We evaluated 147 patients with adequate color Doppler and angiographic studies for mitral
regurgitation. Sixty-five patients had no mitral regurgitation by both color Doppler and …

Degenerative mitral valve disease is responsible for the syndromes of billowing mitral
leaflet, mitral valve prolapse (MVP), floppy mitral valve, and flail leaflet. 1– 6 The pathology …

Noninvasive imaging currently plays an important role in the diagnosis and evaluation of
patients with valvular heart disease. Doppler echocardiography provides the clinician with a …

We tested the hypotheses that Doppler echocardiography has a higher accuracy than
clinical evaluation in the detection of significant aortic and mitral valvular heart disease and …

The spatial distribution of simulated regurgitant jets imaged by Doppler color flow mapping
was evaluated under constant flow and pulsatile flow conditions. Jets were simulated …

To determine whether Doppler color flow mapping could be used to quantify changing levels
of regurgitant flow and define the technical variables that influence the size of color flow …

A noninvasive method to accurately quantitate the severity of mitral insufficiency would be of
major clinical value. In theory, in the absence of confounding variables, regurgitant mitral …

Magnetic resonance imaging that uses shallow flip angles, short repetition times, and
gradient refocused echoes results in multiple images throughout the cardiac cycle in which …

To establish the etiology of strokes related to the anticardiolipin antibody (Acla) syndrome
and to determine the relationship of valvular heart disease and stroke in the presence of the …

Regurgitant jet dimensions imaged by color Doppler flow mapping have been used to
evaluate the severity of valvular insufficiency in clinical studies. To study the effect of …
