Atrioventricular plane displacement versus mitral and tricuspid annular plane systoli excursion: A comparison between cardiac magnetic resonance and M-mode echocardiography

Abstract

Introduction: Both echocardiography and CMR imaging are used to quantify longitudinal function. Inter-method variability for mitral (MAPSE) and tricuspid (TAPSE) annular plane systolic excursion, and variability between directly measured MAPSE and TAPSE and as based on atrioventricular plane displacement (AVPD) analysis by CMR, are, however, not known. This study, therefore, assessed inter-method variability and variability between annular plane systolic excursion and AVPD-based values in a healthy adult population. Methods: Echocardiography and CMR were performed in 111 adults (35 [32–38] years). Method comparisons were assessed with Deming regression, Bland–Altman analysis and coefficient of variation. Observer reproducibility was assessed by the concordance correlation coefficient. Results: Echocardiography and semi-automatic CMR agreed on MAPSE (17 ± 2 mm vs. 17 ± 2 mm, p = 0.1) and TAPSE (25 ± 3 mm vs. 25 ± 3 mm, p = 0.5), correlated highly between methods (fitted-slope 1.22 [95% CI 1.07–1.38] and 1.12 [95% CI 0.95–1.29]) and showed low bias (0.42 [95% CI − 2.05 to 2.88] and − 0.18 [95% CI − 4.78 to 4.43]). Intra-/ inter-observer reproducibility was high for both methods for both. MAPSE (echocardiography 0.96/0.86; CMR 0.87/0.85) and TAPSE (echocardiography 0.96/0.95; CMR 0.97/0.96). MAPSE (16 ± 2 mm vs. 17 ± 2 mm; p < 0.001) and TAPSE (24 ± 3 vs. 25 ± 3 mm; p < 0.001) based on AVPD were similar but statistically different compared with semi-automatic CMR. Conclusions: Echocardiography and semi-automatic CMR have low variability and provide similar values for MAPSE and TAPSE and are thus interchangeable for follow- up studies. Lateral values based on tracked data from AVPD analysis are not clinically significantly different and could be used as a representation of annular displacement. ; Erasmus Mundus Region of Skane Skane University Hospital Lund Medical Faculty at Lund University Knut & Alice Wallenberg Foundation Instituto de Salud Carlos III European Commission PI15/00130 PI14/00226 PI17/00675 INT16/00168 por el ISCIII-Subdireccion General de Evaluacion y el Fondo Europeo de Desarrollo Regional (FEDER) `Otra manera de hacer Europa' (Spain) Erasmus + Programme of the European Union 2013-0040 La Caixa Foundation LCF/PR/GN14/10270005 AGAUR 2014 SGR grant 928 Swedish Heart-Lung Foundation ; Versión publicada - versión final del editor
