*6.1.4 Transcatheter aortic valve implantation (TAVI)*

TAVI was developed as an alternative to AVR in the very or extremely high-risk patient population, and its first implantation in man was performed by Cribier [42] in 2002. Since then, there has been a nonstop development of less invasive strategies with lower mortality, lower morbidity, and less invasiveness [43].
