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.
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
||The Detection of Coronary Stenosis With Intravenous Mircrobubbles and Contrast Pulse Sequence Low Mechanical Index Imaging
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 ]

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
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
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)
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.
