Background—The decay of the pressure gradient across a stenotic mitral valve is
determined by the size of the orifice and net AV compliance (Cn). We have observed a …

OBJECTIVES.: This study sought to compare the mitral valve areas of patients with
rheumatic mitral valve stenoses as determined by means of four echocardiographic and …

BACKGROUND: Doppler-derived hemodynamic data for normal tricuspid valve
bioprostheses are limited. METHODS: A comprehensive retrospective Doppler …

OBJECTIVES This study was performed to determine the feasibility, accuracy and
reproducibility of real-time volumetric three-dimensional echocardiography (3-D echo) for …

Background Recent studies have shown that many instrument and physiological factors limit
the ability of color Doppler total jet area within the receiving chamber to predict the severity …

Opinion statement Mitral valve disease (MVD) related to mitral valve prolapse (MVP),
coronary artery disease (CAD), and calcific mitral stenosis, is increasing in prevalence …

Quantitation of valvular regurgitation remains an important goal in clinical cardiology. It has
been described previously that with the use of color Doppler flow mapping, simple …

The accuracy of measurements of mitral valve orifice area (MVA) from three-dimensional
echocardiographic (3DE) image data sets obtained by a transthoracic or transesophageal …

Recent studies have shown good agreement between proximal regurgitant jet size obtained
with transthoracic color flow mapping and regurgitant fraction in patients with mitral …

Mitral stenosis (MS) is characterized by pathologic thickening and narrowing of the valve,
resulting in a reduction in the valve orifice area. This process results in obstruction to …
