In the published article, there was an error in Results, Left ventricular strain and M-mode assessment of left ventricular functional parameters, Paragraph 1. The results of global longitudinal strain (GLS) in SMA children and healthy controls were incorrectly stated. The results were previously stated as “The GLS was significantly decreased in SMA children (−23.3 ± 1.9%, p < 0.001) compared to healthy controls (−18.7 ± 2.9%)” but should be, “The GLS was significantly decreased in SMA children (−18.7 ± 2.9%, p < 0.001) compared to healthy controls (−23.3 ± 1.9%).” The corrected paragraph appears below:
LV strain, as assessed by 2D-STE, and LV dimensions, LVEF, and LVFS, as measured by M-Teich, in SMA patients and controls were examined. Significant differences between the two groups were also observed in longitudinal strain and TTPLS under different views, such as AP4, AP2, and AP3. The GLS was significantly decreased in SMA children (−18.7 ± 2.9%, p < 0.001) compared to healthy controls (−23.3 ± 1.9%) (Figure 1). The TTPLS was significantly prolonged in SMA children compared to healthy controls (22.9 ± 13.6 ms and 14.2 ± 9.2 ms, respectively; p < 0.001). However, no significant differences were observed in LV dimensions measured by M-Teich between SMA children and controls. Regarding LV function parameters analyzed by M-Teich, a difference in LVEF was found between the two groups, but it was within the normal range of the reference value (LVEF ≥ 50%), while there was no significant difference in LVFS between the two groups (Table 2).
