CTO History (Supervised by Osamu Katoh M.D.)

Dr. Osamu Katoh, the leading global authority on CTO-PCI, said “CTO guidewires have reached one goal.”
This video, which contains a total of five chapters, introduces the evolution of the treatment methods and various devices that were developed along with it while following the history from the rise of the concept of PCI treatment against CTO to the present when the rate of treatment success exceeds 90%. You can deepen your understanding about the essence of CTO and the mechanism of the treatment devices through this video.
(Guest appearance: Takahiko Suzuki M.D., Director of Toyohashi Heart Center)
