Transcatheter aortic valve implantation in patients with severe symptomatic aortic stenosis: position statement of the Italian Society of Interventional Cardiology (SICI-GISE) on minimum standards for hospitals and operators].

At present, transcatheter aortic valve implantation (TAVI) is a proven treatment option for patients with symptomatic degenerative aortic stenosis at high risk for conventional surgery. In countries where TAVI is currently performed, the number of procedures and centers involved has been continuously increasing. The present document from the Italian Society of Interventional Cardiology (SICI-GISE) aims to improve the available evidence and current consensus on this topic through the definition of training needs and knowledge base for both operators and centers.
