Conclusions

We have seen from large RCTs that short- and long-term outcomes of TAVR were similar or superior to those of surgery in TAV patients. Despite the absence of controlled studies comparing surgery with TAVR in BAV patients, there are several observational studies showing comparable outcomes of TAVR in BAV and TAV AS. However, we should avoid invalid syllogistic reasoning and conclude that TAVR is similar to SAVR in BAV AS patients. Many uncertainties remain in the indications of TAVR in the absence of RCTs or longer-term follow-up. Further trials are needed to define the anatomic features of BAV that are the most suitable for TAVR as well as the optimal sizing technique and best implantation techniques. Surgery remains the first-line treatment for the vast majority of BAV patients. Nevertheless, TAVR using the latest THV prostheses may be a safe and reasonable alternative in patients with increased risk for surgery after a meticulous imaging evaluation of the AV anatomy.
