Implication

Supports tensor-based myocardial kinematics analysis in research; leaves open clinical translation beyond animal models.

Key Points

To introduce a new method for quantifying myocardial strain using kinematics in the beating heart.
Utilized a theoretical framework of kinematics to analyze myocardial strain.
Described myocardial displacements using a rotation tensor and a stretch tensor.
Conducted analysis in an anesthetized dog to illustrate the physiological implications.
Demonstrated local twist in the epicardial region quantified by the rotation tensor.
Observed segmental shortening quantified by the stretch tensor.
