DISsection RE-entry Evaluation With Absorb Bioresorbable Vascular Scaffolds in CTO. (DISCRETE-CTO)

October 14, 2016 updated by: Belfast Health and Social Care Trust

DISsection RE-entry Evaluation With Absorb Bioresorbable Vascular Scaffolds in Chronic Total Occlusion. The DISCRETE CTO Study.

Percutaneous Coronary Intervention (PCI) is increasingly effective to treat Chronic Total Occlusion (CTO) lesions in coronary arteries. This trial will examine modern dissection and re-entry approaches to treat more complex CTO lesions with the Absorb Bioresorbable Vascular Scaffold (BVS).

Detailed Description

This is a pilot study, with the aim of hypothesis generation. This research aims to establish the feasibility and safety of treating chronic total occlusions using dissection and re-entry techniques in combination with everolimus-eluting bioresorbable vascular scaffolds (Absorb BVS).

Primary aims of the study are:

  • To demonstrate a low rate of Target Vessel Failure (stent thrombosis, restenosis or late closure) at 12 and 24 months after CTO PCI and stenting with the Absorb BVS
  • To demonstrate a high degree of endothelial stent strut coverage at 12 and 24 moths after CTO PCI and stenting with the Absorb BVSThe primary outcome measure is
