Design outcomes

Primary

Measure	Time frame
Both enddiastolic, endsystolic RV and LV volumes, ejection fraction and stroke volumes will be derived. RV and LV stroke volumes will be compared to measure internal validity using a paired samples t-test. Endocardial contours will be manually traced twice for every frame by two observers. These measurements will be compared to measure intra- and inter-observer variability using a paired samples t-test and Bland-Altman-analysis.	—
