1 Tei index to assess perioperative left ventricular systolic function in patients undergoing mitral valve repair  N. Mabrouk-Zerguini, P. Léger, S. Aubert, R. Ray, P. Leprince, B. Riou, P. Coriat, A. Ouattara  British Journal of Anaesthesia  Volume 101, Issue 4, Pages (October 2008) DOI: /bja/aen212 Copyright © 2008 British Journal of Anaesthesia Terms and Conditions

2 Fig 1 Measurement of Tei index. (a) The interval (a) represents the interval between the cessation and onset of mitral inflow (mid-oesophageal four-chamber view). This time corresponds to the sum of isovolumetric contraction, ejection time, and isovolumetric relaxation. (b) Ejection time (b) is measured from the pulsed-wave Doppler recordings of the left ventricular outflow signal (deep transgastric view). The Tei index is defined as the sum of the times of isovolumetric contraction and relaxation times (a–b) divided by the ejection time (b).

5 Fig 4 (a) Correlation existing between observed (FACo) and predicted (FACp) fractional area changes (FAC) using the Tei index in 23 patients included in the study. FACp was calculated using the following formula: FACp=61−Tei index×0.41 (R=−0.64, P<0.001). (b) Bias and variation of the measured FAC after mitral valve repair and the predicted FAC by using the Tei index. The dotted lines represent ±2 standard deviations (precisions of the bias, according to the Bland-Altman method).
