Activity and outcomes for aortic valve implantations performed in England and Wales since the introduction of transcatheter aortic valve implantation

This study describes activity and outcomes for both standard aortic valve implantation and transcatheter aortic valve implantation (TAVI) in England and Wales in the TAVI era. The study demonstrates that both standard aortic valve implantation and TAVI acitivity have increased since TAVI was first performed in the United Kingdom. The proportion of all aortic valve implantations performed by TAVI has increased from 0.8% in 2007 to 10.9% in 2012. Procedural outcomes have improved for both standard AVR and TAVI over time.
