Drug-coated balloon without stent implantation for chronic total occlusion of coronary arteries: description of a new strategy with an optical coherence tomography responce
Chronic total occlusion (CTO) revascularization of coronary arteries is often a complex intervention whose success is lower than other percutaneous interventions. The reason for this uncertainty is related to the more complex anatomical setting and the increased risk of complications . Moreover, this intervention is burdened by higher use of X-rays, contrast media and higher costs. On top of these informations, the most recent scientific data show how an effective CTO revascularization improves the prognosis reducing the risk of cardiac mortality and major adverse cardiovascular events (MACE) if compared to medical therapy [2,3].
