Sudden, Severe Aortic Insufficiency

Sudden, severe aortic insufficiency.

THE experimental production of sudden, severe aortic insufficiency causes left ven-tricular diastolic pressure to become markedly elevated so that it exceeds left atrial pressure and results in diastolic closure of the mitral valve.' Ten cases of severe aortic insuffi-ciency have been reported in which left ven-tricular pressure exceeded left atrial pressure during diastole, causing premature m...

ANTIPHOSPHOLIPID ANTIBODY SYNDROME-A CASE OF AORTIC VALVE INSUFFICIENCY

A 31 year old woman was hospitalized for evaluation of aortic valve insufficiency and her present cardiac status. Clinical and paraclinical findings strongly suggested the presence of a collagen vascular inflammatory processprecisely, the antiphospholipid antibody syndrome (APS), with systemic lupus erythematosus as the underlying disease.

Severe aortic insufficiency associated with left ventricular dysfunction and aortic coarctation.

Can J Surg, Vol. 45, No. 3, June 2002 213 P congenital coarctation of the aorta associated with severe aortic insufficiency and left ventricular failure is unusual in adults. Such a life-threatening situation deserves special consideration. Patient improvement depends on an emergent aortic valve replacement and normalization of peripheral vascular resistance in order to decrease cardiac workloa...

Association of aortic and main left coronary aneurysms with severe aortic insufficiency in Takayasu’s arteritis

Takayasu's arteritis is a granulomatous vasculitis of unknown etiology that affects mainly the aorta and its branches. As a result of intimal fibroproliferation, segmental stenosis, occlusion, dilatation, and aneurysmal formation of the involved vessels may develop. It is an uncommon disease and usually affects young Asian female patients during the second and third decades of life. Coronary ar...
