Key result
BASILICA enables successful valve-in-valve TAVR with preserved coronary flow and access.
Why the study?
The feasibility and outcomes of the BASILICA procedure prior to valve-in-valve TAVR in a supra-annular TAV prosthesis had not been reported.
Case Report (n=1)
Offers potential option for coronary protection during supra-annular TAV reintervention; extends BASILICA applicability but remains hypothesis-generating.
An 80-year-old man with a supra-annular transcatheter aortic valve (TAV) prosthesis presented with severe transvalvular aortic regurgitation 18 months after the TAV replacement procedure. The authors report the first ever valve-in-valve procedure using BASILICA (bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) in such a supra-annular TAV prosthesis. Minimal paravalvular leakage, normal coronary artery flow, and easy coronary access were seen postimplantation. (Level of Difficulty: Advanced.)

Damlin et al. (2023) conducted a case report in Severe transvalvular aortic regurgitation in a supra-annular TAV prosthesis (n=1). Valve-in-valve procedure using BASILICA was evaluated on Procedural success (minimal paravalvular leakage, normal coronary artery flow, easy coronary access). A valve-in-valve procedure using BASILICA in a supra-annular TAV prosthesis was successfully performed, resulting in minimal paravalvular leakage, normal coronary flow, and easy coronary access.
