This review systematically summarizes current devices and techniques for percutaneous recanalization of chronic total occlusions to aid interventional cardiologists in delivering safe and effective management.
Chronic Total Occlusion (CTO) has been considered as one of the "final frontier" in interventional cardiology. Until recently, the patients with CTO are often managed surgically or medically due to lack of published evidence of clinical benefits and lower success rate of percutaneous recanalization of CTO. However, the introduction of enhanced guidewires, microcatheters combined with novel specialized devices and techniques reduce the number of unapproachable CTO. In this review article, current techniques and devices of percutaneous recanalization of CTO have been systematically summarized, which may help budding interventional cardiologists to theoretically understand these complex procedures and to deliver safe and effective percutaneous management of CTO to the patients.

Bhargav Dave (2016) conducted a review in Chronic Total Occlusion (CTO). Percutaneous recanalization techniques and devices was evaluated. The introduction of enhanced guidewires, microcatheters, and novel specialized techniques has increased the success rate of percutaneous recanalization of chronic total occlusions to as high as 80%.
