Summary

Chronic total occlusion is defined as thrombolysis in myocardial infarction (TIMI) flow grade 0 with an estimated duration of at least 3 months. The interest in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has increased, but with failure rate up to 20%, leading to important developments in dedicated equipment and techniques.

In the 2014 European Guidelines on Myocardial Revascularization, intravascular ultrasound was recommended to guide stent implantation in selected patients, and this recommendation was a class IIa/level of evidence B.

In CTO PCI, certain angiographic features such as blunt proximal CTO cap, tortuosity, heavy calcification, and lack of visibility of path in the distal vessel increase procedural difficulty

Conditions

  • Coronary Occlusion

Interventions

DEVICE

intravascular ultrasonography

intravascular ultrasonography will be used during the study for the resolving proximal cap ambiguity of chronic total occlusion, facilitating re-entry into the true lumen after subintimal crossing and confirming distal true lumen guidewire position
