Study Summary
Use of Reactivated DEFINITY® in or LUMASON Patients Undergoing Rest or Stress Echo Purpose of the study: Each patient undergoing a rest or stress echocardiogram uses a full vial of DEFINITY® or LUMASON contrast agent. During infusion, this often condenses back to its liquid phase due to manual pressure applied in the syringe. At this point, it is not optimal to be used at current ultrasound settings for stress echocardiography. This research project will test whether this condensed DEFINITY® or LUMASON can be reactivated by ultrasound using the same transducer used to image the patient. Eligibility: Same criteria as required for stress echo procedure. Interventions and Evaluations: Inject condensed DEFINITY® or LUMASON at end of stress test Follow Up: The patient would be observed by echo lab staff for half an hour following completion of the stress test. There would be no longitudinal follow up.
Primary Outcome
Acoustic index during realtime and triggered imaging between compressed Definity or Lumason and activated Definity or Lumason
Interventions
- OTHER perflutren lipid microsphere
