[Left atrial appendage occlusion in elderly].

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• Non-valvular atrial fibrillation (NVAF) poses significant stroke and bleeding risks.
• Oral anticoagulation therapy (e.g., VKA) is standard but carries bleeding risks and contraindications.
• Elderly patients (>75 years) have elevated risks and often suboptimal anticoagulation.
• Left atrial appendage occlusion (LAAO) is an alternative to oral anticoagulation for NVAF.

Purpose of the Study:

• To evaluate the efficacy and safety of LAAO in elderly patients with NVAF.
• To assess LAAO as a viable alternative for patients with contraindications to oral anticoagulation.
• To determine if LAAO offers benefits comparable to or exceeding anticoagulation in this high-risk group.

Main Methods:

• Review of published studies on LAAO procedures in elderly NVAF patients.
• Analysis of peri-procedural complication rates, including tamponade.
• Comparison of long-term safety and efficacy with younger patient cohorts and anticoagulation therapy.

Main Results:

• LAAO procedures demonstrate excellent feasibility and efficiency in elderly patients.
• While peri-procedural complications may be slightly higher, long-term safety is comparable to younger patients.
• LAAO reduces ischemic stroke risk compared to no treatment and bleeding events compared to VKA therapy.

Conclusions:

• Interventional percutaneous LAAO is an attractive and effective strategy for elderly patients with atrial fibrillation.
• LAAO should be considered within a multidisciplinary management approach for this population.
• The procedure offers a favorable risk-benefit profile for elderly NVAF patients, especially those with contraindications to anticoagulation.
