Atherosclerotic and fibrotic plaques in this area contain an abundance of smooth muscle, collagen, and a certain degree of calcification, along with thicker adventitia. Additionally, it has certain anatomical aspects such as poor…
Thin vs. Ultrathin Stents: 1-Year Clinical Results After IVUS/OCT-Guided Implantation
Second generation drug-eluting stents have lower frequency of thrombotic complications and in-stent restenosis. While clinical results have significantly improved, having a 2-3% annual rate of these complications within the first year after angioplasty is still worrisome. This resulted in the development of stents with struts <70 µm (ultrathin), with bioresorbable polymer and abluminal cover. Stents…
