New Treatment Option Cuts Stroke Risk for Irregular Heart Rhythm Patients
The MetroHealth System is first in Northeast Ohio to perform procedure
Cardiologists at The MetroHealth System were the first in Northeast Ohio to perform the Lariat procedure - a new way for physicians to help patients with atrial fibrillation (AFib) minimize their stroke risk. The non-surgical procedure was performed on April 9th.
A patient with AFib may have blood pooled in the left atrial appendage of the heart’s top chamber, which can cause blood clots and lead to stroke. Previously, if a patient was unable to take blood thinning medications to reduce this stroke risk, they would have to undergo open heart surgery to tie off the appendage to lessen the risk.
“Using the Lariat® Suture Delivery Device, we perform a minimally invasive procedure to tie off the appendage,” said Ohad Ziv, MD, Director of the Atrial Fibrillation Center at MetroHealth. “For people with no other options, this is the solution for potentially saving lives.”
A cardiac electrophysiologist guides two catheters entering the body through one small incision in the groin and one just under the rib cage. From each catheter, a wire is advanced to the left atrial appendage, one from the inside of the heart and the other from the outside of heart. These wires have with tiny magnets at the ends. When the magnets connect, a specialized catheter called the Lariat® Suture Delivery Device can be advanced over the left atrial appendage.
After the wires are pulled back, a suture is deployed from the Lariat around the left atrial appendage to tie it off. With the left atrial appendage closed, blood cannot enter, and blood clots cannot form, reducing the risk of stroke associated with atrial fibrillation.
“The recovery time for this procedure is much less than for open heart surgery,” said Dr. Ziv. “It’s a safe alternative for people who cannot be on blood thinners due to fall risk or bleeding, but at the same time face a high risk of stroke due to their atrial fibrillation.”
Atrial fibrillation affects more than 2 million Americans. It is a condition characterized by irregular heartbeat and can lead to high risk of heart failure and stroke.
MetroHealth cardiologists Ohad Ziv, MD, Grace Cater MD, and Sanjay Gandhi, MD and Michael Cutler MD assisted on the procedure.
The Lariat® Suture Delivery Device is manufactured by SentreHEART, Inc. in Redwood City, CA.
