Objective:

To explain the benefits of the totally thoracoscopic (TT) maze surgery for treating longstanding persistent atrial fibrillation (AFib).

Approach:

• Surgical Technique: The TT maze procedure involves making small incisions between the ribs to access the heart, allowing for epicardial ablation without the need for open-heart surgery.
• Hybrid Approach: Combines epicardial ablation with endocardial ablation to improve outcomes for patients with longstanding persistent AFib.

Key Findings:

• Endocardial ablation is less effective for longstanding persistent AFib compared to paroxysmal AFib.
• The TT maze method provides a less invasive option with shorter recovery times.
• Patients experience minimal pain and can often go home after two nights in the hospital.

Interpretation:

The TT maze surgery offers a promising alternative for patients suffering from longstanding persistent AFib, potentially improving their quality of life.

Limitations:

• The procedure is technically challenging and not widely performed.
• Not suitable for all patients, particularly those with paroxysmal AFib.

Conclusion:

TT maze surgery represents a significant advancement in the treatment of longstanding persistent AFib, providing a minimally invasive option that can lead to improved patient outcomes.
