Transcatheter aortic valve implantation in the elderly: an umbrella review

Aim: The management of aortic stenosis has seen momentous changes thanks to the introduction of transcatheter aortic valve implantation (TAVI, i.e., transcatheter aortic valve replacement). Indications to TAVI have expanded progressively to intermediateand low-risk patients, but trends in life expectancy have led to an increase of elderly but fit individuals with aortic stenosis eligible for TAVI. Methods: We reviewed the current evidence base on TAVI in the elderly by conducting an umbrella review (i.e., overview of systematic reviews), based on a formal bibliographic search for systematic reviews on TAVI in elderly patients (≥ 65 years). Key, study, patient, procedural, and outcome data were extracted, and validity formally appraised with the
