Key result
TAVI emerges as a rapidly evolving alternative to SAVR for high-risk severe symptomatic AS.
Why the study?
Surgical aortic valve replacement is the gold-standard for severe symptomatic aortic stenosis, but alternatives are needed for patients at high surgical risk.
This review provides an overview of the TAVI technique, patient selection criteria, and short- to medium-term outcomes for high-risk patients with severe symptomatic aortic stenosis.
Offers less invasive option for high-risk aortic stenosis; leaves open durability and broader applicability.
Aortic stenosis is the most commonly acquired valvular heart disease in the Western world. Surgical aortic valve replacement is currently the gold-standard treatment for patients with severe symptomatic aortic stenosis. Without surgery, the prognosis is extremely poor, with a 3-year survival rate of less than 30%. Transcatheter aortic valve implantation (TAVI) is a rapidly evolving novel technique that was first introduced in 2002 and is currently available in Europe as an alternative to conventional aortic valve replacement for patients with severe symptomatic aortic stenosis who are deemed to be at too high a risk for open heart surgery. This article describes the TAVI technique and patient selection criteria. We explore how far we have come with advances in TAVI and analyze the short- and medium-term outcome data reported on TAVI so far. We will also look at the potential future role of TAVI and the challenges involved in setting up a TAVI service.

Sambu et al. (2010) conducted a review in severe symptomatic aortic stenosis. Transcatheter aortic valve implantation (TAVI) vs. conventional aortic valve replacement was evaluated. Transcatheter aortic valve implantation is a rapidly evolving alternative to conventional aortic valve replacement for patients with severe symptomatic aortic stenosis at high surgical risk.
