Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
<p>The time needed to manually trace 1 cardiac cycle will be timed using a<br /><br>stopwatch.</p><br>
