Key result
BASILICA technique successfully prevents coronary obstruction during valve-in-valve TAVI without 90-day complications.
Why the study?
Obstruction of coronary ostia is a rare but devastating complication of TAVI, especially in valve-in-valve procedures, and BASILICA is a new technique to prevent it.
Case Report (n=1)
No
This first reported case of the BASILICA technique in Chile demonstrates its feasibility and safety in preventing coronary obstruction during a high-risk valve-in-valve TAVI procedure.
Supports BASILICA feasibility in select valve-in-valve TAVI; leaves open need for prospective studies before wider adoption.
Resumen El implante de la válvula aórtica transcateter (TAVI) es una alternativa eficaz en pacientes con estenosis aórtica severa de r de riesgo quírúrgicoquirúrgico alto a intermedio. La obstrucción coronaria es una complicación rara pero devastadora con una mortalidad cercana al 50%. Ocurre cuando se desplaza el velo valvular obstruyendo los ostia coronarios. Es 4 veces más común en el implante de TAVI sobre una prótesis valvular quirúrgica biológica (valve in valve: ViV). La laceración intencional del velo coronariano para prevenir la obstrucción iatrogénica de la arteria coronaria (BASILICA) del acrónimo bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction) es una técnica nueva para prevenir esta complicación. Presentamos el caso de un hombre de 83 años con reemplazo valvular aórtico EPIC #25 y disfunción protésica luego de 10 años. Presentaba un alto riesgo quirúrgico para recambio valvular aórtico por lo que se efectúa TAVI con técnica BASILICA de forma exitosa.

M. et al. (2026) conducted a case report in Severe aortic stenosis and prosthetic valve dysfunction (n=1). TAVI with BASILICA technique was evaluated on Procedural success and absence of coronary obstruction. TAVI using the BASILICA technique was successfully performed to prevent coronary obstruction during a valve-in-valve procedure, resulting in no complications at 90 days.
