Excessive residual mitral regurgitation after mitral valve reconstruction or coronary artery
bypass graft surgery may necessitate reoperation. We evaluated a new intraoperative …

The ability of color Doppler flow mapping to provide intraoperative information about mitral
regurgitation (MR) severity and to evaluate adequacy of mitral valve repair was assessed by …

Mitral valve repair provides substantial advantages over mitral valve replacement in patients
with severe mitral regurgitation. However, because of the possibility of persistent …

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 …

Objectives. This study was designed to assess the most accurate and reproducible methods
to quantitate mitral regurgitation by color flow trarasthoracic and transesophageal …

Repair procedures that preserve a patient's native valve are associated with a lower
perioperative and late mortality, a lower incidence of thromboembolic events, and better …

To test the role of recently developed biplane transesophageal color Doppler
echocardiography in the assessment of severity of mitral regurgitation, we examined 51 …

BACKGROUND Imaging of the flow convergence region (FCR) proximal to a regurgitant
orifice has been shown to provide a method for quantifying the regurgitant flow rate …

Pulmonary venous flow varies with different cardiac conditions. Flow patterns in response to
mitral regurgitation have not been well studied, but flows may vary enough to differentiate …

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 …
