The “chimney” and “BASILICA” techniques1,2 were developed to offer safe prevention of coronary artery occlusion (CAO) in case of valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) in degenerated surgical bioprostheses. However, sometimes these lead to unnecessary stenting or may simply not be performed because of unfavourable anatomy. Moreover, when they are not implemented, a reassuring coronary angiogram after valve implantation may hide the risk of delayed CAO, which could occur after the removal of protective wires from coronaries3.
This study aimed to evaluate the feasibility and usefulness of intravascular ultrasound (IVUS) analysis of ...
