Condition: Valve Disease / Aortic Valve Disease
Investigator: Torsten Vahl, MD
Status: Currently Recruiting
The objective of the study is to evaluate the safety and efficacy of the JenaValve Pericardial TAVR system when treating patients with aortic regurgitation. Aortic Regurgitation is a condition that develops when the heart's aortic valve does close tightly, therefore the blood leaks back into the heart chamber. The JenaValve Pericardial TAVR system will…
