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.

(val'vyū-lăr rĕ-gŭr'ji-tā'shŭn)
A leaky state of one or more of the cardiac valves, in which the valve does not close tightly and blood therefore regurgitates through it.

These post-operative changes have been reported to pulmonary insufficiency, pre- operative hypoxia and ventriculotomy.17,23,24 CMR and radionuclide ventriculography are choice methods for assessment of the ventricular function; also, they are expensive and prolonged in duration.19,25,27
The autopsy report indicated that she suffered from congestive heart failure, arthritis, and chronic obstructive pulmonary disease, and that death was caused by pulmonary insufficiency brought about by exposure to excessive heat.
The condition may result in pulmonary insufficiency if the diagnosis or treatment is delayed.13-5
The findings on en Echocardiography included aortic valve stenosis [70 mmHg gradient], Patent Ductus Arteriosus [2.5 mm of thickness, with L-R shunt], Pulmonary Hypertension, 2nd degree tricuspid insufficiency, 1st degree pulmonary insufficiency, 1st degree mitral insufficiency, and mild stenosis in the left branch of the pulmonary artery.
