72-year-old male had a TIA in 1995 and has been in chronic atrial fibrillation since 1992. In 2005 2 ablative procedures were ineffective. The main treatment strategy for his atrial fibrillation has consisted of rate control and oral anticoagulation. Despite several attempts of different medications (digoxin, beta-blockers) he has remained in atrial fibrillation with a relatively moderate to fast ventricular response.

p68-year-old male with recurrent asymptomatic paroxysmal atrial fibrillation underwent ablation of the cavo-tricuspidal isthmus. Holter exams showed sinus rhythm with brief and isolated episodes of atrial fibrillation, again with focal trigger. The choices of therapy are rate control, rhythm control, catheter ablation or antithrombotic therapy.
