- Primary Outcome Measures
Name Time Method Trans-tricuspid early (E) and late (A) diastolic velocities as well as E -wave deceleration <br/ ><br>time (EDT) will be measured in A4C view by TTE and in Mid-esophageal right ventricular inflow-outflow view, <br/ ><br>MEB view, DTRVIO <br/ ><br>view by TEE. <br/ ><br>Tricuspid annular early (eâ??) and late (aâ??) diastolic velocities as well as IVRT will be measured in A4C TTE and in MERVIO view, <br/ ><br>TGRI view, Deep transgatric right ventricular <br/ ><br>inflow outflow view by TEETimepoint: single time point at baseline which is immediately after anesthesia induction.
- Secondary Outcome Measures
Name Time Method 1. To find out the transesophageal echocardiographic views having best <br/ ><br>agreement with transthoracic echocardiography for measurement of individual Doppler and <br/ ><br>Tissue Doppler velocities related to right ventricular diastolic function. <br/ ><br>2. To find out the feasibility of measuring the right ventricular diastolic Doppler <br/ ><br>and Tissue Doppler velocities using different views of transesophageal echocardiography.Timepoint: single time point at baseline which is immediately after anesthesia induction.
