What is Perflutren Protein Type A Microspheres

Perflutren protein type A microspheres is an intravenous diagnostic agent used with ultrasonography to produce an echogenic contrast effect in the blood. Specifically, perflutren protein type A microspheres is indicated for administration to patients with suboptimal echocardiograms to enhance visualization of left ventricular endocardial borders.

Perflutren is an octafluoropropane, a fluorocarbon gas, that is encapsulated within an albumin shell to optimize the size of the gas bubble (2 to 4.5 micrometers) and improve stability.

During ultrasound examination, the gas-filled microspheres produce a lower impedence to the acoustic waves than does the surrounding blood, resulting in ultrasound waves that are scattered and reflected at the microsphere-blood interface. In addition, at frequency used during echocardiograms (2 to 5 MHz), the microspheres resonate which further increases the ultrasound scattering and reflecting.

The ultimate effect is enhanced visualization of the ultrasound image.

Prior to drug administration, ensure resuscitation equipment and trained personnel are readily available.

Perflutren protein type A microspheres is associated with serious cardiopulmonary adverse reactions.

Perflutren protein type A microspheres was FDA-approved in 1997
