Cardiac Mechanics Analysis
Retrospective LA and LV measurements were performed offline by a single
operator who was unaware to clinical and echocardiographic data, using
special software (eSie VVI, Siemens Medical System, Mountain View). An
average cardiac cycle (of 2-3 cycles) was created for each
representative view and the onset of R wave was used as the reference
point for both LA and LV strain and volume curves.
