Background: Coronary stenting has now become a gold standard to prevent or counteract narrowing
and obstruction of coronary vessels due to disease or injury. While the use of stents has been successful in this
situation, they are not without drawbacks and concerns. Restenosis and stent thrombosis after an interventional
procedure are the dreaded side effects resulting from the body’s natural response to a foreign object in the vasculature.
New developments in drug-eluting stents, such as biodegradable materials could mitigate some of the
problems like stent thrombosis, at least late stent thrombosis.
Methods: The goal of this work is to identify how the structural and design components of bio-resorbable scaffolds
(BRS) evolved and get translated into clinical outcomes. All the BRS articles were identified by an internet
based search and relevant articles were included in the review.
Results: The evolution of BRS from concept to current form is examined and the possible future course this field
might turn discussed.
Conclusion: The BRS field has evolved learning from DES terrain but this technology has its own advantages
and limitations. Newer generation of bio-resorbable scaffolds will be required to replace current generation of
technologically advanced DES.
