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.

tricuspid regurgitation (TR)

Etymology: Gk, treis, three; L, cuspis, point + re, gurgitare, again to flow back
the backflow of blood from the right ventricle into the right atrium, resulting from imperfect functioning (insufficiency) of the tricuspid valve.

tricuspid regurgitation

Tricuspid insufficiency Cardiology Backflow of blood from the right ventricle to the right atrium during right ventricular contraction, due to damage to the tricuspid valve, right ventricular enlargement, rheumatic fever

tricuspid

having three points or cusps, as a valve of the heart.

tricuspid dysplasia
a congenital defect of the tricuspid heart valve commonest in cats. There is a variety of forms of the defect which causes enlargement of the right atrium and ventricle. See also ebstein's anomaly.
tricuspid insufficiency
a functional incompetence that may be caused by rupture of the chordae tendineae of the tricuspid valve, bacterial endocarditis, heartworms, endocardiosis or congenital anomalies, resulting in regurgitation of blood from the right ventricle into the right atrium during systole.
tricuspid regurgitation
see tricuspid insufficiency (above).
tricuspid valve
the valve located between the right atrium and right ventricle. Called also right atrioventricular valve.
