Összefoglaló szövege

The measurement of left ventricular (LV) volumetric and strain parameters in patients with noncompaction cardiomyopathy (NCMP) with 2D and 3D speckle tracking echocardiographic (2D-STE, 3D-STE) is more challenging than the same with cardiac MRI (CMR).
The agreement of these imaging modalities has been already studied in different cohorts but not in patients with NCMP.
Our aim was to assess the correlation and agreement between CMR, 2D-STE, and 3D-STE by comparing the volumetric and strain values of NCMP and healthy control participants.
We studied 21 NCMP patients who had no co-morbidities and 21 control participants (NCMP: age: 37±15 years EF: 67.5±3.9%; Control: age: 17±3years, EF: 58.8±4.4%) with Philips Achieva 1.5 T scanner, and GE Vivid E95 echocardiography equipment. Medis Suite, TOMTEC 4D LV-Analysis 3, and TOMTEC Cardiac Performance Analysis software were used for post-processing. Data were analyzed with Pearson’s correlation and Bland-Altman plots with percentage error (PE). P <0.05 was considered as significant. Volumetric data were indexed to body surface area.
Volumetric measurements correlated well between the studied modalities in both group (NCMP and control groups: end-diastolic volume: r between 0.7 and 0.9, end-systolic volume: r between 0.7 and 0.8, stroke volume: r=0. 7) while the strain parameters showed poor correlation.
We found better agreement between CMR and 2D and 3D echocardiography in the healthy group than in patients (p = 0.01). However, only the healthy subjects’ global strain values showed good agreement between the modalities (GLS MR-2D: p<0.014 PE=23.4 %; MR-3D: p<0.01 PE=24.7 %; GCS MR-2D: p<0.01 PE=20,7 %; MR-3D: p<0.01 PE=23.7 %).
Our pilot study suggests that LV hypertrabeculation may cause difficulties in measuring STE strain parameters. Further studies are needed to find the optimal follow-up modality for this patient population.
