CTO (Chronic total occlusion)

Find all the latest content on chronic total occlusion (CTO) published on this website.

Recently we have seen an increase in successful percutaneous coronary interventions (PCI) of CTO in part due to improvements in hardware (guidewires and balloons), the introduction of dedicated devices (microcatheters, channel dilators, dissection-reentry devices) and the elaboration of CTO-specific techniques. To fully grasp CTO today, here you will find here everything that you need to know including the latest devices and techniques as well as advances in imaging, the use of adjunctive pharmacotherapy, vascular access or understanding bleeding risks…

Planning of CTO PCI based on initial angiogram

16 May 2023 – From EuroPCR 2023

View the case of a man with severe inferior ischemia and right coronary occlusion at the proximal and mi-parts, & follow discussion about how to approach the CTO, before analyzing the one of a 62-year-old man with anterior STEMI and elective PCI Cx, HTN, hyperlipidemia, LVEF...

Anterograde LAD CTO - LIVE case

03 Mar 2023 – From AfricaPCR 2023

A 66-year-old male presented an ACS two months ago with MVD, preserved LV function without regional wall abnormality. The medical team decided to address this condition with a double PCI: one in the mid-RCA and another in the distal CX. Their plan includes performing PCI of the LAD CTO.
During the procedure, the operators...

Bifurcation and CTO clinical cases

03 Mar 2023 – From AfricaPCR 2023

This session presents several challenging clinical cases including an in-stent restenosis in a bifurcation and retained wire, a left main thrombus, and an open CTO for retrograde approach of another CTO. Watch now to find out more!
