Circ Arrhythm Electrophysiol. 2013;6:327-333. gap isolated CLINICAL PERSPECTIVE Ablations with lowest FTI (<400 gs) are responsible for quality of the entire circumferential lesion line around each PV, and thus also contributors toward unsuccessful outcome. Target CF: 20g (not less than 10g) Stability Minimum FTI 400 g. sec
A CF threshold of > 12 g predicts a complete lesion with high specificity (94%) and positive predictive value (91%). Heart Rhythm. 2015 Aug 10. pii: S1547-5271(15)01024-3. doi: 10.1016/j.hrthm.2015.08.010. [Epub ahead of print

Lancet 2015; 386: 672 79 Methods: Following PVI, 284 paroxysmal AF patients with dormant PV conduction were randomized to no further ablation or additional ablation until dormant conduction was abolished. Freedom from symptomatic AT after single ablation 69,4% 55,7% 42,3% Highly prevalent [284 of 534 pts, (53%)] Its elimination markedly improves arrhythmia-free survival without increased procedural risk. 27% absolute risk reduction number-needed- to-treat: 3.7 patients
2113 patients undergoing AF ablation were randomized to ATP-guided PVI or conventional PVI. 27.6% of patients had dormant PV conduction No significant reduction in the incidence of recurrent atrial tachyarrhythmias after catheter ablation for AF with ATP-guided PVI when compared with conventional PVI.

Population : 589 patients with symptomatic persistent AF (> 7 days and < 3 years) *** SOS *** 75% of patients constantly in AF > 6 months 1:4:4 : PVI, PVI+CFE, PVI+Lines Repeat ablation procedures allowed with the use of the identical randomized strategy as the first ablation Follow-up: Patients were followed for 18 mo Visit, ECG and 24 hour Holter at 3, 6, 9, 12 and 18 months Weekly TTM transmissions for 18 months
