Atrial fibrillation (AF) management involves anticoagulation for embolism risk and interventional procedures like ablation for uncontrolled rapid rhythms. Pulmonary vein isolation can treat paroxysmal AF but carries risks.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Interventions

Background:

  • Atrial fibrillation (AF) is a common arrhythmia with variable symptoms.
  • Patients with AF and embolism risk require anticoagulation.
  • Rapid ventricular response in AF may necessitate interventional treatment.

Purpose of the Study:

  • To review therapeutic approaches for atrial fibrillation.
  • To discuss interventional strategies for managing AF symptoms and complications.

Main Methods:

  • Radiofrequency catheter ablation of the atrioventricular junction with pacemaker implantation.
  • Catheter ablation for pulmonary vein electrical isolation.

Main Results:

  • AV junction ablation with pacing effectively manages rapid rhythms and improves cardiac function in specific patient groups.

  • Pulmonary vein isolation can eliminate paroxysmal AF but may lead to complications like stenosis or embolism.

    • Conclusions:

    • AV junction ablation is suitable for older patients or those with severe left ventricular dysfunction.
    • Pulmonary vein ablation offers a treatment for drug-refractory paroxysmal AF but requires careful consideration of risks.
