Portico NG Approval Study

Symptomatic Severe Aortic Stenosis Clinical Trial

Official title: Evaluation of the Portico™ NG (Next Generation) Transcatheter Aortic Valve in High and Extreme Risk Patients With Symptomatic Severe Aortic Stenosis

Status Active, not recruiting

Clinical Trial Summary

The purpose of this clinical study is to evaluate the acute safety and effectiveness of the next-generation Navitor (Portico™ NG) Transcatheter Aortic Heart Valve as assessed by the rate of all-cause mortality at 30 days and the rate of moderate or greater paravalvular leak at 30 days in a high or extreme surgical risk patient population to support CE (Conformité Européenne) Mark and FDA approval.

Clinical Trial Description

The Portico NG Approval study will be conducted as a prospective, multi-center, international, single-arm investigational study.

Up to 399 (includes up to 20 roll-ins) high or extreme risk patients with symptomatic, severe native aortic stenosis who are determined by an independent subject selection committee to meet eligibility criteria for Navitor Transcatheter Aortic Heart Valve implantation will undergo Navitor Valve implantation via a transfemoral or alternative access approach according to the site's anesthesia protocol for TAVR (transcatheter aortic valve replacement) procedure.

Subjects participating in the clinical study will be followed for a total of 12 months with data collected at screening, baseline, procedure, prior to hospital discharge, and follow-up at 30 days, 12 months and annually at 2, 3, 4 and 5 years.

This study will also include a product size extension, Navitor Titan™ valve, which includes up to 90 subjects (Titan cohort) who will undergo an implant attempt with the Navitor Titan valve. Subjects enrolled in the Titan cohort will undergo the same screening, baseline, procedure and follow-up assessments as the Portico NG cohort. ;
