The Portico transcatheter aortic valve for the treatment of severe aortic stenosis

The Portico TAVI system (Abbott Vascular, Santa Clara, CA, USA) has been specifically designed to mitigate some of the complications associated with first-generation valves. Most of the data generated from randomized studies comparing transcatheter aortic valve implantation with surgery stem from reported experiences with first generation transcatheter heart valve devices. The aim of this review is to describe the repositionable and retrievable Portico system and its implantation technique, coupled with our single-center experience and to provide a review of the clinical results reported so far in the literature.
