Why Use DEFINITY®? PROVEN EFFICACY PROFILE


DEFINITY® improves visualization in the vast majority of studies—with the greatest improvement in lateral and anterior walls.1,2*

Using contrast may help answer the clinical question in suboptimal echoes2,3

Up to 20% of resting studies will result in suboptimal echocardiograms3,4,5

The use of contrast may reduce the need for subsequent testing2,6

A suboptimal image is one in which at least 2 out of 6 myocardial segments of the left ventricle cannot be visualized in the apical views, as defined by the American Society of Echocardiography (ASE) 3,4

*Pooled data on file from 126 patients in two open-label multicenter trials with similar study design and patient populations. Results from institutional reads refer to percentage of patients with improvement in segmental endocardial border delineation after administration of one or more 10µL/Kg boluses of DEFINITY®. Tests of significance were conducted using 2-sided McNemar's test at the 5% level of significance.

INDICATIONS

Activated DEFINITY® (Perflutren Lipid Microsphere) Injectable Suspension is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border.

The safety and efficacy of DEFINITY® with exercise stress or pharmacologic stress testing have not been established.

CONTRAINDICATIONS

Do not administer DEFINITY® to patients with known or suspected right-to-left, bi-directional or transient right-to-left cardiac shunts, by intra-arterial injection, or to patients with known hypersensitivity to perflutren.

IMPORTANT SAFETY INFORMATION

WARNING: Serious Cardiopulmonary Reactions 

Serious cardiopulmonary reactions, including fatalities, have occurred during or following perflutren-containing microsphere administration.

  • Assess all patients for the presence of any condition that precludes DEFINITY® administration (see CONTRAINDICATIONS).
  • In patients with pulmonary hypertension or unstable cardiopulmonary conditions, monitor vital sign measurements, electrocardiography and cutaneous oxygen saturation during and for at least 30 minutes after DEFINITY® administration (see WARNINGS).
  • Always have resuscitation equipment and trained personnel readily available.


In post marketing use, rare but serious cardiopulmonary or anaphylactoid reactions have been reported during or shortly following perflutren-containing microsphere administration (see ADVERSE REACTIONS). The risk for these reactions may be increased among patients with pulmonary hypertension or unstable cardiopulmonary conditions. It is not always possible to reliably establish a causal relationship to drug exposure due to the presence of underlying cardiopulmonary disease.
