简要总结
Quantitative assessment of right ventricle (RV) function is clinically valuable because RV function has prognostic significance in various cardiac and lung pathologies.Right Ventricle (RV) has a very important role in determining intraoperative and post operative outcomes of cardiopulmonary surgeries. Assessment of RV diastolic function can
help in anticipating of post-operative complications after cardiopulmonary surgeries In a study, values of right ventricular systolic function by TEE have been shown to have only fair agreement to TTE measurements obtained in close temporal proximity under similar hemodynamic conditions Therefore, we intend to perform a study evaluating the agreement between transthoracic and transoesophageal echocardiography in measurement of right ventricular diastolic Doppler and tissue Doppler velocities in adult patients undergoing cardiac surgery.
Based on the finding of our study, we can decide whether the right ventricular diastolic Doppler and tissue Doppler velocities measured by TEE can be used interchangeably with those measured by standard TTE
