“…Nevertheless, the 1 and 5-year freedom from AF at follow-up of this experience (98.1% and 89.2%, respectively) were comparable (or compared favorably) with those of other studies of Literature [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] where either biatrial (75% to 91% and 80.2%, respectively) or isolated LA ablation (57.8% to 95% and 72% to 81.1%, respectively) was performed. The present authors have no convincing arguments to give reason of these good results, which were consistent with the higher rate of dismission of any anti-arrhythmic drug of this experience with respect to other experiences (97.3% vs. 63% to 88.4%, at 1 year from hospital discharge) [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] . These results were even more unexpected considering that the line connecting the left pulmonary veins box to the LA appendage was waived and that an endocardial purse-string suture was used to perform the LA appendage obliteration (when performed).…”
