“…5.a we plot the observed R 2 values of the real data for the first two PCA modes along with the synthetic R 2 curves for the same PCA modes. We can see that the noise factor is around 10%, which coincides with the results obtained by D'hooge et al in [10]. We have also compared the regression results when different types of measurements are used as predictors.…”

Many cardiac diseases are associated with changes in ventricular shape. However, in daily practice, the heart is mostly assessed by 2D echocardiography only. While 3D techniques are available, they are rarely used. In this paper we analyze to which extent it is possible to obtain the 3D shape of a left ventricle (LV) using measurements from 2D echocardiography. First, we investigate this using synthetic datasets, and afterwards, we illustrate it in clinical 2D echocardiography measurements with corresponding 3D meshes obtained using 3D echocardiography. We demonstrate that standard measurements taken in 2D allow quantifying only the ellipsoidal shape of the ventricle, and that capturing other shape features require either additional geometrical measurements or clinical information related to shape remodelling. We show that noise in the measurements is the primary cause for poor association between the measurements and the LV shape features and that an estimated 10% level of noise on the 2D measurements limits the recoverability of shape. Finally we show that clinical variables relating to the clinical history can substitute the lack of geometric measurements, thus providing alternatives for shape assessment in daily practice.

Background The aim of present study was to assess left ventricular (LV) myocardial deformation and changes over time in patients with acute myocarditis (AM) with preserved ejection fraction detected by late gadolinium enhancement (LGE) magnetic resonance imaging. Methods Thirty‐five male patients with AM diagnoses and preserved systolic function based on cardiac magnetic resonance imaging (MRI) were prospectively enrolled. On admission, echocardiography with measurements of global and segmental longitudinal (LS) strains was performed both at the endocardial (ENDO) and epicardial (EPI) levels. Findings were compared to 25 control subjects. Twenty‐six patients were also monitored over a 22‐month follow‐up (FU group). Results On admission, global ENDO‐LS was poorer in magnitude in AM (−19.2 ± 3.1) than in controls (−24.0 ± 1.05) (P < 0.0001), whereas EPI‐LS was not different (−20.6 ± 3.4 vs −19.7 ± 6 P = NS). A functional increase in magnitude in both ENDO‐LS (−20.8 ± 5.4, P = NS) and EPI‐LS (−22.6 ± 4.6, P = 0.02) was found in FU vs AM patients. Conclusions The present study demonstrates a steady ENDO‐LS impairment in infarct‐like AM during a 2‐year follow‐up period, despite a preserved LV ejection fraction.

“…This semi-recent technique has been widely demonstrated as a sensitive marker of LV dysfunction and patient outcomes. However recent reports have pointed out its high inter-vendor variability 25 encouraging the learned society of echocardiography to focus on homogenizing the type of stored data used to quantify left ventricular strain. We believe that a similar reflection should be carried out on measurements based on flow color Doppler data.…”

Assessment of intraventricular pressure gradients (iVpG) using color Doppler M-mode echocardiography has gained increasing interest in the evaluation of cardiac function. However, standardized analysis tools for IVPG quantification are missing. We aimed to evaluate the feasibility, the test-retest observer reproducibility, and the inter-system variability of a semi-automated IVPG quantification algorithm. The study included forty healthy volunteers (50% were men). All volunteers were examined using two ultrasound systems, the Philips Epiq 7 and the General Electric Vivid 6. Left ventricular diastolic (DiVpG) and systolic (SiVpG) intraventricular pressure gradients were measured from the spatiotemporal distribution of intraventricular propagation flow velocities using color Doppler M-mode in standard apical views. there was good feasibility for both systolic and diastolic iVpG measurements (82.5% and 85%, respectively). Intra and inter-observer test-retest variability measured with the intraclass correlation coefficient were 0.98 and 0.93 for DIVPG respectively, and 0.95 and 0.89 for SiVpG respectively. the inter-system concordance was weak to moderate with Lin's concordance correlation coefficient of 0.59 for DIVPG and 0.25 for SIVPG. In conclusion, it is feasible and reproducible to assess systolic and diastolic IVPG using color Doppler M-mode in healthy volunteers. However, the inter-system variability in IVPG analysis needs to be taken into account, especially when using displayed data.
