Percutaneous coronary intervention (PCI) for the treatment of coronary artery disease (CAD) is the most commonly performed cardiovascular procedure and one of the most frequently performed therapeutic interventions in medicine [1]. Drug-eluting stents (DES) were introduced to address the limitations of bare-metal stents (BMS) and are now considered the default therapy for patients undergoing a PCI procedure, regardless of their clinical presentation, lesion subtype or comorbidities [2–4[1]]. Newer generation DES were aimed at improving the balance between safety and efficacy through a better stent design, polymer biocompatibility and optimized drug release. These improvements are concerning:

Novel metallic alloys (cobalt–chromium and platinum–chromium) with thinner stent struts (50–90 μm) to enhance hemodynamic flow and drug ...
