Does segmental pulmonary vein isolation provide clinical efficacy in patients with paroxysmal and persistent atrial fibrillation?
Patients with paroxysmal and persistent atrial fibrillation
Segmental pulmonary vein isolation targeting at least 3 pulmonary veins
Clinically satisfactory result / clinical efficacy
Segmental pulmonary vein isolation is highly effective for paroxysmal atrial fibrillation but has significantly lower efficacy for persistent atrial fibrillation.
With a segmental isolation approach that targets at least 3 PVs, a clinically satisfactory result can be achieved in >80% of patients with paroxysmal AF. The clinical efficacy of pulmonary vein isolation is much lower when AF is persistent than when it is paroxysmal.
