Brief 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.

Outcome Measures
Primary Outcomes (1)
Acoustic index
Acoustic index during realtime and triggered imaging between compressed Definity or Lumason and activated Definity or Lumason
Data obtained at time of stress echo and all data will be acquired and study completed within 1 hour of stress echo or regular echo study. No follow up is needed or indicated.
Secondary Outcomes (1)
Clinical Adverse Events regarding reading of echocardiography
The data will be obtained within 30 minutes of the echocardiogram or stress echocardiogram. Any potential side effects will have occurred within this time frame as well.
Study Arms (1)
Single group, one arm study group
OTHERCompare echocardiograph imaging efficacy of active Definity or Lumason (perflutren lipid microsphere) with compressed Definity or Lumason.
Interventions
Definity and Lumason are tools for diagnosis used in echocardiography. Compare activated Definity or Lumason with compressed Definity or Lumason.
Eligibility Criteria
You may qualify if:
- years of age or older at screening
- Clinically indicated stress echocardiography to take place at the UNMC echocardiography laboratory
You may not qualify if:
- Prior allergic reaction to Definity® or Lumason
- Pregnant women
