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 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.

val·vu·lar re·gur·gi·ta·tion

a leaky state of one or more of the cardiac valves, in which the valve not closing tightly and blood is therefore regurgitating through it.

tricuspid insufficiency

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

(val'vyū-lăr rĕ-gŭr'ji-tā'shŭn)

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.

While right ventricular dysfunction and tricuspid insufficiency develops in elderly patients, degree of left to right shunt may decrease.

The ones defending the bicaval technique informed that the atrium geometry became unbalanced, the contractions of two atrium parts coincided and this could cause tricuspid insufficiency in the postoperative early period.
