Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Alternative format of non-invasive diagnostic procedure - cardiac ultrasound
a) Robot-assisted echocardiographic examination
b) Procedure - Utilisation of existing clinically used cardiac ultrasound systems where system probe is held by robotic arm.
c) Delivery - Sonographer utilises a gamepad to control the robotic arm system to acquire images.

Any ultrasound system is permitted, and a specific vendor is utilised based on the discretion of the hospital.

Sonographers will undergo a minimum of 15 hrs of virtual (software-based only) and hand-on simulator training, prior to human echocardiogram scanning.

Standard operation manuals are provided to ensure correct and standardised use of the system.

All participants of the study will have previously undergone (prior to consent) a clinically required standard of care manual echocardiographic examination. The robotically assisted echocardiographic examination will be conducted within 72 hours of the manual scan.

Statistical methods / analysis
The proportion of RUAT (Robotic ultrasound assistance tool) echocardiograms deemed to be of sufficient quality will be summarised descriptively along with a 95% confidence interval.
Participant experience will be summarised descriptively.
Adverse events and serious adverse events will be coded using the Medical Dictionary for Regulatory Affairs and will be summarised by system organ class and preferred term by echocardiogram type (conventional vs RUAT Echo). No statistical comparisons between adverse events or serious adverse events by scan type are planned.
Adverse device effects will be coded using the FDA Medical Device Report (MDR) adverse event codes and will be summarised by Level 1 Term and Level 3 Term by echocardiogram type (conventional vs RUAT Echo).

Summary
Brief summary
This pilot study aims to investigate the safety and useability of robotically assisted echocardiographic examinations (echo). The technology is aimed to be deployed in any location (including regional and remote) and may be controlled remotely.
Should this study be successful it will allow access of essential standard of care to cardiac patients in remote and rural areas.
