Absence of Clinically Significant Increase in Pulmonary Artery Pressure After Intravenous Perflutren Injection for Myocardial Perfusion Imaging in Pigs

A continuous intravenous infusion of perflutren at a rate achieving optimal, sustained myocardial perfusion imaging in pigs induces a mild, transient, not clinically significant increase in pulmonary artery pressures without affecting heart rate or systemic arterial pressures.
