Journal of cardiothoracic surgery·2026

This study on surgical ablation for atrial fibrillation found that assessing sinus nodal function and using mitral annular incisions during pulmonary vein isolation effectively restored sinus rhythm in 92% of patients.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Electrophysiology

Context:

  • Atrial fibrillation (AF) is a common arrhythmia requiring effective treatment.
  • Surgical ablation, including pulmonary vein isolation (PVI), is a key therapeutic strategy.
  • Chronic and paroxysmal AF present distinct challenges for rhythm restoration.

Purpose:

  • To evaluate the efficacy of a specific surgical technique for PVI in patients with AF.
  • To identify critical intraoperative factors influencing the success of rhythm restoration.
  • To assess the role of sinus nodal function and mitral annular extension in surgical AF ablation.

Summary:

  • A review of a surgical PVI series for chronic and paroxysmal AF was conducted.
  • Intraoperative assessment of sinus nodal function and the addition of a mitral annular incision to PVI were identified as crucial for restoring sinus rhythm.

  • A significant success rate of 92% in restoring sinus rhythm was observed in patients with good sinus nodal function.

    • Impact:

    • Findings provide valuable insights for optimizing surgical ablation strategies for AF.
    • The study highlights the importance of intraoperative electrophysiological assessment and procedural modifications.
    • Results are relevant for both traditional surgical ablation and approaches incorporating new energy sources.
