Transcatheter aortic valve implantation (TAVI) has become the preferred treatment for severe aortic stenosis. Nonetheless, interplay between aortic valve disease, transcatheter valve implantation, and the coronary arteries is frequent and clinically relevant. Coronary intervention in the context of TAVI encompasses distinct but interrelated scenarios, including the management of concomitant coronary artery disease and the prevention or treatment of coronary artery obstruction. These aspects introduce additional complexity to procedural planning and long-term management. This review provides a comprehensive and practical overview of coronary interventions related to TAVI, encompassing coronary evaluation and physiological assessment, the indications and timing of percutaneous coronary intervention before and after valve implantation, and strategies for managing coronary obstruction. Particular emphasis is placed on anatomical and device-related factors influencing coronary access, including transcatheter heart valve design, aortic root anatomy, and commissural alignment. By structuring coronary interventions according to distinct clinical scenarios, this article aims to support tailored decision-making and optimise procedural safety, feasibility, and long-term coronary management in patients undergoing TAVI.
