Corrigendum: A head-to-head comparison of myocardial strain by fast-strain encoding and feature tracking imaging in acute myocardial infarction

In the published article, measurements in Table 2 were displaced. A formatting error resulted in strain percentage with confidence interval for the first and third lines were displayed upwards. The published Table 2 is printed below, followed by the corrected Table 2 and its caption.

Table 2.

Global circumferential and longitudinal strain.

Myocardial strain direction Mean % (SD) 95% CI for mean
GCS −13.6 (3.7) −14.9 to −12.2
Fast-SENC
FT −13.6 (3.7) −15.0 to −12.2
GLS −14.8 (2.9) −15.9 to −13.7
Fast-SENC
FT −13.0 (2.8) −14.0 to −11.9
2DEcho −13.3 (3.7) −14.7 to −11.9

Global circumferential strain (GCS) and global longitudinal strain (GLS) derived from fast-SENC, FT and 2DEcho. Means and standard deviation (SD) in parenthesis with 95% confidence intervals are presented.

Faulty Table 2:

In the published article, three figures that displayed SD in the first paragraph under “Results” were printed as hyperlinks to the list of references.

The authors wish that a correction is made to “Results, scar and ejection fraction” in terms of removing the hyperlinks displayed below. These sentences previously stated:

Scar and ejection fraction

The subjects were enrolled and treated with the pPCI after identification of the culprit artery in each case. The cohort displayed a median door-to-balloon time of 67 min. The average scar size was 15 (9) % of LVM with a median Troponin-T of 1,640 ng/l, equivalent to 164 × upper level of normal. LGE revealed scars in 240 out of 510 segments (47%) with 122 segments having scar transmurality <25%, 78 segments between 25 and 49%, and only 40 segments had a transmurality ≥50%. In 13 patients the LVEFCMR was little affected, LVEFCMR ≥ 50%. Patients with maintained LVEFCMR had smaller scar size 10 (5)% than those with depressed LVEFCMR <50% whose scar size was 19 (10)%, (p < 0.01). Patient demographics and CMR imaging characteristics are presented in Table 1.”

The corrected sentences appears below:

“The subjects were enrolled and treated with pPCI after identification of the culprit artery in each case. The cohort displayed a median door-to-balloon time of 67 min.

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
