DEFINITY® Improves Cardiac Diagnosis and Patient Management1

DEFINITY® has been shown to alter patient management decisions, leading to significant changes in medications, procedures, or both1

DEFINITY® reduces the number of diagnostic procedures conducted, decreases length of stay, and lowers the per-patient expense1

Enhanced Echocardiography: It's What You Don't See That Matters

Ben Lin, MD, Theresa Green, RDCS, and Sean McMahon, MD, present the Lantheus 2019 ASE Science & Technology Theater Program.

How DEFINITY® Works

DEFINITY® microbubbles are composed of octafluoropropane gas encapsulated by a synthetic phospholipid shell.7

The microbubbles effectively traverse the pulmonary vasculature to produce high-quality, consistent, and reliable images of the left ventricle.7-10

The DEFINITY® microbubble diameter of 1.1 to 3.3 microns is smaller than normal red blood cells.7,11

DEFINITY® Delivers High-Quality Images

DEFINITY® is the only ultrasound enhancing agent with mechanical activation.7,12,13 DEFINITY® is activated in VIALMIX® RFID, which contributes to consistent image quality.7,9

INDICATIONS

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

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 [see Contraindications (4)].
  • Always have resuscitation equipment and trained personnel readily available [see Warnings and Precautions (5.1)].
