Surgical Ablation for Atrial Fibrillation

May 19, 2020 updated by: Hong Liu, Nanjing Medical University

Minimally Invasive Surgical Ablation for Standalone Atrial Fibrillation

Minimally invasive approaches for surgical treatment have been advocated as a treatment option for stand-alone atrial fibrillation (AF). This study will investigate the clinical outcomes after minimally invasive surgical ablation of both paroxysmal and persistent/longstanding persistent AF.

Detailed Description

Atrial fibrillation (AF) patients with a previous stroke are often at a high risk of recurrent stroke and bleeding. Minimally invasive approaches for surgical treatment have been advocated as a treatment option for stand-alone AF. This study will investigate the clinical outcomes after minimally invasive surgical ablation of both paroxysmal and persistent/longstanding persistent AF. Neurological safety will be assessed by cerebral magnetic resonance, neuropsychological examination and periprocedural transcranial Doppler measurement.

Study Population

patients with symptomatic, drug-resistant, stand-alone, paroxysmal, persistent or long-standing persistent atrial fibrillation

Description

Inclusion Criteria:

  • Patients age > 18 years
  • Patients with paroxysmal, or persistent/long-standing persistent AF according to the standard EHRA definition.
  • Patients with symptomatic AF that is refractory to at least one antiarrhythmic medication.
  • Absence of significant structural heart disease (dilated cardiomyopathy, hypertrophic cardiomyopathy, valvular heart disease, untreated coronary artery disease)

Exclusion Criteria:

  • AF secondary to a reversible cause (i.e., thyreopathy, etc.) Indication for open-heart surgery (coronary artery bypass grafting, valve surgery, etc.)
  • Severe left ventricle dysfunction that is clearly caused by some other cardiac disease (dilated cardiomyopathy, ischaemic heart disease, etc.) where the AF is clearly of secondary etiology
  • Known severe pericardial and pleural adhesions (e.g., history of cardiac surgery)
