You have a condition known as atrial fibrillation where the upper chambers of your heart (atria) are beating too fast and quivering (fibrillation). An effect of this condition is blood pooling and forming clots in an area of your heart called the left atrial appendage (LAA). If these clots leave the LAA, they can travel to your brain and cause a stroke.

As an option for AFib patients who cannot tolerate other medical therapy, your physician has recommended LAA closure with the LARIAT to reduce the risk of a clot forming or leaving the LAA. The LARIAT procedure is a minimally invasive approach that will immediately and permanently close the LAA and prevent blood clots entering the blood stream.


The LARIAT closes the LAA by remotely delivering a pre-tied suture loop precisely to the base of the LAA for immediate and complete closure. The procedure is performed using non-invasive imaging, including fluoroscopy (x-ray) and ultrasound referred to as trans-esophageal echocardiography.

Unlike other LAA closure devices, the LARIAT leaves nothing on the inside of the heart. Within a few months after closure with the LARIAT, the LAA will disappear and never again be a source of blood clots.



1. During the procedure, you will be under anesthesia or sedation. Using x-ray guidance, two small catheters will be positioned at the LAA. One will be on the inside and the other on the outside to ensure ideal placement of the LARIAT suture.


2. Using small guide wires that are connected with magnets, the LARIAT will be advanced to the base of the LAA from the outside. Once in position, your doctor will close the LARIAT and release the suture that will tighten and close off the LAA.


3. After closure of the LAA, the LARIAT and the guide wires will be removed, leaving nothing behind inside of your heart. Only a small piece of suture will remain at the base of the LAA on the outside. Closure will be immediate and complete at the end of the procedure.

Post Procedure

4. Over time, the LAA will shrink away and disappear due to the closure eliminating blood flow to the LAA. As a result, the LAA will no longer ever be a risk as a source of blood clots.


Over 6,800 LARIAT procedures have been performed worldwide. The LARIAT received CE Mark certification in Europe and was FDA-cleared in the United States for soft-tissue closure in 2009.

I can dance and enjoy life. The procedure changed everything.

I did not want to be a slave to a pill. I would recommend the LARIAT procedure to anyone who has Afib.

I feel wonderful. I have been given a new life and I would recommend it [LARIAT] to anyone with this problem.

A golden opportunity for me and my health. It is a great feeling.

I feel healthy. I am really happy.
