Brief summary
The purpose of this clinical investigation is to characterize the procedural safety and device performance of transfemoral implantation of the Portico™ Transcatheter Aortic Heart Valve in patients with symptomatic degenerative aortic stenosis.
Detailed description
The CONFIDENCE registry study will be conducting as a prospective, non-randomized, observational, single-arm, multi-center study. Approximately 1000 subjects with severe symptomatic (NYHA class ≥ II) aortic stenosis (AS), will undergo Portico™ Transcatheter Aortic Heart Valve implantation. The subject data will be collected at baseline, index procedure, pre- discharge, 30 days and 12 months from the index procedure.
Interventions
Subjects will undergo implantation of a commercially available Portico transcatheter aortic heart valve using the Portico TAVI system.
Subjects will undergo implantation of a commercially available Portico transcatheter aortic heart valve using the FlexNav Delivery and Loading Systems.

Study design
Intervention model description
This registry will include market released Portico™ valves (23mm, 25mm, 27mm and 29mm), delivery systems and loading systems. The registry will also allow future iterations of the Portico valve and delivery system along with expanded indications to be included as they receive approval for commercial use in the country where the subject is enrolled.

Subjects who have been informed of the nature of the study, agree to its provisions and have provided written informed consent as approved by the Ethics Committee (EC) of the respective clinical center
Exclusion criteria
1. Have sepsis, including active endocarditis 2. Have any evidence of left ventricular or atrial thrombus 3. Have vascular conditions (i.e. caliber, stenosis, tortuosity, or severe calcification) that make insertion and endovascular access to the aortic valve improbable 4.

Class III: Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, shortness of breath or chest pain. Class IV: Symptoms of heart failure at rest. Any physical activity causes further discomfort.

Results are presented as percentage of all available subjects who were assigned each functional class (I-IV). |

NYHA Classification
NYHA Functional Classification is a system used to assess patient heart failure severity based on their limitations of physical activity. The four classes are described below: Class I: No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, or shortness of breath. Class II: Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, shortness of breath or chest pain. Class III: Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, shortness of breath or chest pain. Class IV: Symptoms of heart failure at rest. Any physical activity causes further discomfort. Subjects' NYHA Classification based on above criteria was assessed during follow up, and subjects were assigned to one of four classifications. Results are presented as percentage of all available subjects who were assigned each functional class (I-IV).
