Feature tracking strain (FTS) is a new technique to evaluate myocardial deformation from routinely acquired cardiac magnetic resonance (CMR) cine images, however, it has not been validated in single ventricle patients. The purpose of this study is to validate FTS against myocardial tagged harmonic phase (HARP) images, considered the reference standard in non-invasive deformation analysis.
Age in years, media (range)
Single ventricle morphology (LV:RV)
Double outlet right ventricle, n
Hypolastic left heart syndrome, n
Pulmonary atresia, intact ventricular septum, n
Unbalanced AV canal, n
1 unbalanced to left
1 unbalanced to right
Feature tracking analysis has moderate agreement with grid-tagged HARP measurements of circumferential strain in Fontan patients, with a trend towards lower strain values via FTS. Further validation of FTS in a large sample is warranted.
