What Is LAA Closure?
In patients with AFib, an irregular heart rhythm, blood clots frequently form in a small pocket of the heart called the left atrial appendage. These clots can travel to the brain and cause a stroke. LAA Closure permanently seals off this pocket using a small device, addressing the stroke risk at its source.
How Is LAA Closure Done?
A catheter is guided from a vein, usually in the groin, into the heart
Using imaging guidance, the catheter reaches the left atrial appendage
A small closure device is deployed to seal the opening of the appendage
Over time, heart tissue grows over the device, permanently closing off the pocket
Who Needs LAA Closure?
AFib patients at risk of stroke who cannot safely tolerate long-term blood-thinning medication
Patients who have experienced bleeding complications on blood thinners
Patients seeking an alternative to lifelong daily medication
What Are the Risks of LAA Closure?
Bleeding or vascular access complications
Device-related blood clot formation
Device movement or improper positioning
Fluid around the heart (pericardial effusion), in rare cases
Frequently Asked Questions
Does LAA Closure replace the need for blood thinners immediately?
Most patients continue a short course of blood-thinning medication after the procedure while the device fully seals, transitioning off long-term therapy afterward, based on their doctor guidance.
Is LAA Closure a one-time procedure?
Yes —It’s a single procedure, unlike blood-thinning medication which must be taken daily, indefinitely.
