Summary of mapping studies showing similar properties of AF drivers. Current study*

Mapping Technique	AF type	No.	Atrial Location	Driver Dynamics	Impact of Ablation: Acute	Impact of Ablation: Chronic
FIRM Narayan 2012, Miller 2017, Spitzer 2016, Sommer 2016, Wilber	Paroxymsal, persistent and long standing persistent	3–4	LA 2/3 RA 1/3 PV 40%	Stable with precession for >10 mins	Term in 20–30% (2/3 to sinus)	Improves over PVI
Endocardial phase Alhusseini 2017 (used basket data, Kuklik 2017 method)	Paroxymsal, persistent and long standing persistent	3–4	LA 2/3 RA 1/3 PV 40%	More meander than FIRM	“Similar to FIRM”	“Similar to FIRM”
ECGI Haissaguerre 2014, Knecht 2017	Persistent	4–5	LA 2/3 RA 1/3 PV 40%	“Unstable” in same regions 24h (stable?)	Term in 40–70% (1/5 to sinus)	Improves over PVI
CartoFinder Daoud 2015 Schilling 2017	Paroxysmal and persistent	3–4	LA 2/3 RA 1/3 PV 40%	Stable with precession for >10 mins	Term in 20–30% (2/3 to sinus)	–
EGM Dispersion Seitz, 2017	Paroxysmal and persistent	4–6	LA 4/5 RA 1/5 PV 80%	No remaps	Term in >90%	Improves outcome
Dominant Frequency Atienza 2014	Paroxysmal and persistent	2–5	LA 4/5 RA 1/5 PV>70%	No Remaps	Term 30–40%	Equal to PVI
Body Surface DF Rodrigo 2017	Computer modeling	3	PV>70%	Greater Precession	N/A	N/A
CartoFinder Calvo 2017*	Long standing persistent AF	1.8	LA 2/3 RA 1/3 PV 21%	“Highly repetitive & recurrent rotational activity”	Term 15% (all to sinus)	70% freedom from AF after 12 months
