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.
