Full Study Name

Evaluation of the Portico NG Transcatheter Aortic Valve in High and Extreme-Risk Patients With Symptomatic Severe Aortic Stenosis (ABT-CIP-10297) (IRB no. 00000152)


This study focuses on individuals with a heart valve condition (aortic stenosis) who are at high or extreme risk for open-heart surgery. The purpose of the study is to evaluate an investigational device called the Portico NG transcatheter aortic valve implantation (TAVI) system, which is used to treat aortic stenosis.

The Portico NG transcatheter heart valve can be placed into the diseased heart valve without the need for open heart surgery. The valve is attached to a stent, or scaffold, which holds the valve in position. The Portico NG valve is used in combination with the FlexNav delivery system, which can maneuver through narrow blood vessels and improve the ability to position the Portico NG valve in place. Researchers aim to collect data on the Portico NG valve and FlexNav delivery system, as well as support commercial approval of the device.
