OBJECTIVES.: We attempted to determine the accuracy and pitfalls of calculating the mitral
regurgitant orifice area with the proximal isovelocity surface area method in a clinical series …

To compare transthoracic and transesophageal echocardiography in the clinical
assessment of left-sided valvular regurgitation, 118 patients who underwent both …

Accurate quantitation of mitral regurgitation (MR) severity is clinically important, especially in
the present era of mitral valve repair. 1 Myxomatous degeneration has become the leading …

Several noninvasive techniques, including radionuclide angiography and Doppler
echocardiography, have attempted to measure the regurgitant volume in patients with mitral …

This study reports the role of Doppler ultrasound during exercise for assessment of patients
with mitral stenosis. Doppler echocardiography was performed at rest and during symptom …

Mitral valve area determined by the Gorlin formula in patients with combined mitral stenosis
and regurgitation underestimates the true orifice size. Recent data suggest Doppler …

Forty-eight patients with mitral regurgitation were studied by echocardiography to establish
differential diagnostic features. Six patients with rheumatic mitral insufficiency manifested …

To determine objective predictors of survival, 53 patients with chronic, hemodynamically
severe mitral regurgitation underwent rest and exercise radionuclide cineangiography …

We studied 16 patients with chronic aortic insufficiency to compare a method for measuring
regurgitant volume with color Doppler flow mapping to stroke count ratio determined by …

M-mode and Doppler echocardiography were performed in 16 patients with first degree
atrioventricular (AV) block, 1 patient with second degree (Werickebach type) and 3 patierits …
