regurgitation

 [re-ger″jĭ-ta´shun]
1. a backward flowing; see also backflow and reflux.
aortic regurgitation backflow of blood from the aorta into the left ventricle, owing to insufficiency of the aortic valve; it may be chronic or acute.
mitral regurgitation backflow of blood from the left ventricle into the left atrium, owing to insufficiency of the mitral valve; it may be acute or chronic, and is usually due to mitral valve prolapse, rheumatic heart disease, or a complication of cardiac dilatation.
pulmonic regurgitation backflow of blood from the pulmonary artery into the right ventricle, owing to insufficiency of the pulmonic valve.
tricuspid regurgitation backflow of blood from the right ventricle into the right atrium, owing to imperfect functioning (insufficiency) of the tricuspid valve.
valvular regurgitation backflow of blood through the orifice of one of the heart valves owing to imperfect closing of the valve (valvular insufficiency); see aortic, mitral, pulmonic, and tricuspid regurgitation.

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.

valvular regurgitation

Etymology: L, valva, folding door, re + gurgitare, to flow
a backflow of blood that occurs when the heart contracts but a heart valve fails to close properly.

val·vu·lar re·gur·gi·ta·tion

(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.
Synonym(s): valvular insufficiency.

valvular regurgitation (valˑ·vy·lr rē·gurˈ·ji·tāˑ·shn),

n the backflow of blood during contraction of the heart; caused by a defective heart valve.

regurgitation

a backward flowing, as the casting up of undigested food, or the backflow of blood through a defective heart valve. In the alimentary canal the regurgitation of food comes from the esophagus, as distinct from vomiting in which the food comes from the stomach. A sign of pyloric obstruction or megaesophagus.

regurgitation cycle
see reticular cycle.
neurotic regurgitation
regurgitation by budgerigars is a common phenomenon with no physiological explanation and is considered to be an expression of affection.
valvular regurgitation
backflow of blood through the orifices of the heart valves owing to imperfect closing of the valves (valvular insufficiency); named, according to the valve affected, aortic, mitral, pulmonic or tricuspid regurgitation.
