Interobserver variability for quantitative estimation of maximal regurgitant jet area after mitral valve reconstruction. Regurgitant jet areas measured by one observer in 25 randomly selected cases are compared with findings from a second independent observer. A regression line shows linear and strong (r = 0.96) correlation.

Assessment of residual mitral regurgitation. Comparison of maximal regurgitant jet areas between intraoperative transesophageal echocardiography (TEE) and early postoperative transthoracic echocardiography (TTE). A significant correlation was found between the two measurement despite the different echo windows, timing in evaluation, and possibly different loading conditions.

Assessment of residual mitral regurgitation. Comparison of maximal regurgitant jet areas between intraoperative transesophageal echocardiography (TEE) and late postoperative transthoracic echocardiography (TTE). A good correlation was found between the two measurements.

Individual plots of intraoperative transesophageal echocardiography (TEE), and early and late postoperative transthoracic echocardiography (TTE) maximal regurgitant jet area after mitral valve reconstruction. Of the 40 patients (95%) with no or trivial mitral regurgitation (≤2 cm2), 38 remained mild or had less mitral regurgitation at late postoperative TTE.
