Full description
Catheter ablation is an established standard therapy in interventional treatment of atrial fibrillation. electric isolation of the pulmonary veins, from which atrial fibrillation is originating in most patients, is cornerstone of all atrial fibrillation patients.
The most common cause for AF recurrence is still incomplete isolation of the pulmonary veins, on the other hand, only 80% of paroxysmal and 60 % of persistent patients can successfully be cured from atrial fibrillation (despite of isolated pulmonary veins after multiple ablation procedures).
By now, non-procedure related predictive risk factors, resulting in recurrence of atrial fibrillation after catheter ablation, are only partially identified, such as obesity, hypertension and sleep apnea.
In the past year several genetic risk alleles were identified, which are associated with atrial fibrillation. By now the relation between genetic risk, which is determined for every patient by its specific genotype and the outcome of catheter ablation in paroxysmal and persistent atrial fibrillation has not yet been investigated.
The aim is to investigate the influence of genetic risk for the recurrence of atrial fibrillation after catheter ablation.
