tricuspid 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.

tricuspid insufficiency

n.

Valvular insufficiency involving the tricuspid valve.

tricuspid insufficiency,

incomplete closure of the tricuspid valve, resulting in tricuspid regurgitation.

insufficiency [in″sŭ-fish´en-se]

inability to perform properly an allotted function; called also incompetence.

adrenal insufficiency abnormally diminished activity of the adrenal gland; called also hypoadrenalism.

adrenocortical insufficiency abnormally diminished secretion of corticosteroids by the adrenal cortex; see also addison's disease. Called also hypoadrenocorticism and hypocorticism.

aortic insufficiency inadequate closure of the aortic valve, permitting aortic regurgitation.

coronary insufficiency decreased supply of blood to the myocardium resulting from constriction or obstruction of the coronary arteries, but not accompanied by necrosis of the myocardial cells. Called also myocardial ischemia.

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

mitral insufficiency inadequate closure of the mitral valve, permitting mitral regurgitation.

placental insufficiency dysfunction of the placenta, with reduction in the area of exchange of nutrients; it often leads to fetal growth retardation.

pulmonary insufficiency

1. pulmonary valve insufficiency.

2. respiratory insufficiency.

pulmonary valve insufficiency inadequate closure of the pulmonary valve, permitting pulmonic regurgitation.

respiratory insufficiency see respiratory insufficiency.

thyroid insufficiency hypothyroidism.

tricuspid insufficiency incomplete closure of the tricuspid valve, resulting in tricuspid regurgitation.

valvular insufficiency failure of a cardiac valve to close perfectly, causing valvular regurgitation; see also aortic, mitral, pulmonary, and tricuspid insufficiency.

velopharyngeal insufficiency inadequate velopharyngeal closure, due to a condition such as cleft palate or muscular dysfunction, resulting in defective speech.

venous insufficiency inadequacy of the venous valves and impairment of venous return from the lower limbs (venous stasis), often with edema and sometimes with stasis ulcers at the ankle.

tricuspid

having three points or cusps, as a valve of the heart.

tricuspid dysplasia

a congenital defect of the tricuspid heart valve commonest in cats. There is a variety of forms of the defect which causes enlargement of the right atrium and ventricle. See also ebstein's anomaly.

tricuspid insufficiency

a functional incompetence that may be caused by rupture of the chordae tendineae of the tricuspid valve, bacterial endocarditis, heartworms, endocardiosis or congenital anomalies, resulting in regurgitation of blood from the right ventricle into the right atrium during systole.

tricuspid regurgitation

see tricuspid insufficiency (above).

tricuspid valve

the valve located between the right atrium and right ventricle. Called also right atrioventricular valve.
