Is ventricular deformation affine?

Résumé

Recent advances in cardiac diffusion tensor imaging (DTI) have enabled robust imaging of the in vivo heart [1]. This allows to non-invasively assess myofiber and myosheet orientations, which has been a long-standing bottleneck of patient-specific cardiac modeling [2]. Thanks to efficient sequence design, in vivo DTI has even been performed in patients [3] and at multiple cardiac phases [4]. In this study, we analyze dual phase cardiac DTI data of normal humans to investigate the affinity of ventricular deformation. The angulation data is compared to predictions based on myofiber transportation by macroscopic deformation, to quantify the potential relative sliding between myofibers.
