OBJECTIVE: In animal models of aortic insufficiency, the right common carotid artery is typically used to damage valve leaflets; this strategy impedes subsequent assessments of left ventricular hemodynamics. The present study aimed to establish an alternative technique that would allow subsequent left ventricular catheterization to monitor sequential hemodynamics in rats with aortic insufficien...

BACKGROUND The purpose of this study was to investigate the genesis of the Austin Flint murmur using Doppler and echocardiographic imaging. METHODS AND RESULTS A total of 51 patients having significant aortic insufficiency and an anatomically normal mitral valve were evaluated. They were divided into two groups; 30 patients had an audible Austin Flint murmur (AFM+) and 21 did not (AFM-). All ...

The dominance of the coronary arterial system was determined angiographically in 75 adult patients with isolated aortic stenosis with or without insufficiency, 25 adult patients with pure aortic insufficiency, 51 adult patients with combined aortic stenosis and mitral valve disease, and 44 children with bicuspid aortic valves. There was an unusually high incidence of left dominance in adults wi...

A 33-year-old man presented with severe aortic insufficiency due to a prolapsed bicuspid aortic valve. The ventriculoaortic junction was dilated to 29 mm without root dilatation, and external ring annuloplasty was performed using a Gelweave (Terumo, Tokyo, Japan) graft to reduce the size to 22 mm. The leaflets were repaired by dividing and suturing a raphe between the right and left cusps. This...

The following paper (lescribes the results of electrokymographic studies performed on patients vith l)roved aortic insufficiency. Alterations in the shape of the aortic ejection curve were found and were accompanied by a diminution or absence of the incisura in the presence of insufficiency of the aortic valves. Alterations in heart border motion of the ventricles Xwere also found. The possible...

Takayasu's arteritis (TA) is a granulomatous vasculitis of medium and large arteries, which most often presents as pulseless disease due to widespread arterial stenoses. Only the minority of TA patients have aortic valve insufficiency, which is due to aortic root dilatation following aortitis and aneurysm formation. No other cardiac valve is involved. We report a case of Takayasu's disease-rela...
