Discrete subvalvular aortic stenosis is a progressive lesion. Most reported cases have had a measurable left ventricular. aortic gradient that progressed in severity. This report describes 35 patients in whom no significant left ventricular-aortic ob

Low-gradient severe aortic stenosis (LGSAS) with preserved ejection fraction (EF) is incompletely understood. The influence of arterial afterload and diastolic dysfunction on the hemodynamic presentation of LGSAS remains unknown.The authors sought to

ObjectivesValve hemodynamics and clinical outcomes among patients with a small aortic annulus who underwent transcatheter aortic valve implantation (TAVI) were examined.BackgroundThe presence of a small aortic annulus may complicate the surgical mana

The natural history of severe, symptomatic aortic stenosis has been well documented. However, the natural history of moderate aortic stenosis remains poorly understood. Therefore, a group of 66 patients was identified who had a diagnosis of moderate

In patients with mitral stenosis, routine noninvasive techniques are insensitive for the detection of coexistent aortic insufficiency. The ability of pulsed Doppler echocardiography to detect the presence or absence of angiographically demonstrated a

Objectives. This exercise study assessed the relation between valvular resistance and flow in patients with mitral stenosis. Background. Valvular resistance has been proposed as an alternative measue of stenotic valvular lesions, which is speculated

Estimation of the orifice area is of major importance in the timing of valve dilation or surgery in patients with mitral stenosis. Determination of the area has traditionally been accomplished at cardiac catheterization by the Gorlin equation. The va
