Background: Hemodynamic and functional evaluation with Doppler and tissue Doppler study as a part of comprehensiveechocardiography is essential but normal reference values have never been reported from Korean normal population especially accordingto age and sex. Methods: Using Normal echOcaRdiographic Measurements in a KoreAn popuLation study subjects, we obtained normal referencevalues for Doppler and tissue Doppler echocardiography including tricuspid annular velocities according to current guidelinesand compared values according to gender and age groups. Results: Mitral early diastolic (E) and late diastolic (A) velocity as well as E/A ratio were significantly higher in women comparedto those in men. Conversely, mitral peak systolic and late diastolic annular velocity in both septal and lateral mitral annuluswere significantly lower in women compared to those in men. However, there were no significant differences in both septal andlateral mitral early diastolic annular (e’) velocity between men and women. In both men and women, mitral E velocity and its decelerationtime as well as both E/A and E/e’ ratio considerably increased with age. There were no significant differences in tricuspidinflow velocities and tricuspid lateral annular velocities between men and women except e’ velocity, which was significantlyhigher in women compared to that in men. However, changes in both tricuspid inflow and lateral annular velocities according toage were similar to those in mitral velocities. Conclusion: Since there were significant differences in Doppler and tissue Doppler echocardiographic variables between menand women and changes according to age were even more considerable in both gender groups, normal Doppler echocardiographicvalues should be differentially applied based on age and sex.
