Minimally invasive surgery for atrial fibrillation.

Area of Science:

• Cardiac Surgery
• Electrophysiology
• Arrhythmia Management

Background:

• Atrial fibrillation (AF) is the most common cardiac arrhythmia, affecting 2% of the global population.
• Minimally invasive surgical ablation is a rapidly advancing field in cardiac surgery.
• Current evidence gaps exist for catheter-based ablation in persistent AF, creating opportunities for surgical interventions.

Purpose of the Study:

• To present two distinct minimally invasive surgical ablation approaches for atrial fibrillation.
• To highlight the importance of patient selection and a Heart Team approach.
• To discuss the Standalone surgical isolation and the Convergent Procedure.

Main Methods:

• Review of the Standalone surgical isolation of pulmonary veins using bipolar energy, including left atrial appendage amputation (FAST Trial methodology).
• Description of the Convergent Procedure, combining minimally invasive endoscopic surgery with electroanatomical mapping for endocardial and epicardial ablation.
• Emphasis on a multidisciplinary Heart Team approach for tailored treatment strategies.

Main Results:

• The review contrasts a purely surgical approach with a combined surgical-electrophysiological strategy.
• The Convergent Procedure integrates minimally invasive surgery and electrophysiology for comprehensive ablation.
• The Heart Team approach aims to optimize patient selection and resource utilization.

Conclusions:

• Minimally invasive surgical ablation offers viable alternatives, particularly for persistent AF.
• The Convergent Procedure represents a complex, multidisciplinary approach combining surgical and catheter-based techniques.
• Tailored treatment strategies and collaborative care are crucial for improving outcomes and patient satisfaction in AF management.
