Design outcomes

Primary

Measure	Time frame
The primary aim of the study is to assess the agreement between automated (Auto-GLS) and manual expert measurement of left ventricular global longitudinal strain (LV-GLS) on in-traoperatively recorded TEE images.Timepoint: Baseline; Once Before Incision	—

Secondary

Measure	Time frame
As a secondary aim, the agreement between automated (Auto-EF) & manual expert meas-urement of left ventricular ejection fraction (LV-EF) will be evaluated.Timepoint: Baseline; Once before incision	—
