Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint is the achieved CT density in the left ventricle as well as in the aortic bulbus. The CT density is systematically analyzed in all patients after completion of the recruitment. Therefore, in the CT data the average CT density is determined in a 1 cm² measurement in the left ventricular cavity as well as in the aortic bulbus. | — |
Secondary
| Measure | Time frame |
