To observe how much the measurements of function of right ventricle of heart during its relaxation (diastole) phase agree when measured by echocardiography through esophagus (food-pipe) as compared to the standard echocardiography done from over the chest wall

Design outcomes

Primary

MeasureTime frame
Trans-tricuspid early (E) and late (A) diastolic velocities as well as E -wave deceleration time (EDT) will be measured in A4C view by TTE and in Mid-esophageal right ventricular inflow-outflow view, MEB view, DTRVIO view by TEE. Tricuspid annular early (e’) and late (a’) diastolic velocities as well as IVRT will be measured in A4C TTE and in MERVIO view, TGRI view, Deep transgatric right ventricular inflow outflow view by TEETimepoint: single time point at baseline which is immediately after anesthesia induction.—

Secondary

MeasureTime frame
1. To find out the transesophageal echocardiographic views having best agreement with transthoracic echocardiography for measurement of individual Doppler and Tissue Doppler velocities related to right ventricular diastolic function. 2. To find out the feasibility of measuring the right ventricular diastolic Doppler and Tissue Doppler velocities using different views of transesophageal echocardiography.Timepoint: single time point at baseline which is immediately after anesthesia induction.—
