The ARTEMIS Data Collection Study

To observe the safety and effectiveness of the JenaValve Trilogy™ Heart Valve System for transcatheter aortic valve replacement (TAVR) in subjects with evere native aortic regurgitation (AR) who are indicated for TAVR Data collection

To observe the safety and effectiveness of the JenaValve Trilogy™ Heart Valve System for transcatheter aortic valve replacement (TAVR) in subjects with evere native aortic regurgitation (AR) who are indicated for TAVR Data collection . A retrospective/prospective, single-arm, post-market study to monitor the outcomes of Jena Valve Trilogy in a real-world clinical setting . After enrollment is completed, patients are followed to 1 year (an amendment to extend the follow up to 5 years will be evaluated). Thereafter, the patient exits the data collection study and is to be followed per institutional standard of care for TAVR patients. The JenaValve Trilogy™ Heart Valve System contains the following sub-components: a prosthetic transcatheter porcine pericardial aortic valve, 20Fr Introducer Sheath System, transfemoral Delivery Catheter, and Loading Tool. Indications for Use: The JenaValve Trilogy™ Heart Valve System is indicated for use in patients with clinically significant aortic regurgitation (AR) who are considered high risk candidates for surgical aortic valve replacement as deemed by the local multi-disciplinary heart team. This is an investigator initiated study that will include 75 suitable patients according to the inclusion/exclusion criteria as per IFU.
