¿Son iguales todas las prótesis? ¿Prótesis diferentes para indicaciones diferentes?

Transcatheter aortic valve implantation has become an accepted treatment option for patients with severe symptomatic aortic stenosis who are at a high surgical risk. In particular, randomized trials have shown that the technique is associated with lower mortality in inoperable patients than medical treatment and is noninferior to conventional surgery in patients at a high surgical risk. From its inception, transcatheter aortic valve implantation has shown great potential and, consequently, considerable effort has been devoted to designing new devices that can provide better outcomes and that can expand indications to ever more complex anatomies and to patients with multiple comorbidities. This review describes developments in the design of novel transcatheter prostheses and discusses recent findings with the application of these new-generation prostheses.
