Correlations between invasive and noninvasive data in all animals.

Values are mean ± SD.
AFF = atrial filling fraction; LV = left ventricle; AcT TTE = aceleration time of right ventricular outflow (transthoracic echocardiography); AcT TEE = aceleration time of right ventricular outflow (transesophageal echocardiography); TT = time from the beginning to the end of right ventricular outflow; CI = cardiac index; LVMass = left ventricular mass; MPI = myocardial performance index; EF = ejection fraction; E/E’ =  ratio of peak velocity of E wave of mitral inflow and peak velocity of early diastolic velocity obtained by tissue Doppler imaging; EDP = end-diastolic pressure.
