (MVP)

a condition in which some portion of the mitral valve is pushed back too far during ventricular contraction. Often a complication of mitral endocardiosis.

Patient discussion about mitral insufficiency.

Q. what do you do with a broken heart? I HAD A ECHO DONE THIS WEEK AND CONCLUSION WAS: 1)SEVERE MIRTAL REGURGITATION WITH LEFT ATRIAL DILATATION 2)LOW NORMAL LV FUNCTION CHEST X RAY IMPRESSION WAS: 1)NORMAL SIZE HEART WITH PROMINENT LEFT HEART BORDER. 2)PROMINENT MARKINGS WITH PROMINENT CHANGES. 3)THE BONES ARE OSTEOPENIC. BLOOD TEST....CHEMISTRY B TYPE NATRIURETIC PEPTIDE HIGH 260

A. The left atrial dilatation is likely the cause of the elevated beta natriuretic peptide. A cardiologist should be able to talk with you about dealing with the mitral valve regurgitation.
