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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
ACIST Medical Systems Monorail Pressure Sensor (MPS) Catheter. Using standard inverventional catheter placement techniques, MPS catheter's pressure sensor is placed just distal to a vessel stenosis and measures the distal blood pressure. In combination with the aortic pressure measured from the hospital's hemodynamic monitor, the MPS system's console displays the aortic and distal blood pressures and calculates fractional flow reserve (FFR).

In a single procedure expected to last under an hour, both the MPS and the Radi PressureWire are introduced into the vessel and measurements are made from both systems, using a nonrandomized crossover trial design, as close together in time as possible.

The MPS system differs from the Radi PressureWire in that it is mounted on a Monorail catheter.

Radi PressureWire. Using standard inverventional catheter placement techniques, Radi pressure wire is placed just distal to a vessel stenosis and measures the distal blood pressure. In combination with the aortic pressure measured from the hospital's hemodynamic monitor, the MPS system's console displays the aortic and distal blood pressures and calculates fractional flow reserve (FFR).
