Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Absolute Value of LVEF Percentage Differences From CMR by Blinded Reader | Up to 30 days between day of echocardiograms and CMR imaging | Demonstrate improvement in accuracy in left ventricular ejection fraction (LVEF) assessment using Definity contrast-enhanced over unenhanced echocardiography by comparing LVEF Percentage Differences from CMR measured by 3 independent blinded image readers. |
| Secondary | Secondary Objective 1: Absolute Value of LVEF Percentage Differences From CMR by Blinded Reader for Suboptimal Echocardiograms | Up to 30 days between day of echocardiograms and CMR imaging | Demonstrate improvement in accuracy in left ventricular ejection fraction (LVEF) assessment using DEFINITY® contrast-enhanced over unenhanced echocardiography in subjects with suboptimal echocardiograms by comparing LVEF percentage differences from CMR measured by 3 independent readers. |
| Secondary | Secondary Objective 2: Absolute Value LVEF Percentage Differences From CMR Between Blinded Readers | Up to 30 days between day of echocardiograms and CMR imaging | Demonstrate a reduction in inter-reader variability for the assessment of left ventricular ejection fraction using DEFINITY® contrast-enhanced versus unenhanced echocardiography by comparing LVEF Percentage Differences from CMR between 3 independent blinded readers |
| Secondary | Secondary Objective 3: Absolute Value End-Diastolic and Systolic Volume Differences From CMR Between Blinded Readers | Up to 30 days between day of echocardiograms and CMR imaging | Demonstrate a reduction in inter-reader variability for the assessment of end-diastolic and systolic volumes using DEFINITY® contrast-enhanced versus unenhanced echocardiography by comparing end-diastolic and systolic volume differences from CMR between 3 independent blinded readers. |
| Secondary | Secondary Objective 4: Absolute Value of LVEF Percentage Differences From CMR Between Blinded Readers for Suboptimal Echocardiograms | Up to 30 days between day of echocardiograms and CMR imaging | Demonstrate a reduction in inter-reader variability for the assessment of left ventricular ejection fraction using DEFINITY® contrast-enhanced versus unenhanced echocardiography by comparing LVEF Percentage Differences from CMR between 3 independent blinded readers in subjects with suboptimal echocardiograms. |
| Secondary | Secondary Objective 5: Absolute Value End-Diastolic and Systolic Volume Differences From CMR Between Blinded Readers for Suboptimal Echocardiograms | Up to 30 days between day of echocardiograms and CMR imaging | Demonstrate a reduction in inter-reader variability for the assessment of end-diastolic/systolic volumes using DEFINITY® contrast-enhanced versus unenhanced echocardiography by comparing end-diastolic and systolic volume differences from CMR between 3 independent blinded readers in subjects with suboptimal echocardiograms. |
