Table 2: Comparison between PW DTI and TVI methods for systolic, early and late diastolic velocities measured at MA, TA and AA annuli assigned by two-way within factor ANOVA’s. (Velocities in mm/s). MA: Mitral Annulus; TA:Tricuspid Annulus; AA:Aortic Annulus; PW DTI: Pulsed Wave Tissue Doppler Imaging; TVI:Colour Coded Tissue Doppler Imaging; CI: Confidence Interval (n=24).
