Reliability of left ventricular hemodynamic forces derived from feature-tracking cardiac magnetic resonance.

Background: Hemodynamic forces (HDF) analysis has been proposed as a method to quantify intraventricular pressure gradients, however data on its reliability are still scanty. Thus, the aim of this study is to assess the reliability of HDF parameters derived from cardiac magnetic resonance (CMR).

Methods: CMR studies of 25 athletes were analysed by two independent observers and then re-analysed by the same observer one week apart.
