'Miracle stents' - a future without restenosis
McGill Journal of Medicine, 2020 Over the last three decades, percutaneous coronary intervention (PCI) technology has revolutionized the field of cardiology. PCI began in the form of balloon angioplasty, and was followed by coronary stenting.

Coronary arterial aneurysm formation after balloon angioplasty
The American Journal of Cardiology, 1983 The mechanism of coronary stenosis dilatation by percutaneous transluminal coronary angioplasty (PTCA) is incompletely understood. Five men who developed coronary arterial aneurysms at the site of PTCA are described. All patients were in New York Heart Association functional class III or IV at the time of PTCA. In 2 patients acute myocardial infarction

Bioabsorbable Endovascular Adhesive Tape (BEAT) for Improving Vascular Regeneration
Advanced Science, EarlyView.A bioabsorbable endovascular adhesive tape (BEAT) platform based on a hierarchical polyelectrolyte complex is developed to enhance drug delivery in the DCB system. The coating enables rapid transfer to the vessel, provides short‐term mechanical support, and promotes both immediate transfer and long‐term retention of drugs at the lesion site.
