EF and CO were determined by TTE AutoEF and TOE, using Doppler velocity time integral (VTI) in the LV outflow tract and the modified Simpson's method. This JSON schema, a list of sentences, is requested. Pearson's correlation coefficients, r, were calculated while also performing Bland-Altman analyses. The primary outcomes of interest were the variations in EF and CO measurements. The secondary endpoints evaluated were variations in left ventri
