- Brief Summary
Therapeutic management of Atrial Fibrillation (AF) is based either on heart rate control or on rhythm control, a strategy which aims to maintain a normal heart rhythm. The benefit in terms of morbidity and mortality of a normal heart rhythm would, however, be largely offset by the frequent side effects of antiarrhythmic drugs which could even lead to an increase in mortality compared to rate control. This increase has particularly been suggested in people aged over 75.
Since the emergence of catheter Pulmonary Vein Isolation (PVI), an effective alternative to antiarrhythmic drugs has become available. This technique makes it possible to isolate the foci triggering AF under local or general anesthesia with greater effectiveness than medications and very low risks. Records in the elderly do not seem to show a reduction in effectiveness or an increase in complications. However, in the absence of a dedicated randomized study, its use is strongly limited in the elderly where rate control (52% of people over 65 years old) and the use of antiarrhythmic drugs are largely favored due to the simplicity of implementation and the low cost of medications.
However, an early rhythm control strategy seems to reduce cardiovascular events in relatively old individuals (average age 70 years). The use of PVI in first line could make it possible to further improve these results.
The objective of the investigator is therefore to carry out the first randomized comparative study proposing to evaluate the impact of early PVI compared to usual treatment in patients aged 75 and over with AF.
