Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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
Treatment: Devices - Oversized stent deployed at low pressure (Multi-Link Bare Metal Stent or Xience Prime Evenolimus Eluting Stent)
Treatment: Devices - Stent deployed at high pressure (Multi-Link Bare Metal Stent or Xience Prime Evenolimus Eluting Stent)

Active comparator: Stent oversize group - Oversized stent deployed at low pressure:

A stent premounted on a balloon with a nominal diameter halfway between the lumen diameter and the true vessel diameter (approximated by external elastic lamina) as assessed by IVUS. This will be based on the smallest of the vessel reference diameters proximal and distal to the lesion. In addition the vessel diameter must be greater than this diameter throughout the length of the lesion. This stent will be implanted at an inflation pressure of 10 atmospheres or less for at least 15 seconds and a second IVUS will be performed to assess the end point.

Active comparator: High pressure group - Stent deployed at high pressure:

A stent premounted on a balloon with a nominal diameter approximately equal to the vessel segment lumen reference diameter as previously assessed by IVUS will be used. This stent will be implanted at an inflation pressure of 14 atmospheres or more for at least 15 seconds and a second IVUS will be performed to assess the end point


Treatment: Devices: Oversized stent deployed at low pressure (Multi-Link Bare Metal Stent or Xience Prime Evenolimus Eluting Stent)
Stent can include both bare metal stents and drug eluting stents. Depending on availabilities, different stent brands may be used.
