摘要

Transcatheter aortic valve implantation (TAVI) is a safe and effective procedure for the treatment of aortic stenosis. With the recently broadened indications, there is a larger cohort of patients likely to outlive their first transcatheter heart valve (THV). This review discusses relevant lifetime planning considerations, focusing on the utility of preprocedural computed tomography imaging to help implanters future-proof their patients who are likely to outlive their first valve. The initial priority is to optimise the index procedure by maximising THV haemodynamic function and durability. This involves maximising the effective orifice area, minimising the risk of new pacemaker implantation, reducing paravalvular regurgitation, and preventing coronary obstruction and annular rupture. In patients requiring a second valve procedure, a significant proportion will require a TAVI-in-TAVI, and implanters should consider the key priorities for a redo procedure, including the increased risks of patient-prosthesis mismatch and conduction abnormalities, promoting coronary reaccessibility, and preventing coronary obstruction and sinus sequestration. Careful planning can identify potential hurdles as well as predict the feasibility and likely outcomes of redo-TAVI, to help individualise care over the lifetime of each patient.
