While in young patients pulmonary vein isolation (PVI) has evolved as first option, in older patients decision is often made in favor of drugs as higher complication rates and less benefit are suspected. Therefore, data on PVI of paroxysmal and persistent AF in these patients is still sparse but of eminent importance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Hypothesis<\/jats:title><jats:p>PVI is comparably safe in the very elderly with similar recurrence and complication rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We enrolled all patients (n = 146) aged &gt;75\u2009years who underwent a first PVI over a period of 10\u2009years (2009\u20102019) from our prospective single\u2010center ablation registry. Mean follow\u2010up time was 231\u2009\u00b1\u2009399\u2009days.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Acute ablation success defined as complete PVI and sinus rhythm at the end of the ablation procedure was high (99%). Severe periprocedural complications occurred in 3.3% (stroke\/TIA n = 2; 1.3%; pericardial effusion n = 3; 2%). In 4.6% of patients symptomatic sick\u2010sinus\u2010syndrome was unmasked after PVI resulting in pacemaker implantation. There were no deaths related to PVI. Recurrence rate of symptomatic AF was 37.3% resulting in a Re\u2010PVI and\/or substrate ablation in 32 pts (20.9%). During follow\u2010up pacemaker implantation plus atrioventricular node ablation was performed in 10 pts (6.8%). There was a trend toward lower recurrence rates with single\u2010shot devices (cryoballoon, multielectrode phased\u2010radiofrequency ablation catheter) than with point\u2010by\u2010point radiofrequency while complication rates did not differ.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>PVI for AF is a feasible treatment option also in patients &gt;75\u2009years with a reasonable success and safety profile.
