Aortic Stenosis: Balloon-Expandable Bioprosthetic SAPIEN X4 Transcatheter Heart Valve

What is the Purpose of this Study?

The purpose of this study is to determine whether an investigational device called the Sapien X4 Transcatheter Heart Valve system is beneficial for patients with symptomatic, severe, calcific aortic stenosis. Aortic stenosis is a condition in which the opening of the heart valve becomes smaller, making it more difficult for the heart to pump blood. In this study, participants will have their valve replaced by the Sapien X4 Transcatheter Heart Valve system, which includes an artificial heart valve and accessories used to implant the valve. Each valve consists of a stent (metal mesh tube) made of a metal frame with knitted fabric covering some of the frame. The SAPIEN X4 delivery system consists of a catheter (a long, thin, bendable tube that is placed in a blood vessel) that is inserted through an incision made in the groin and moved through blood vessels to the heart.
