DEFLECT I: Keystone Heart Embolic Deflection Trial

Status Completed

Clinical Trial Summary

Clinical Trial Description

This is a research study using the Keystone Heart Embolic Deflection Device and involving patients with aortic stenosis (a disease of the aortic valve), to be treated with Transcatheter Aortic Valve Replacement (TAVR).

The TAVR procedure consists in replacing the diseased aortic valve by a new artificial valve. The new valve is put into place using a long, thin tube called a catheter that is inserted into a small incision (cut) in the patient's groin and threaded through his/her arteries up to the heart.

During the TAVR procedure, there is a risk that an abnormal particle (called embolism) could break off from inside the arteries and travel to the brain. The embolism could be made of clumps of blood (clots), air, part of your body tissue, or part of a medical device. If the embolism is carried through the blood to the brain, it could cause a stroke or other neurological (brain) problems. A stroke happens when blood flow to a part of the brain is blocked, causing brain cells to die.

The Keystone Heart Embolic Deflection Device has been developed to prevent an embolism from going to the brain and causing a stroke or other brain damage. The device is a wire mesh filter that covers the vessels that carry blood to brain, deflecting any any blood clots or other materials away from the patient's brain and towards the lower body, where they are less likely to cause harm. ;
