INDICATION
DEFINITY® is indicated, after activation, for use in adult and pediatric patients with suboptimal echocardiograms to opacify the left ventricular chamber and to improve the delineation of the left ventricular endocardial border.
IMPORTANT SAFETY INFORMATION
BOXED WARNING: SERIOUS CARDIOPULMONARY REACTIONS
Serious cardiopulmonary reactions, including fatalities, have occurred uncommonly during or following perflutren-containing microsphere administration. Most serious reactions occur within 30 minutes of administration.
- Assess all patients for the presence of any condition that precludes DEFINITY® administration.
- Always have resuscitation equipment and trained personnel readily available.
