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.

a·or·tic re·gur·gi·ta·tion

reflux of blood through an incompetent aortic valve into the left ventricle during ventricular diastole.
Synonym(s): Corrigan disease

aortic regurgitation

n.
The backward flow of blood from the aorta into the left ventricle caused by incompetent closure of the aortic valve. Also called aortic insufficiency.

aortic insufficiency

The reflow of blood back from the aorta into the left ventricle due to incompetency of the aortic valve.
 
Clinical findings
Dyspnoea on exertion, orthopnea, fatigue, ± angina, increased pulse pressure, systolic hypertension with increased afterload on left ventricle.
 
Aetiology
Congenital or acquired valve defect of either the aortic leaflets (infectious endocarditis, rheumatic fever) or the aortic root (annuloaortic ectasia, Marfan syndrome, aortic dissection, collagen vascular disease, syphilis).
 
Examination
Increased pulse pressure (Corrigan’s pulse, Hill sign, Musset sign, Quincke’s pulse), systolic murmur, diastolic rumble (Austin Flint murmur over cardiac apex).
 
Workup
Doppler echocardiography to estimate severity of AR, confirmed by aortography.
 
Management
Early valve replacement surgery, guided by the ‘55 rule’—i.e., performed when the ejection fraction is < 55% and/or the end-systolic dimension = 55 mm.

Reflux of blood through an incompetent aortic valve into the left ventricle during ventricular diastole.

aortic regurgitation

Abnormal back flow of blood from the aorta through the aortic valve. In developing countries the valvular defect is mainly due to as complication of rheumatic fever; in Western countries the defect is usually congenital.

Corrigan,

Sir Dominic John, Irish pathologist and clinician, 1802-1880.
Corrigan disease - reflux of blood through an incompetent aortic valve into the left ventricle during ventricular diastole. Synonym(s): aortic regurgitation
Corrigan pulse - the collapsing or water-hammer-type pulse in aortic regurgitation or peripheral arterial dilation, characterized by an abrupt rise and rapid fall away.

Secondly, because of its association with aortic valve prolapse and aortic regurgitation (AR) which is estimated to exceed 40%.2
Among multivalvular lesions, mitral regurgitation, mitral stenosis and aortic regurgitation was the commonest combination.
Use of a relatively large occluder caused traction on the aortic annulus, resulting in increased aortic regurgitation. If the diameter of the RSVA defect exceeds 10 mm, we recommend surgical treatment rather than transcatheter closure.
The valve had four leaflets or cusps instead of the normal three-leaflet configuration and had associated mild to moderate aortic regurgitation, they added--which closely resembled, according to them, the outline of a four-leafed clover.
A transthoracic echocardiogram was done which showed biatrial dilatation, right ventricular dilatation, slightly decreased left ventricular systolic function, severe aortic regurgitation, a possible bicuspid aortic valve with vegetation, an enlarged aortic root, severe tricuspid regurgitation with moderate to severe pulmonary hypertension, tricuspid valve vegetation, a possible non coronary sinus of Valsalva aneurysm with perforation to the right atrium and severe coarctation at the aortic isthmus with a maximum peak gradient of 77 mmHg (Figure 1).
One of the six also had aortic dilatation, a bicuspid aortic valve, and aortic regurgitation.
She was asymptomatic until the 4th month of pregnancy when she began with tachycardia and exertional dyspnea which rapidly evolved to rest dyspnea; she was admitted to the hospital, and an echocardiographic study was performed, showing a very severe aortic regurgitation and a 5.5 cm aneurysm of the root and ascending aorta; the left ventricle was markedly dilated with a borderline ventricular fraction.
Objectives: To evaluate the frequency of early remodeling in patients of severe aortic regurgitation after aortic valve replacement and to see the incidence of early remodeling in patients with stroke volume >97 ml versus 97 ml in whom Remodeling occurred where as in patients with stroke volume 97 ml is a good predictor of early LV remodeling.
Claudication (38%-81%), Carotidynia or vessel tenderness (13%-32%), Hypertension (28%-53%) (58% with renal artery stenosis in one series), Aortic regurgitation (20%-24%), Raynaud's syndrome (15%).
No obstruction of coronary artery ostia occurred, and no moderate to severe aortic regurgitation was observed.
