The aim of the present study was to evaluate different contributions of noncompacted and compacted LV segments to the global LV dysfunction by three-dimensional (3D) speckle tracking echocardiography (3DSTE)-derived strain parameters in NCCM. Patients and Methods: The present study comprised 9 patients with typical features of NCCM. Due to the limited image quality, one patient was excluded from the evaluations. Finally, 128 segments of 8 NCCM patients were assessed. Their results were compared to 176 segments of 11 healthy volunteers. Complete two-dimensional Doppler echocardiography extended with 3DSTE has been performed in all cases. Results: Fifty-five of 128 LV segments (43%) proved to be noncompacted in NCCM patients. All strain parameters of segments of NCCM patients were significantly lower as compared to segments of controls. Only radial strain (6.99 ± 7.36% vs. 12.58 ± 12.78% vs. 25.24 ± 11.76%, P < 0.001 and P < 0.05, respectively) and 3D strain (7.79 ± 7.59% vs. 14.67 ± 14.04% vs. 27.78 ± 12.57%, P < 0.001 and P < 0.05, respectively) showed further reduction in noncompacted segments as compared to compacted segments. Conclusions: Left ventricular strain reduction is not confined to the nocompacted segments in NCCM. Radial and 3D strain parameters show further reduction in noncompacted segments compared to compacted segments. © 2013, Wiley Periodicals, Inc.
