NCT02237456

Brief Summary

The purpose of this study is to compare optical coherence tomography (OCT) scans performed in the same coronary artery with two different OCT systems (Lunawave and OPTIS) before and after implantation of stents or bioresorbable scaffolds.

Sampling MethodProbability Sample
Study Population

Consecutive patients undergoing percutaneous coronary intervention (PCI) at Department of Cardiology, Aarhus University Hospital Skejby, will be invited to participate in the study. 12 patients will be included; 4 with acute ST-elevation myocardial infarct (STEMI) and 8 stable or stabilized patients.

You may qualify if:

  • Indication for intervention with PCI on the right or left coronary artery
  • Age \>18 years
  • Must be able to give written informed consent

You may not qualify if:

  • Expected life span of less than one year
  • Pregnancy or possible pregnancy
  • Cardiogenic shock
  • Especially tortuous vessels
  • Renal impairment (creatinine\> 100 micromoles / L)
