About this study

This study will evaluate the 3 drug-eluting stents presently marketed for intervention in the coronary artery with respect to the complications that may occur in case it becomes necessary to retract the stent during the intervention. It has been noted that stents carrying a drug for local application may be more difficult to retract than the more smooth bare metal stents.

Read the detailed description

Patients in whom DES implantation is planned will be randomized to one of the 3 commercially available stents (i.e., Cypher, Taxus-Liberté, Endeavor).

Sealed envelopes will be used for randomization purposes. Should additional stents be required in the same patient for the same or other lesions, another stent of the same type of stents will be implanted.

The following assessments will be made:

  • Unblinded subjective operator assessment based on a questionnaire. The questionnaire will include questions on problems encountered during stent-balloon retrieval, special maneuvers performed (e.g., retrieval of the catheter during device removal, and possible complications associated with device retrieval).
  • Blinded measurements of following parameters:
  1. Minimal and maximal distance between the tip of the guiding catheter and the proximal stent end during stent-balloon retrieval.
  2. Minimal and maximal distance between the tip of the guidewire and the distal portion of the stent during stent-balloon retrieval.
  3. To do so the retrieval of the stent-balloon will be documented on ciné-angiography. The measurements will be performed by a qualified technician/physician blinded to the type of device used.
  • Clinical endpoints:
  1. In-Hospital mortality, myocardial infarction, or need for unplanned urgent repeat revascularization.
  2. Myocardial infarction defined as creatine kinase MB-isoform [CK-MB] ≥3x upper limit of normal within 24 hours of the procedure or ≥2x upper limit of normal after 24 hours of the procedure in the presence of new ischemic symptoms.
  • Target enrollment of 150 patients

Questions about this trial

What is this clinical trial studying?

A study testing Percutaneous coronary intervention in people with Coronary Artery Disease, run by Foundation for Cardiovascular Research, Zurich.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Jan 2006. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Marco Roffi, MD (+41 44 255 8573, marco.roffi@usz.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

In-Hospital mortality, myocardial infarction, or need for unplanned urgent repeat revascularization.. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2006.
