Intraoperative TEE during mitral valve repair: does it predict early and late postoperative mitral valve dysfunction? Yoshikatsu Saiki, MD, PhD, Hitoshi Kasegawa, MD, Mitsuhiko Kawase, MD, Hiroto Osada, MD, Eiji Ootaki, MD The Annals of Thoracic Surgery Volume 66, Issue 4, Pages 1277-1281 (October 1998) DOI: 10.1016/S0003-4975(98)00756-5

Fig 1 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. The Annals of Thoracic Surgery 1998 66, 1277-1281DOI: (10.1016/S0003-4975(98)00756-5)

Fig 2 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. The Annals of Thoracic Surgery 1998 66, 1277-1281DOI: (10.1016/S0003-4975(98)00756-5)

Fig 3 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. The Annals of Thoracic Surgery 1998 66, 1277-1281DOI: (10.1016/S0003-4975(98)00756-5)

Fig 4 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.
