Chronic Total Occlusion (CTO)


This study evaluated long-term results following successful endovascular therapy for chronic total occlusion below the knee using the retrograde approach after a failed antegrade approach.

We previously described the first real-world series of PCI involving Shockwave intravascular lithotripsy (S-IVL), including use in acute coronary syndromes and left main interventions. In this follow-up, we report the 1-year outcomes of patients treated with S-IVL during their PCI. 

Abstract: Background. The impact of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) on angina and subsequent incidence of major adverse cardiovascular event (MACE) rate remains controversial. Methods.

Long-term outcomes of patients with prior coronary artery bypass graft (CABG) surgery undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) have received limited study.
Angiography at 60 mo. post implantation of an Absorb bioresorbable vascular scaffold (Abbott Vascular) revealed a total occlusion at the distal scaffold. Within the proximal edge, OCT showed complete absorption of stent struts with a decreased mean scaffold area and diameter.
