“…18 The Vcf was lower in the deceased group than in the survivors, in whom it was in the normal range. 19 Estimation of wall stress-fiber shortening relationship shows that this index is lower in patients with depressed contractility rather than in those with high after-loads. 20 Tei et al compared normal adults and patients with IDCM and found normal MPI as 0.39±0.05, 0.59±0.10 in functional class II, and 1.06±0.24 in functional class III/IV patients.…”

Background: Myocardial performance index (MPI) was reported as a parameter of ventricular systolic and diastolic function, as well as a useful tool to predict the outcome in patients with ventricular dysfunction. Hypothesis: To compare MPI with classical echocardiographic parameters as an independent marker of death in children with idiopathic dilated cardiomyopathy (IDCM). Methods: Fifty-five children (13 deaths) underwent 104 echocardiograms from January 1996 to May 2005. Right ventricle (RV) MPI and left ventricle (LV) MPI, and 9 classical echocardiographic parameters (left atrium [LA]/body surface area [BSA], distance between mitral E point and ventricular septum, LV mass/body surface area, RV shortening fraction, LV end-systolic and end-diastolic dimensions/body surface area, LV ejection fraction, fiber circumferential shortening velocity, and mitral deceleration time) were compared. Statistical analysis was performed by chi-square, Pearson's correlation and Student t-test, Kaplan-Meier method, Cox's method, and receiver operating curve (ROC). Statistical significance was considered with α<0.05 and p = 0.80. Results: Univariate analysis showed that all studied parameters were markers of death. There was a high correlation between RVMPI and LVMPI (r = 0.847-p = 0.0001); therefore, to avoid bias, RVMPI was discharged from multivariate analysis. In the deceased group, moderate/severe mitral regurgitation was frequent (76.9%; confidence interval [CI] 95% = 46.2%-94.9%) and it was considered in multivariate analysis. In Cox's multivariate analysis, LVMPI was the only independent marker of death (p = 0.0213). The ideal cut-off was 0.63 with 92.3% sensitivity, 66.7% specificity, and fitted ROC area = 0.918. Conclusions: In children with IDCM, LVMPI is an independent marker of death.

“…The reader is referred to other resources for a more detailed discussion of the theoretic principles for these measurements and for the technical aspects of their performance. [43][44][45][46][47][48][49][50] The recommended measurements are grouped into measurements of cardiovascular structures, ventricular size and function measurements, hemodynamic measurements, and miscellaneous measurements.…”

“…Normative data for many cardiovascular structures exist, [44][45][46][47][48][49][50] and are generally adjusted to a calculation of body surface area using the height and weight of the patient. Valve and vascular diameters relate linearly to the square root of body surface area, whereas valve and vascular areas relate to body surface area.…”

“…In general, body weight was used to express normal values in newborns, whereas body surface area was chosen for infants and older children. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] In this study, we aimed to measure the right ventricle, left ventricle, interventricular septum, aorta, and left atrium diameters using M-mode echocardiography to determine the normal values of healthy newborns. According to these suggested normative data, it can be determined whether newborns have normal or abnormal echocardiographic measurements.…”
