Key result
IVUS assessment of coronary ostia after valve-in-valve TAVI lacks reported results.
Why the study?
The chimney and BASILICA techniques to prevent coronary artery occlusion during valve-in-valve TAVI may lead to unnecessary stenting or be omitted due to anatomy, and coronary angiograms may not reveal delayed occlusion risk after valve implantation.
Observational
Intravascular ultrasound may offer a feasible and useful method to assess coronary ostia and prevent delayed coronary artery occlusion following valve-in-valve transcatheter aortic valve implantation.
Truncated reporting leaves IVUS utility for coronary ostia after valve-in-valve TAVI unaddressed; prospective studies needed.
Introduction 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 ...
