Description of intervention(s) / exposure
This study will examine the use of TAVR (Transcatheter Aortic Valve Replacement), which is a minimally invasive procedure designed to replace the aortic valve inside the heart. The JenaValve Pericardial TAVR System will be examined in this clinical study for aortic valve replacement. The TAVR procedure is performed by a heart surgeon and a cardiologist. The TAVR device may be implanted transapical, which is placed through your chest wall, or transfemoral, which is placed though an artery in your groin. The choice of which which approach is used is at the clinical discretion of the study physicians.. The TAVR procedure typically takes 1-2 hours to complete. The JenaValve TAVR device, once implanted, is designed to remain permanently in place.

Statistical methods / analysis
This study is a single-arm, multi-center, prospective feasibility study that is exploratory in nature. It is anticipated that a maximum of 30 mITT (modified intention to treat) subjects will be included to initially assess the safety and feasibility of the procedure and investigational device.
Continuous outcome variables will be presented as means and standard deviations, as well as medians and ranges. For categorical outcome variables, relative frequencies will be provided. Descriptive tables will be produced for baseline characteristics.

Summary
Brief summary
The purpose of this research study is to collect information about a new treatment for severe aortic stenosis, which affects the aortic valve in the heart. Aortic stenosis is a narrowing of the aortic valve opening, which decreases blood flow from the heart and causes symptoms such as chest pain, fainting and shortness of breath. The preferred treatment for severe aortic stenosis is aortic valve replacement surgery. A less invasive surgical approach called TAVR (also known as TAVI) is offered to those patients who are high risk for undergoing open heart surgery to replace the aortic valve. In this study, TAVR will be performed using the JenaValve Pericardial TAVR System, which is intended to help treat severe aortic stenosis. The JenaValve replacement valve is placed inside the aortic valve by using the JenaValve delivery system. The JenaValve replacement valve may be implanted in one of two ways: (1) transapical - where the valve is implanted through the chest wall, and (2) transfemoral – where the valve is implanted through an artery in the groin. The choice of which implant method will be used is decided by the doctor.
