摘要

Chronic total occlusion (CTO) occurs in approximately 20％ known coronary atherosclerotic lesions,and CTO intervention has become a most challenging work.Although retrograde techniques have been applied and significantly increased the success rate of CTO intervention,there are still some CTOs that cannot be opened.In this letter,we report a CTO intervention that both antegrade and retrograde reverse controlled antegrade and retrograde subintimal tracking (CART) techniques failed.However,a new intravascular ultrasound (IVUS) guided technique was proposed and successfully re-opened the left circumflex (LCX)CTO.
