Key result
Percutaneous coronary intervention for chronic total occlusion may improve angina relief and heart function, utilizing new wires, microcatheters, and intravascular ultrasound guidance.
Why the study?
Chronic total occlusion accounts for 10%-20% of all PCI procedures, and the current status of PCI techniques and devices for these lesions requires description.

This review summarizes current devices and techniques for PCI of chronic total occlusions, highlighting potential benefits for angina relief and heart function.
This paper describes the current status of percutaneous coronary intervention (PCI) for totally occluded coronary arteries. Chronic total occlusion is associated with 10%-20% of all PCI procedures. Results show that opening an occluded vessel, especially one supplying a considerable area of myocardium, may be beneficial for a patient's angina relief and heart function. We describe the devices used currently in re-canalization such as new wires, microcatheters (including Tonus and Cosair) and intravascular ultrasound guidance. Different techniques to improve the success rate and reduce complications are discussed in detail.
