We included 25 consecutive patients who underwent endo-/epicardial AF CA
since September 2019 until February 2020.
The characteristics of the patients at baseline are presented in table
1. The most common indication for CA was longstanding persistent AF
(n=21, 84%). Patients presented with a significant symptom burden
(median European Heart Rhythm Association [EHRA] class, 3; IQR, 2),
after having tried a median of two antiarrhythmic medications (IQR, 1),
including amiodarone in 22 patients (88%). Each subject (n=25) had
previously undergone PVI once, ten patients (40%) twice, whereas LA
roof and mitral isthmus lines had been performed in five (20%) and two
(8%) patients, respectively. The mean LA volume was 161 ml (IQR, 25),
whereas the median left ventricular ejection fraction measured 54%
(IQR, 10).
