Modified Measurement of Tricuspid Annular Plane Systolic Excursion for Assessing Right Ventricular Function During Cardiac Surgery.

Precise and prompt identification of right ventricular (RV) dysfunction is critical in cardiac surgery. Tricuspid annular plane systolic excursion (TAPSE) has been widely used as a simple, rapid, and repeatable index for assessing RV function. However, the current measurement of TAPSE is based mainly on M-mode ultrasound and is used predominantly in transthoracic echocardiography (TTE). Owing to differences in imaging views and the angle dependence of M-mode ultrasound, directly applying TAPSE measurement from TTE to transesophageal echocardiography (TEE) is not advisable. Therefore, exploring a modified TAPSE measurement method suitable for TEE is of great value for obtaining more accurate TAPSE values and informing subsequent clinical decision making. This review summarizes and discusses in detail the research progress on modified TAPSE in TEE as reported in the literature. By systematically reviewing relevant studies, it aims to provide new methods and insights for cardiac subspecialist anesthesiologists. Modified measurement methods will enable them to more accurately use TAPSE to assess RV function during perioperative TEE. This not only will help optimize clinical decision making, but also will provide an important basis for predicting patients' clinical outcomes.
