Figure 1




Figure 1 : 

Intraobserver (A), interobserver (B) and test–retest (C) variability for left ventricular end-diastolic volume (EDV) and end-systolic volume (ESV) obtained with three-dimensional HeartModel software, using linear regressions.

Figure 2 : 

Linear regression (left) and Bland–Altman (right) diagrams of comparison between three-dimensional transthoracic echocardiography using HeartModel (HM) software and cardiac magnetic resonance (CMR) for the assessment of: (A) left ventricular end-diastolic volume (EDV); (B) left ventricular end-systolic volume (ESV); and (C) left ventricular ejection fraction (EF). SD: standard deviation.

Figure 3 : 

Comparison of regurgitant volume (RV) obtained by the proximal isovelocity surface area (PISA) method, by cardiac magnetic resonance (CMR) and by a volumetric method using new three-dimensional HeartModel (HM) software.


Figure 4




Figure 4 : 

Linear regression (left) and Bland–Altman (right) diagrams of comparison of regurgitant volume (RV) as determined by (A) the proximal isovelocity surface area (PISA) method and (B) a volumetric method using new three-dimensional HeartModel (HM) software, taking cardiac magnetic resonance (CMR) RV as reference. SD: standard deviation.

Figure 5 : 

Individual data of regurgitant volume (RV) as determined by (A) the proximal isovelocity surface area (PISA) method and (B) a volumetric method using new three-dimensional HeartModel (HM) software, according to the mitral regurgitation severity determined by cardiac magnetic resonance.
