Methods:
From October 2014 to July 2018 a total of 1548 patients were referred in
our center for first time and/or redo interventional treatment of
medically refractory recurrent paroxysmal and persistent AF. Seventy-one
of those patients (Age: 61 ± 12 years, males: 47) developed recurrent AF
after index RF-PVI and underwent a second procedure in our center. A
3D-RA was performed before index and redo procedure for the subset of
patients in the presented analysis. This study was reviewed and approved
by our institutional ethics committee and all patients granted their
written consent to participate.
