Left Atrial Appendage Closure (LAAC) is a catheter-based procedure used for selected patients with atrial fibrillation (AF) who have a risk of stroke and may have difficulty with long-term anticoagulant treatment. The procedure seals the left atrial appendage, a small pouch where blood clots can form in some patients with AF.
Dr. Manish Juneja is an Interventional Cardiologist in Nagpur with experience in advanced cardiac interventions and device-based treatments.
What is Left Atrial Appendage Closure?
The left atrial appendage (LAA) is a small pouch attached to the left atrium. In certain patients with atrial fibrillation, blood can collect inside this pouch and increase the possibility of clot formation.
During LAAC, a closure device is delivered through a catheter and placed inside the appendage to seal it. The procedure is performed with cardiac imaging to guide device placement.
Who May Be Considered for LAA Closure?
LAA closure may be considered in selected patients with atrial fibrillation who have:
- Increased risk of stroke
- Concerns or complications related to long-term blood thinners
- A suitable LAA shape and size for device closure
- A medical reason to consider an alternative to long-term anticoagulation
A detailed cardiac assessment is required before deciding on the procedure.
How is the Procedure Performed?
A thin catheter is introduced through a blood vessel and guided toward the heart. The closure device is positioned inside the left atrial appendage and checked using appropriate imaging before release. After the procedure, the patient is monitored and receives follow-up care as advised.
Benefits of LAA Closure
- Minimally invasive catheter-based treatment
- Seals the left atrial appendage
- May help reduce clot-related stroke risk in selected patients
- Provides an option for some patients who cannot continue long-term anticoagulation
- Allows ongoing monitoring through follow-up evaluations
Precautions Before Left Atrial Appendage Closure
Complete Cardiac Evaluation
Undergo the imaging, blood tests, and other investigations recommended by your cardiologist.
Share Your Medical History
Inform your doctor about allergies, previous procedures, medical conditions, and current medicines.
Discuss Blood Thinners
Follow specific instructions regarding anticoagulant and antiplatelet medicines.
Report Recent Health Changes
Inform your medical team about fever, infection, or any new symptoms.
Follow Fasting Instructions
Follow the hospital’s instructions about food and fluids before the procedure.
Keep Previous Reports Ready
Carry relevant ECGs, echocardiograms, prescriptions, and other cardiac records.
Precautions After Left Atrial Appendage Closure
After Left Atrial Appendage Closure, take prescribed medicines regularly and avoid changing them without your cardiologist’s advice. Monitor the catheter-access site for bleeding, swelling, or unusual discomfort. Avoid heavy lifting and strenuous activities until medically permitted. Report chest pain, breathlessness, dizziness, fainting, or unusual weakness promptly. Attend all scheduled follow-up visits and recommended imaging to assess the closure device. Continue following your cardiologist’s advice regarding medicines, diet, physical activity, and long-term heart care.
