Chronic Total Occlusion (CTO)

Featured

The aim of our study was to look at the viability of myocardium in patients with CTOs in both infarct-related and non-infarct related occluded vessels with grade 3 collaterals.
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.
The impact of intravascular ultrasound utilization for stent optimization on the long-term outcomes in chronic total occlusion percutaneous coronary intervention has received limited study.

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.
