Major

Perflutren (applies to Definity) cardiopulmonary reactions

Major Potential Hazard, Moderate plausibility. Applicable conditions: Myocardial Infarction, Congestive Heart Failure, Ventricular Arrhythmia

Serious cardiopulmonary reactions including fatalities have uncommonly occurred during or shortly following perflutren- containing microsphere administration, typically within 30 minutes of administration. The risk may be increased among patients with unstable cardiopulmonary conditions such as acute myocardial infarction, acute coronary artery syndromes, worsening or unstable congestive heart failure, or serious ventricular arrhythmias. Always have cardiopulmonary resuscitation personnel and equipment readily available prior to perflutren administration and monitor all patients for acute reactions.
