Myocardial volume change during cardiac cycle derived from three orthogonal systolic strains: towards a quality assessment of strains

Abstract : Background The relative modification of the myocardial volume between end-systole and end-diastole ([Formula: see text]) has already been assessed with different methods and falls in a range of 0.9–0.97 (mean value = 0.93). Purpose To estimate [Formula: see text] from the three longitudinal ([Formula: see text], circumferential ([Formula: see text]), and radial ([Formula: see text]) strains of the left ventricle using the formula: [Formula: see text] and to test whether this estimate of [Formula: see text] can be used as a marker of the echocardiography quality. Material and Methods Two hundred manuscripts, including a total of 34,690 patients or healthy volunteers, were identified in the Medline database containing values of [Formula: see text], [Formula: see text], and [Formula: see text] measured from echocardiography. Results The median value of was 0.93, in accordance with the literature, with no significant difference between patients or healthy volunteers ( P = 0.38). The proportion of studies with [Formula: see text] was 79%. When only considering groups of healthy volunteers, the studies failing this test had higher standard deviations for the three individual strains: 0.038 vs. 0.029 ( P = 0.02) for [Formula: see text]; 0.060 vs. 0.034 ( P < 10 –6 ) for [Formula: see text], and 0.243 vs. 0.101 ( P < 10 –14 ) for [Formula: see text]. Conclusion The median ratio of the left ventricular myocardial volumes between end-systole and end-diastole in the investigated studies was [Formula: see text]. The formula [Formula: see text] could be used to detect studies with inaccurate strain measurements.
