We prospectively assessed the influence of aging on the prevalence of valvular regurgitation
by using color flow imaging. One hundred eighteen healthy volunteers (21 to 82 years old) …

Recent studies have attempted to predict the severity of regurgitant lesions from jet size on
Doppler flow maps. Jet size is a function of both regurgitant volume and fluid entrained from …

Color-coded Doppler echocardiography permits visualization of the spatial distribution of
flow velocities produced by valvular regurgitation with a high sensitivity. 1 Doppler color flow …

The noninvasive Doppler assessment of regurgitant volume from jet size is limited by the
fundamental inequality of jet volume and regurgitant volume and by the dependence of jet …

Dilated cardiomyopathy and coronary-induced heart failure may be clinically
indistinguishable. By definition the etiology of dilated cardiomyopathy is unknown, 1 …

The accuracy of the thermodilution cardiac output technique in the presence of tricuspid
regurgitation (TR) has been challenged. 1 TR is common in patients with advanced …

This study was performed to examine the effectiveness of color Doppler imaging (CDI) in
demonstrating the neonatal intracranial vessels and altered intracranial flow patterns and to …

Few data exist regarding the relationship of valvular anatomy and coaptation to the
presence of mitral regurgitation (MR) in patients with mitral valve prolapse (MVP). Therefore …

To evaluate the usefulness of the Doppler‐derived effective orifice area (EOA) in assessing
the hemodynamic severity of subaortic stenosis (SAS) in dogs, 2‐dimensional and Doppler …

The most common objective assessments of mitral regurgitation are limited by their invasive
or semiquantitative nature. Recent attempts at correlation with jet size from Doppler flow …
