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.

Causes of CHF are numerous and can include valvular insufficiency, congenital disease, hypertension, myocarditis, dilated cardiomyopathy, neoplasia, arrhythmias, and hypertrophic cardiomyopathy.
Twenty-four women ages 30-63 with no previous history of cardiovascular disease presented with new onset severe heart valve deformity and valvular insufficiency. Eight of these women also suffered from new onset pulmonary hypertension and five required cardiac surgery (Connolly et al., 1997).
The AHA recommends EP in MVP patients with valvular insufficiency, or regurgitation, but has noted that definitive data are particularly limited.[1] Men and patients older than 45 years with MVP also appear at greater risk for infective endocarditis.[6]
In spite of prior lack of clinical symptoms, patients with acquired rheumatic heart disease, consisting mainly in stenosis of mitral and aortic valve, run a high risk of developing pulmonary edema, where as the patients with asymptomatic valvular insufficiency tend to tolerate volumetric overload during pregnancy much better.6
individuals, which leads us to believe that obesity in and of itself is a contributor to chronic venous disease in the absence of valvular insufficiency,," Dr.
The other limitations of this study are that the patients have wide age range and the duration of valvular insufficiency was not taken into consideration in this study, because duration of valvular insufficiency affects both echocardiographic and radiological cardiac dimensions.
Of the 46 patients who did so, some degree of valvular insufficiency was identified in 41, or 89%.
In conclusion, rheumatic heart disease particularly affects left heart valves, and duration and severity of valvular insufficiency affects both echocardiographic and radiological cardiac dimensions.
