<h4 class="h4">Objectiveh4>To evaluate the clinical indications and guidelines for transcatheter aortic valve implantation (TAVI) and to propose adaptations for its use in Portugal.<h4 class="h4">Methods and Resultsh4>

The working group analyzed the epidemiology of aortic stenosis and current clinical recommendations in the light of current evidence, taking into consideration their own experience in Portugal.

The evidence shows that TAVI significantly reduces mortality in patients with severe aortic stenosis considered unsuitable for surgery. This technique has a comparable safety profile, efficacy and quality of life improvement to conventional surgery in patients with high surgical risk, when carefully selected by multidisciplinary teams.

TAVI procedures should be performed within multidisciplinary programs in centers with on-site cardiac surgery by experienced teams treating no fewer than 50 cases per year in order to maintain proficiency.

The technique is little used in Portugal, with seven implantations/year per million population, a seventh of the European average and the lowest rate in Europe.

From a societal standpoint, it is important to evaluate clinical outcomes and analyze the incremental cost involved in order to define the situations in which the technique is appropriate and should be used.<h4 class="h4">Conclusionh4>

TAVI is the only treatment for severe aortic stenosis in patients unsuitable for surgery, and can also be applied in selected cases with high surgical risk.

Patients who are considered for this treatment should be evaluated in centers of excellence performing the technique and with a formal program of multidisciplinary team work. The first cases should be supervised until the team has established its routine. The program should perform the recommended minimum number of procedures per year in order to maintain proficiency and must keep a prospective clinical registry for monitoring purposes.
