- 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.
|Study Type :||Observational|
|Actual Enrollment :||112 participants|
|Official Title:||Validation of Speckle-tracking Echocardiography Measurements of Tricuspid Annular Plane Systolic Excursion During Transesophageal Echocardiography|
|Study Start Date :||May 2014|
|Actual Primary Completion Date :||February 2015|
|Actual Study Completion Date :||November 2015|
All patients in the cohort will be scheduled to undergo a planned surgical procedure in which the subject will undergo general anesthesia and the procedure and/or the patient will require transesophageal echocardiographic monitoring for the procedure.
Other: Concurrent TTE and TEE
All subjects will undergo both transthoracic echocardiography and transesophageal echocardiography to compare the results of measurements obtained from both imaging locations.
