Left atrial appendage occlusion devices
It is an advanced catheter-based procedure that can be an important
alternative for patients affected by atrial fibrillation.
The procedure is the left atrial appendage closure with the device. The procedure involves
the placement of the device in the heart to prevent blood clots from entering the
bloodstream, reducing the risk of stroke.
A Fib is a condition in which the upper chambers of the heart beat too quickly in an irregular
rhythm. This can cause blood to pool and form clots in the left atrial appendage (LAA), a
small sac in the lining of the upper left heart chamber. Blood clots can make their way from
the LAA into the bloodstream and cause a stroke.
Device implant works by closing off the LAA and lowering the chance of blood clots entering
The device is implanted using a special catheter containing the LAA device
and inserted into a large blood vessel in the groin. Using advanced imaging
techniques and equipment, the catheter is gently moved through blood
vessels to the left atrium of the heart. The catheter is positioned in the LAA,
where the implant is released so it closes the appendage off from the left
atrium. Over time, the body's own tissue grows over the surface of the
