What this Trial Is About
Objective of this study is to 1) analyze the clinical, anatomical and periprocedural differences of patients who underwent a procedure related to coronary CTO through the antergrade approach and retrograde approach; 2) analyze the success rate of the procedures and the incidence and patterns of complications; 3) compare and analyze long-term performances after the successful procedure; and 4) identify the independent factors that require a retrograde approach and the prognostic factor regarding long-term performances after use of each approach.
