OBJECTIVE: To assess the agreement between 2-dimensional tricuspid annular plane systolic excursion (2D-TAPSE), 2D-TAPSE-apex, and 2D speckle tracking echocardiography (STE-TAPSE) in a cross-section of routine cardiac surgery patients.
DESIGN: Retrospective, observational study.
SETTING: Tertiary, academic referral hospital.
PARTICIPANTS: Patients undergoing elective cardiac surgery with intraoperative transesophageal echocardiography (TEE) imaging.
INTERVENTIONS: TEE imaging was reviewed and evaluated for the following three different measurements of transthoracic echocardiography-TAPSE surrogates: 2D-TAPSE, 2D-TAPSE-apex, and STE-TAPSE. Statistical analyses, including 2-sample t tests, linear regression, and agreement using the Bland-Altman methods, were performed.
MEASUREMENTS AND MAIN RESULTS: Modest correlation was demonstrated between STE-TAPSE and 2D-TAPSE (R
CONCLUSIONS: Correlation and minimal bias were found between the several proposed TEE surrogates of transthoracic echocardiography-TAPSE; however, there was poor agreement. Therefore, these surrogates are not interchangeable, and each method needs to be separately validated for clinical use to relevant perioperative outcomes
