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.

re·gur·gi·ta·tion

(rē-gŭr'ji-tā'shŭn),
1. A backward flow, as of blood through an incompetent valve of the heart.
2. The return of gas or small amounts of food from the stomach.
[L. regurgitatio (see regurgitate)]

regurgitation

/re·gur·gi·ta·tion/ (re-ger″jĭ-ta´shun)
1. flow in the opposite direction from normal.

aortic regurgitation  (AR) backflow of blood from the aorta into the left ventricle due to insufficiency of the aortic semilunar valve.
mitral regurgitation  (MR) backflow of blood from the left ventricle into the left atrium due to insufficiency of the mitral valve.
pulmonic regurgitation  (PR) backflow of blood from the pulmonary artery into the right ventricle due to insufficiency of the pulmonic semilunar valve.
tricuspid regurgitation  (TR) the backflow of blood from the right ventricle into the right atrium due to insufficiency of the tricuspid valve.
valvular regurgitation  backflow of blood through the orifices of the heart valves due to imperfect closing of the valves.

regurgitation

[rēgur′jitā′shən]
Etymology: L, re, again, gurgitare, to flow back
1 the backward flow from the normal direction, as the return of swallowed food into the mouth.
2 the backward flow of blood through a defective heart valve, named for the affected valve, as in aortic regurgitation. See also reflux.

regurgitation

Cardiology The backflow of blood across an incompetent valve. See Aortic regurgitation, Mitral regurgitation. Cf GERD, Reflux.

re·gur·gi·ta·tion

(rē-gŭr'ji-tā'shŭn)
1. A backward flow, as of blood through an incompetent valve of the heart.
2. Synonym(s): vomiting.

2. Return of gas or small amounts of food from the stomach.
[L. regurgitatio]

regurgitation (rēgur´jitā´shən),

n a backward flowing (e.g., casting up of undigested food, backward flowing of blood into the heart or between the chambers of the heart).
regurgitation, heart valve,
n blood flow in the wrong direction (from a ventricle to an atrium or into the heart from an artery) through a valve that has failed to close completely. See also heart valves.

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.

Patient discussion about regurgitation

Q. what do you do with a broken heart? I HAD A ECHO DONE THIS WEEK AND CONCLUSION WAS: 1)SEVERE MIRTAL REGURGITATION WITH LEFT ATRIAL DILATATION 2)LOW NORMAL LV FUNCTION CHEST X RAY IMPRESSION WAS: 1)NORMAL SIZE HEART WITH PROMINENT LEFT HEART BORDER. 2)PROMINENT MARKINGS WITH PROMINENT CHANGES. 3)THE BONES ARE OSTEOPENIC. BLOOD TEST....CHEMISTRY B TYPE NATRIURETIC PEPTIDE HIGH 260

A. The left atrial dilatation is likely the cause of the elevated beta natriuretic peptide. A cardiologist should be able to talk with you about dealing with the mitral valve regurgitation.
