Table 3. Echocardiographic assessment at 28th-week post surgery. BW, body weight; HR, heart rate; LVDD, left ventricle diastolic diameter; DPWT, diastolic posterior wall thickness; LA/Ao, left atrium to aorta ratio; EF, ejection fraction; MFS, mesocardial shortening fraction; PWSV, posterior wall shortening velocity; EDT, E-wave deceleration time; IVRT isovolumetric relaxation time; S': tissue Doppler imaging (TDI) of systolic; E/A, E wave to A wave ratio; e': TDI of early diastolic velocity of mitral annulus; a': TDI of end-diastolic velocity of mitral annulus; E/e': E wave to e' ratio. Data expressed as mean ± SD. p<0.05. * vs. Sham; ^& vs. ShamT; ^# vs. AS. (n = 15-22 each group)
