Does circumferential PV isolation maintain stable sinus rhythm and prevent chronic AF in patients with paroxysmal AF and normal left ventricular function?
Circumferential PV isolation provides long-term maintenance of sinus rhythm and prevents progression to chronic AF in patients with paroxysmal AF and normal LV function.
In patients with paroxysmal AF and normal left ventricular function, circumferential PV isolation results in stable sinus rhythm in the majority of patients, and low incidence of chronic AF was observed after ablation during up to 5 years of follow-up.
