To detect coronary artery disease by both coronary and carotid artery imaging and myocardial perfusion imaging using a new low mechanical index real time system.

Condition Intervention
Coronary Stenosis
Carotid Stenosis
Myocardial Reperfusion
Drug: Optison
Drug: Definity

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: The Detection of Coronary Stenosis With Intravenous Mircrobubbles and Contrast Pulse Sequence Low Mechanical Index Imaging

Further study details as provided by University of Nebraska:

Primary Outcome Measures:
  • To determine whether this imaging scheme can detect both coronary and carotid artery stenoses as well as perfusion defects during a standard echocardiographic examination [ Time Frame: 2-4 months ]

Secondary Outcome Measures:
  • Visually analyze the coronary and carotid arteries as well as perfusion defects during a standard echocardiogram examination [ Time Frame: immediate ]

Enrollment: 0
Study Start Date: February 2012
Estimated Study Completion Date: March 2014
Estimated Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1

Administration of Optison (0.1-0.4 mL) intravenously followed by Contrast Pulse Sequencing to image both the coronary and carotid arteries.

Use will depend on availability of the contrast for the given study Optison will not be used on patients with blood allergies or Jehovah Witnesses

Drug: Optison
0.1-0.4 mL through intravenous injection at the beginning of the study.
Active Comparator: 2
Intravenous injection of Definity (0.05-0.20 mL) followed by Contrast Pulse Sequencing to image both coronary and carotid arteries
Drug: Definity
intravenous injection at 0.05-0.20 mL
Active Comparator: 3
intravenous Injection of PESDA at a rate of 0.05-0.20 mL followed by image of coronary and carotid arteries PESDA will be used exclusively in patients who are eligible for other IRB studies
intravenous injections dosage 0.05-0.20 mL
Other Name: PESDA is an investigational drug (IND 54,263)

Detailed Description:
The objective of this clinical study will be to visualize both coronary and carotid arteries as well as detect myocardial perfusion following a routine intravenous injection of Definity (0.05-0.20 millimeters), Optison (0.1-0.4 millimeters) or PESDA (0.05-0.2 mL). Following these injections , we will attempt to Contrast Pulse Sequencing on the Siemens Acuson Sequoia system to image both the coronary and carotid arteries, as well as the Myocardial perfusion.

Ages Eligible for Study:   19 Years and older   (Adult, Senior)

  • last eight patients will be diabetics who smoke
  • provide informed consent after receiving a verbal and written explanation of the purpose and nature of the study

Exclusion Criteria:

  • severe valvular heart disease by Doppler Echocardiography
  • females of child-bearing potential who are not taking a medically approved method of birth control will be excluded. If the patient is pregnant she will be excluded.
  • patients who are allergic to blood or blood products will be excluded
  • have contraindication to Optison, Definity, or PESDA (pulmonary HTN, cardiac shunt)
  • non diabetics, non smokers
