About

Transversal retrospective and unicentric study. The investigators sought to determine the normal values for two-dimensional myocardial left atrial strain for the cardiology ultrasound system available in their centre (Philips EPIQ ultrasound machine and 10.8.5 QLAB cardiac analysis software). Studies performed in their department which meet the criteria for an adequate strain analysis will be retrospectively reviewed.
