Lately, importance of plaque modification prior to stent implantation, particularly use of cutting and scoring balloons, has been a subject of debate. Pre-treatment or plaque modification before stent implantation is important step to achieve best possible result and ensure long term safety and efficacy of PCI. The rationale behind plaque modification is that it may minimize arterial injury and subsequent neointimal proliferation and/or restenosis. Artery scoring before stent implantation gives almost perfect stent apposition with reduced inflation pressure, minimizes plaque shifting, prevents balloon slippage, alter calcification, increase artery compliance and enhance stent deliverability. Appropriate of use scoring balloons for plaque modification with subsequent stent implantation significantly increases acute and post procedural results of angioplasty. With bioabsorbable stents and bioresorbable vascular scaffolds plaque modification will be an essential tool to perform complete “vessel repair procedures”.
