Coronary obstruction is a life-threatening complication of transcatheter aortic valve replacement. Bioprosthetic or native aortic scallop intentional laceration to prevent iatrogenic coronary artery obstruction (BASILICA) seems to be an effective approach for preventing coronary obstruction by maintaining blood flow towards the coronary artery by an intentionally created leaflet laceration. In this report, we aimed to provide step-by-step guidance on how to perform a BASILICA procedure. The technique includes several steps that can be challenging without proper guidance. Assistance by operators who have already performed BASILICA seems to be crucial, and formal proctorship during initial procedures can ensure good clinical outcomes.
