Evaluation With OFDI of Strut Coverage of Terumo New Drug Eluting Stent (Development Code TCD-10023) With Biodegradable Polymer at 1, 2 and 3 Months
Abstract
Purpose of this study is to evaluate, after implantation of a drug eluting stent (DES), coverage of the stent struts by new tissue. The evaluation will be performed by means of intravascular imaging technology (optical frequency domain imaging, OFDI). Renewed tissue coverage over the implanted stent struts prevents direct contact between blood and metal/polymer, which could lead to adverse events: patients need to take blood-thinning drugs to prevent these events. Ous new stent has drug and polymer only on the outside of the stent, and the polymer is degraded by the body leaving a bare metal stent after 3-4 months. This should allow fast coverage of the struts, and might allow to reduce duration of the supportive medical treatment. Our hypothesis is that \<20% of the struts remain uncovered at 3 months after implantation, as assessed by OFDI.
Conditions: Coronary Artery Disease.
Primary outcome: OFDI assessed percent stent strut coverage.
Enrollment: 60 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 60 participants or records.
