Comparative StudyTricuspid Annular Plane Systolic Excursion: Comparing Transthoracic to Transesophageal Echocardiography.
Tricuspid annular plane systolic excursion (TAPSE) represents movement of the lateral annulus of the tricuspid valve toward the apex and denotes right ventricular contractility in the long axis. In transesophageal echocardiography with the probe in the mid-esophagus, TAPSE occurs at a significant angle to the M-mode scan line. The authors describe a novel method to assess TAPSE in 2 dimensions (2D) and compare this with an established method. ⋯ Transesophageal 2D-TAPSE appeared to be a reliable and simple method to assess right ventricular function, and demonstrated a close correlation with transthoracic M-TAPSE.
