Exclusion criteria: - Hypersensitivity to the active substance(s) or any of the excipients in SonoVue - Right-to-left cardiac shunt - Severe pulmonary hypertension (pulmonary artery pressure > 90mmHg) - Uncontrolled systemic hypertension - Adult respiratory distress syndrome - Severe pulmonary disease (e.g. COPD GOLD 3/4, adult respiratory distress syndrome) - Clinically unstable cardiac disease (recent or ongoing myorcardial infarction, unstable angina at rest, clinically worsening cardiac symptoms, severe cardiac arrythmia*s, etc.) - Loss of renal function (GFR

Design outcomes

Primary

Measure	Time frame
Vector velocity fields derived from the echo PIV data will be used to calculate and visualize the velocity profile.	—

Secondary

Measure	Time frame
Vector velocity fields derived from computational fluid dynamics (CFD) data will be used to calculate and visualize the velocity profile and to validate the echo PIV results. Furthermore the wall shear stress (WSS) and the oscillatory shear index (OSI) will be calculated from both the echo PIV as the CFD data. Specific flow patterns, e.g. recirculation or blood stasis, will also be analysed.	—
