Circumferential strain recovery after human cardiomyocyte transplantation in minipigs using a novel frequency-based method for myocardial tagging quantification.

However, circumferential strain results obtained with feature tracking method had larger variability, and, despite of the similar trend, regional CS differences between cell-treated and vehicle-control groups in the infarcted zone (anterior and anteroseptal segments combined) did not reach statistical significance at 4-week post-treatment ( Fig. 4 c), while our novel frequency-based approach detected the difference in strain at 4- as well as at 8-weeks post-treatment ( Fig. 4 b). 3.4.
