Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patient is clinically indicated for a saline contrast TTE study with a suspected right-to-left shunt
• Patient must be at least 18 years of age inclusive, at the time of signing the informed consent
• Able to communicate effectively with trial personnel

You may not qualify if…

• Female patients who are pregnant or lactating. All women of child-bearing potential (WOCBP) must have a negative urine pregnancy test at screening regardless of contraceptive use history
• WOCBP are excluded unless they have been using an adequate and medically approved method of contraception to avoid pregnancy for at least 1 month prior to ASI-02 dose administration
• Allergy to polysorbate 80 (PS-80)
• American Society of Anesthesiologists (ASA) physical status classification IV, V, or VI, except that participants with ASA physical status IV due solely to recent suspected transient ischemic attack or cerebrovascular accident are eligible for inclusion
• Current illness or pathology that in the opinion of the investigator would prevent undergoing investigational product administration due to a significant safety risk to the patient
• Uncontrolled arterial hypertension (defined as systolic blood pressure ≥ 200 mmHg or diastolic blood pressure ≥ 110 mmHg) or arterial hypotension (defined as systolic blood pressure ≤ 90 mmHg)
• Unstable cardiovascular status defined as:
• myocardial infarction or unstable angina pectoris within 6 months prior to procedure day
• symptomatic valvular heart disease or moderate to severe stenotic valvular heart disease
• clinically significant congenital heart defects (excluding an atrial septal defect [ASD], patent foramen ovale [PFO], or pulmonary arteriovenous malformation [PAVM])
• current uncontrolled cardiac arrhythmias causing clinical symptoms requiring medical intervention or hemodynamic compromise
• acute pulmonary embolus or pulmonary infarction
• acute myocarditis or pericarditis
• acute aortic dissection
• untreated atrial fibrillation
• Any major surgery within 30 days prior to screening
• Participation in any investigational drug, device, or placebo study within 30 days prior to screening
• Vulnerable adult participant populations (e.g., incarcerated or cognitively challenged adults)
