Comparison of LVSV and reference SV in 15 patients with no significant mitral regurgitation. Regression (top panels) and Bland-Altman (bottom panels) plots comparing LVSV and the reference stroke volume (RVSV) in 15 patients with no significant mitral regurgitation. With the uncorrected method, the LVSV was higher than the reference stroke volume (left hand panels), while with the corrected method, no significant difference was measured (right hand panels). a Correlation between uncorrected and reference SV in patients with no mitral regurgitation b Correlation between corrected and reference SV in patients with no mitral regurgitation (MR) c Agreement between uncorrected and reference SV in patients with no MR d Agreement between corrected and reference SV in patients with no MR
