SonoVue®
SonoVue® is a second-generation ultrasound contrast agent, designed and optimized for pressure resistance: this is the result of many years of research and development within Bracco.
The research led to the selection of SF6, a gas with low solubility in blood for the gas phase of the microbubbles and a phospholipid monolayer for shell1,2,3. SonoVue® was approved in the European Union by a centralized procedure on 26 March 2001, and is currently marketed in 36 countries worldwide. Today, the possible clinical applications of CEUS are listed in the guidelines published by the Federation of European Ultrasound Societies (EFSUMB)4.

Important Safety Information on SonoVue® (8 microlitres/ml powder and solvent for dispersion for injection) Use in Critically ill Patients
SonoVue® (8 microlitres/ml powder and solvent for dispersion for injection) is an ultrasound contrast agent consisting of a suspension of tiny microbubbles (most microbubbles between 2 and 9 microns) with a unique structure made of an inert gas, sulphur hexafluoride, and a phospholipid shell that provides stability and prevents microbubble coalescence. When injected intravenously, SonoVue® strongly enhances the echogenicity of blood, which results in an improved signal-to-noise ratio.
Important New Safety Information
Following an evaluation of the benefits and risks of SonoVue® use in critically ill patients made to by the Committee on Human Medicinal Products (CHMP) of the European Medicines Agency (EMA), the decision was made to:
- delete the contraindications for SonoVue® use in patients with recent acute coronary syndrome or clinically unstable ischaemic cardiac disease, including: evolving or ongoing myocardial infarction, typical angina at rest within last 7 days, significant worsening of cardiac symptoms within last 7 days, recent coronary artery intervention or other factors suggesting clinical instability (for example, recent deterioration of ECG, laboratory or clinical findings), acute cardiac failure, Class III/IV cardiac failure, or severe rhythm disorders;
- to insert SonoVue® use information on these patient populations into the Special Warnings and Precautions for Use section of the Product Information.
Since its launch in 2001, four (4) cases of severe cardiac arrhythmia occurred following concomitant administration of SonoVue® and the direct-acting, inotropic agent dobutamine. Of note, these 4 cases occurred in patients with either ongoing myocardial infarction, or other factors suggesting clinical instability, acute cardiac failure, or severe rhythm disorders, where the use of dobutamine is specifically contraindicated. One case, occurred in a patient with dilated cardiomyopathy and severe heart failure. This patient experienced ventricular fibrillation and cardiac arrest during the stress-echo procedure; the adverse events were considered related to the administration of dobutamine by the reporter. In the further clinical course, the patient had multiple cardiac arrests and developed subsequent cardiac and multi-organ-failure. She died 19 days after the reported events.
In view of these rare events and the frequent use of dobutamine for stress echocardiographic procedures, the CHMP also decided to make sure SonoVue® is not used in combination with dobutamine in those patients for which the use of this pharmacologic stressor is contraindicated.
Therefore, the CHMP decided to add the following contraindication to the Product Information of SonoVue®:
"SonoVue® should not be used in combination with dobutamine in patients with conditions suggesting cardiovascular instability where dobutamine is contraindicated".
In summary:
- SonoVue® is no longer contraindicated in patients with recent acute coronary syndrome or clinically unstable ischaemic cardiac disease.
- Prescribers may use SonoVue® in this patient population using extreme caution, after a careful risk/benefit assessment and with close monitoring of vital signs during and after administration.
- SonoVue® should not be used in combination with dobutamine in patients with conditions suggesting cardiovascular instability where dobutamine is contraindicated.
To provide SonoVue® users and prescribers with this new important safety information, Bracco has agreed upon with EMA and sent out a "Dear Healthcare Professional Communication" (DHPC). This letter is intended to minimise any potential risk for the use of SonoVue® in critically ill patients, which may particularly benefit from more accurate diagnostic information obtained after administration of SonoVue®.
The original DHCP letter is attached.
Further Information

How to use it
Preparation of SonoVue®
SonoVue® is supplied in a kit containing a vial with phospholipids (lyophilised) in a sulphur hexafluoride atmosphere, a syringe pre-filled with physiological saline (0.9% saline solution) and a Mini-Spike transfer system. The suspension must be reconstituted before application. Reconstituting the microbubbles is not a difficult procedure but it is important to follow the instructions carefully in order to achieve the optimal effect of the contrast medium.
1. Connect the plunger by screwing it clockwise into the syringe.
2. Open the MiniSpike transfer system from the blister pack and remove the syringe cap.
3. Open the transfer system cap and connect the syringe to the transfer system by screwing it in clockwise.
4. Remove the protective disc from the vial. Insert the vial into the transparent sleeve of the transfer system and press firmly to lock the vial in place.
5. Empty the contents of the syringe into the vial by pushing on the plunger.
6. Shake vigorously for 20 seconds to mix all the contents of the vial into a homogeneous milky liquid.
7. Reverse the system and carefully aspirate SonoVue into the syringe.
8. Unscrew the syringe from the transfer system.
Important: do not use if the liquid obtained is not clear and/or if solid parts of the lyophilizate are visible in the suspension.

- Preparation and Reconstitution
Indications
SonoVue® is used in ultrasound imaging to increase the echogenicity of blood, which in turn leads to an improvement in the signal-to-noise ratio5.
Echocardiography
SonoVue® is an echocardiographic contrast agent that passes through the pulmonary circulation: it is indicated in patients with suspected or established cardiovascular disease to opacify the cardiac chambers and improve visualisation of the endocardial margins of the left ventricle5.
Doppler examination of microvasculature
SonoVue® improves diagnostic accuracy in detecting or excluding changes in cerebral arteries, extracranial carotid arteries, and peripheral arteries by improving Doppler signal-to-noise ratio.
SonoVue® improves Doppler flow image quality and duration of clinically useful signal enhancement in portal vein assessment5.
SonoVue® improves visualization of the vasculature of liver and breast lesions during echo-Doppler examination, thus allowing more specific lesion characterisation5.
Focal liver lesions
SonoVue® in the characterisation of focal liver lesions:
- very good results in terms of efficacy and comparable to CT and MRI6,7,8,9,10
Ultrasound of urinary excretory tract
SonoVue® is indicated for use in ultrasound of the urinary excretory tract in paediatric patients, from birth to 18 years of age, to detect the presence of vesicoureteral reflux. literature reference5
SonoVue® in endocardial border definition
- baseline echocardiography significantly underestimates left ventricular volumes compared to cine ventriculography and cardiac MRI11
- contrast echocardiography is particularly useful when a reproducible and accurate measurement of left ventricular function is required12
