Abstract
Following the first implantation of a percutaneous valve in 2002, two of the leading
manufacturers of biological valve prostheses developed percutaneous aortic
platforms, which have promoted transcatheter aortic valve implantation (TAVI) as
an alternative to surgical aortic valve replacement (SAVR). In the last decade, both
companies have funded six randomized studies grouping patients according to
surgical risk and comparing the results between the two therapies. None of these
studies has demonstrated the superiority of one technique over the other in terms
of 5-year mortality. In general, patients who received percutaneous valves suffered
a higher incidence of the need for pacemaker implantation, perivalvular leaks, and
vascular complications, while surgical patients suffered more bleeding and atrial
fibrillation. Following these results, the use of TAVI in young and low-risk patients has
exponentially increased.
