简要总结
This is a Phase 3, prospective, open-label, multicenter study to evaluate Left Ventricular Ejection Fraction (LVEF) measurement accuracy and reproducibility of DEFINITY® contrast-enhanced and unenhanced echocardiography as compared with non-contrast cardiac magnetic resonance imaging (CMR) used as the truth standard.

排除标准
- •Female subjects who are pregnant or lactating. All women of child bearing potential [WOCBP] must have a negative urine pregnancy test at screening regardless of contraceptive use history.
- •Women of child-bearing potential are excluded unless they:

- •have been using an adequate and medically approved method of contraception to avoid pregnancy for at least 1 month prior to DEFINITY® dose administration and be willing to continue using the same method for the duration of the study.
- •Current illness or pathology that would prevent undergoing investigational product administration due to a significant safety risk to the patient.
- •Uncontrolled arterial hypertension (defined as systolic blood pressure ≥ 200 mmHg or diastolic blood pressure ≥ 110 mmHg) or arterial hypotension (defined as systolic blood pressure ≤ 90 mmHg).
- •Unstable cardiovascular status defined as:
- •myocardial infarction or unstable angina pectoris within 6 months prior to enrollment/DEFINITY® dose administration day
- •transient ischemic attack or stroke within 3 months prior to DEFINITY® dose administration
- •symptomatic valvular heart disease or moderate to severe stenotic valvular heart disease
- •clinically significant congenital heart defects
- •current uncontrolled cardiac arrhythmias causing symptoms or hemodynamic compromise
- •acute pulmonary embolus or pulmonary infarction
- •acute myocarditis or pericarditis
- •acute aortic dissection
- •atrial fibrillation
- •any major surgery within 4 weeks prior to screening
- •known contraindications to undergoing CMR or claustrophobia
- •participation in any investigational drug, device, or placebo study within 30 days prior to screening
- •known hypersensitivity to perflutren, or any of the excipients in DEFINITY®
- •prisoners or those who are subject to compulsory detention or involuntary incarceration for treatment of either a psychiatric or physical illness (e.g., infectious disease) -
