Following the introduction in the latest European and American guidelines, transcatheter edge‐to‐edge repair has become a valid alternative to surgery for ineligible patients. Among the available technologies, MitraClip (Abbott) was the first to be introduced for the percutaneous treatment of mitral regurgitation with the edge‐to‐edge technique. Although its safety and effectiveness has been widely demonstrated, the optimal procedural results are highly dependent from operators' experience. In this manuscript, we provide a full guide of advanced steering maneuvers of MitraClip in different scenarios of transseptal puncture.
