About
The ablation of atrial fibrillation (FA) by disconnection of pulmonary veins is a burgeoning intervention. It allows a long-term treatment of this arrhythmia with a success rate of about 80%. There are, nevertheless, some recidivism.
Risk factors for recidivism are poorly codified and need further research. Indeed the identification of factors of poor prognosis could lead to not propose this procedure to the patients who present them and at least to inform them of an increased risk of failure.
To date, aortic stiffness has not been studied in the context of assessing the risk factors for FA recurrence after ablation. On a physiopathological level, the aortic stiffness leads to increase left ventricle's post-load. Cardiac remodeling was observed with diastolic dysfunction and increased left atrial size. That may constitute a substrate for FA recurrence.
In the literature, aortic stiffness can be measured in several ways:
The investigators propose to evaluate the impact of aortic stiffness on the recidivism of FA 6 months after ablation procedure performed in the Croix-Rousse cardiology's department.
