New Procedure Offers Alternative to Blood Thinners for AFib Patients
A new, minimally invasive heart procedure will soon be available at Midland Memorial Hospital, offering an important option for patients living with atrial fibrillation (AFib), a common heart rhythm disorder that significantly increases the risk of stroke.
AFib affects millions of Americans and becomes more common with age. Because the heart does not beat in a regular rhythm, blood can pool and form clots—particularly in a small pouch of the heart called the left atrial appendage. If a clot travels to the brain, it can cause a stroke.
For years, the primary way to reduce this risk has been blood-thinning medications. While highly effective, these medications can increase the risk of bleeding and may not be suitable for everyone. Some patients experience serious bleeding complications, while others face challenges taking these medications long term.
The procedure, called left atrial appendage occlusion (LAAO), provides another approach.
Rather than relying on medication, LAAO works by sealing off the part of the heart where most stroke-causing clots form. The procedure is performed in a cardiac catheterization lab using a minimally invasive approach. Physicians guide a small device through a vein in the leg to the heart and cross from the right to the left side of the heart through a technique called transeptal access. The device is then positioned to close off the left atrial appendage. Over time, the body’s own tissue grows over the device, permanently sealing it.
Most patients go home the next day and return to normal activities within a few days. After the procedure, patients typically need to continue take a blood thinner or a combination of antiplatelet medications for 6 months while the device heals into place.
Recent clinical studies have shown that LAAO provides similar protection against stroke as blood-thinning medications, while offering the important advantage of reducing the risk of long-term bleeding complications in appropriate patients.
Bringing this procedure to Midland Memorial Hospital will allow more patients in our community to receive this advanced care closer to home, rather than traveling to other cities for treatment. For many patients and families, avoiding long trips for specialized procedures means less disruption, easier coordination of care, and better access to follow-up visits.
Offering LAAO locally also strengthens the ability to provide comprehensive heart care within our region. Patients can be evaluated, treated, and monitored by a consistent care team, improving continuity and communication. This can be especially valuable for older adults or those with multiple medical conditions who benefit from coordinated, close-to-home care.
As with any medical procedure, LAAO is not appropriate for everyone. Patients with atrial fibrillation who have questions about stroke prevention or concerns about blood thinners are encouraged to speak with their physician to learn whether this option may be right for them.
