PROCEDURE

AT case 1.1

"In the case of AT at the time of ablation :~In the case of sinus rhythm restoration, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Inducibility will be tested but no ablation will be carried out and a DCC post AT mapping will be performed if necessary. The procedure will end up after these steps."

PROCEDURE

AT case 2.1

"In the case of AT at the time of ablation :~In the case of sinus rhythm restoration, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Then inducibility will be tested and all inducible AT will be mapped and ablated (max 5 consecutive AT)"

PROCEDURE

AT case 1.2

"In the case of AT at the time of ablation :~In the case of termination to another AT, a DCC will be performed. Thereafter, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Inducibility will be tested but no ablation will be carried out and a DCC post AT mapping will be performed if necessary. The procedure will end up after these steps."

PROCEDURE

AT case 1.3

"In the case of AT at the time of ablation :~In the case of AF deterioration, a DCC will be performed. Thereafter, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Inducibility will be tested but no ablation will be carried out and a DCC post AT mapping will be performed if necessary. The procedure will end up after these steps"

PROCEDURE

AT case 1.4

"In the case of AT at the time of ablation :~In the case of no AT termination, a DCC will be performed. Thereafter, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Inducibility will be tested but no ablation will be carried out and a DCC post AT mapping will be performed if necessary. The procedure will end up after these steps."

PROCEDURE

AT case 2.2

"In the case of AT at the time of ablation :~In the case of termination to another AT, ablation of the subsequent AT will be performed until sinus rhythm restoration. Thereafter, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Then inducibility will be tested and all inducible AT will be mapped and ablated (max 5 consecutive AT)"

PROCEDURE

AT case 2.3

"In the case of AT at the time of ablation :~In the case of AF deterioration, a DCC will be performed. Thereafter, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Then inducibility will be tested and all inducible AT will be mapped and ablated (max 5 consecutive AT)"

PROCEDURE

AT case 2.4

"In the case of AT at the time of ablation :~In the case of no AT termination, a DCC will be performed. Thereafter, PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. Then inducibility will be tested and all inducible AT will be mapped and ablated (max 5 consecutive AT)"

PROCEDURE

SR Case 1

"In the case of SR at the time of ablation:~PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. The CTI line will be performed in all patients with a ECG showing a typical counterclockwise flutter. Inducibility will be tested but no ablation will be carried out and a DCC post AT mapping will be performed if necessary. The procedure will end up after these steps."

PROCEDURE

SR Case 2

"In the case of SR at the time of ablation:~PV will be re-isolated if necessary and lines (CTI, roof and mitral) already blocked during the first procedure will be re-blocked if necessary. The CTI line will be performed in all patients with a ECG showing a typical counterclockwise flutter. Then inducibility will be tested and all inducible AT will be mapped and ablated (max 10 consecutive AT)"
