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…

Bubble trouble: aortic air embolization and de-embolization during coronary angiography

09 Aug 2021

Air embolism (AE) is a rare complication during interventional procedures and one of the most scaring for interventional cardiologists. Air bubbles in the coronary circulation often result in ischemic symptoms, vasospasm, and even cardiac arrest. In addition, arrhythmias are common and closely related to the coronary ...
