Agreement of tricuspid annular systolic excursion measurement between transthoracic and transesophageal echocardiography in the perioperative setting

Abstract

Our study showed that the right ventricular function can be accurately and precisely estimated using TAPSE measurement by TEE in the midesophageal four chamber and deep transgastric right ventricle view at 0° using anatomical M-mode.

Tricuspid annular plane systolic excursion is significantly reduced during uncomplicated coronary artery bypass surgery: A prospective observational study

“…In contrast, the M-mode in the transgastric view although showing high feasibility and reproducibility carries a systematic underestimation of TAPSE compared with TTE. 13,30 Still, the sequential changes in M-mode TAPSE seen in the current study was in agreement with the anatomic M-mode in the transgastric view, which as described has shown high feasibility, high reproducibility, as well as high interchangeability with TTE TAPSE, thus strengthening the findings.…”

“…13 In that study we found that anatomic M-mode in the transgastric view showed the best performance compared with TTE throughout surgery. Flo Forner and colleagues 30 have also shown good agreement between TTE and TEE anatomic M-mode TAPSE, but only in the preoperative setting-not throughout surgery. In contrast, the M-mode in the transgastric view although showing high feasibility and reproducibility carries a systematic underestimation of TAPSE compared with TTE.…”

“…6 Validation and comparison of TEE TAPSE with TTE TAPSE has only been carried out to a limited extent. 30,31 A strength in the current study was that we applied TEE views and assessment of TAPSE on the basis of observations from a previous investigation. 13 In that study we found that anatomic M-mode in the transgastric view showed the best performance compared with TTE throughout surgery.…”

Role of Echocardiography for the Perioperative Assessment of the Right Ventricle

“…Alternative views with superior alignment exist for visualization of the RV [22]. Particularly, the modified deep transgastric view focusing the right ventricle and the transgastric RV inflow view has been evaluated in the literature, however, showing underestimation of TAPSE by TEE using these alternative views in comparison to TAPSE by TTE using an apical four-chamber view [26,27]. Therefore, alternative and less angle-dependent techniques seem more promising.…”

“…Therefore, alternative and less angle-dependent techniques seem more promising. Measurement of TAPSE by anatomic M-mode which evaluates two-dimensional pixel samples along a freely positioned cursor line presented increased precision [26,28]. A further approach is to measure TAPSE with speckle-tracking echocardiography, which is mainly angle-independent [28,29].…”
