Use of speckle-tracking echocardiography to validate tricuspid annular plane systolic excursion measurements with transesophageal echocardiography.~This study intends to validate the use of speckle-tracking echocardiography to measure the distance the tricuspid annulus moves during the systolic phase. The guideline articles regarding right ventricular function suggest m-mode measurements from the transthoracic approach and the same measurements may underestimate the actual distance on transesophageal echocardiography. This speckle-tracking technology will allow this distance to be measured despite its often non-parallel motion to the ultrasound beam, which otherwise limits the reliability of the valve recorded.~All subjects undergoing a planned surgical procedure in which the use of transesophageal echocardiography would be used regardless for their management.~No interventions, only evaluation of the measurements obtained with transthoracic echocardiography compared to transesophageal echocardiography.~No follow-up, study will be completed at the time of image acquisition.
The study is designed to validate the use of speckle-tracking echocardiography to measure tricuspid annular plane systolic excursion as a measurement of right ventricular function during transesophageal echocardiography.
