Comparative Study Observational StudyThe feasibility of tricuspid annular plane systolic excursion performed by transesophageal echocardiography throughout heart surgery and its interchangeability with transthoracic echocardiography.
Tricuspid annular plane systolic excursion (TAPSE) is a robust measure of RV function, but the performance of transesophageal echocardiography (TEE) measured TAPSE during surgery is not well established. We aim to evaluate feasibility of various TEE views before, during and after surgery. Furthermore, we compare performance of individual TEE measurements depending on view and method (AMM- and M-mode as well as 2D) as well as TAPSE measured using TEE with transthoracic echocardiography (TTE) TAPSE. ⋯ TDI demonstrated a high reliability throughout surgery. RV function can be evaluated by TAPSE and TDI using TEE during surgery. TEE values from the transgastric view demonstrated high performance throughout surgery and a good agreement with TTE TAPSE measurements.
