Angiographically Based Direct Implantation of the Bioresorbable Vascular Scaffold in Non-ST Segment Elevation Acute Coronary Syndrome: Feasibility and Outcome.

Background: Direct implantation of metallic drug-eluting stents is recommended for lesions with high thrombotic burden; however, this can't be applied to bioresorbable scaffold for which adequate lesion preparation is recommended.

Aim: We aimed at assessing the feasibility and safety of direct scaffold implantation based only on angiographic assessment in patients presented with non-ST segment elevation acute coronary syndrome.

Methods: The study was a retrospective two-centre study conducted over patients diagnosed with NSTE-ACS presented to cardiology department at Juan Ramon Hospital, Spain and critical care department, Cairo University in the period between February 2016 to May 2017.
