Coronary Artery Aneurysm After Everolimus-Eluting Bioabsorbable Vascular Scaffold Implantation

Coronary Artery Aneurysm After Everolimus-Eluting Bioabsorbable Vascular Scaffold Implantation.

A mong the rare complications after percutaneous coronary intervention, coronary artery aneurysms (CAA) reportedly have an incidence of 0.3% to 6.0%. The detection of CAAs vary from 3 days to up to 4 years after drug-eluting stent (DES) and from 6 days to up to 6 years after baremetal stents (BMS) implantation. Associated factors include residual dissection and deep arterial wall injury caused ...

Coronary Artery Vessel Healing Pattern, Short and Long Term, After Implantation of the Everolimus‐Eluting Bioresorbable Vascular Scaffold

BACKGROUND Although the Absorb bioresorbable vascular scaffold is increasingly used in daily clinical practice for the treatment of coronary artery disease, the exact vascular healing pattern and the resorption process in humans is unknown because histological data are derived only from animal studies. METHODS AND RESULTS We have obtained 4 autopsies (5 scaffolds) since August 2013. Duration ...

Coronary aneurysm after drug-eluting stent implantation.

The use of drug-eluting stents aiming at by-pass the disadvantage of stainless steel stents have been associated to late thrombosis after withdrawal of anti-platelet agents. We report a case with another complication, the development of a coronary aneurysm in the stent area more than three years after index procedure. Late chronic local inflammatory responses may be responsible for the weakenin...

Long-Term Follow-Up of Patients after Percutaneous Coronary Intervention with Everolimus-Eluting Bioresorbable Vascular Scaffold

Background: Bioresorbable vascular scaffolds (BVS) were developed to improve the long-term results of percutaneous coronary intervention, restoring vasomotion. Objectives: To report very late follow-up of everolimus-eluting Absorb BVS (Abbott Vascular, Santa Clara, USA) in our center. Methods: Observational retrospective study, in a single Brazilian center, from August 2011 to October 2013,...
