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 …

Qualitative grading of mitral regurgitation severity has significant pitfalls secondary to
hemodynamic variables, sonographic technique, blood pool entrainment, and the Coanda …

The proximal flow convergence method of multiplying color Doppler aliasing velocity by flow
convergence surface area has yielded a new means of quantifying flow rate by …

Improvements in outcomes for heart valve surgery, in particular mitral valve repair, have
dictated a need for better assessment of valvar regurgitation. Whereas in the past surgery …

A three-dimensional understanding of the blood flow dynamics and cardiac structures was
afforded in all 53 cases studied with the biplane color transesophageal echocardiography …

To determine the ability of Doppler color flow mapping to accurately and reproducibly
assess the flow volume and kinetic energy of in vitro fluid Jets, a Doppler color flow mapping …

Contrast techniques have been used to improve detection of peak velocities by Doppler
spectral analysis. To define the effect of contrast enhancement on the tricuspid regurgitation …

BACKGROUND: Real-time 3-dimensional color Doppler echocardiographic (RT3DE)
imaging has recently been demonstrated to provide accurate direct measurement of vena …

Objective: This study was designed to develop and test a 3-dimensional method for direct
measurement of flow convergence (FC) region surface area and for quantitating regurgitant …

Background Assessment of mitral regurgitation (MR) severity by echocardiography is
important for clinical decision making, but MR severity can be challenging to quantitate …
