Study: NCT03343860

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 1.1
Description: 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.

Group type: ACTIVE_COMPARATOR
Intervention: AT case 2.1
Description: 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)

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 1.2
Description: 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.

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 1.3
Description: 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

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 1.4
Description: 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.

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 2.2
Description: 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)

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 2.3
Description: 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)

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: AT case 2.4
Description: 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)

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: SR Case 1
Description: 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.

Intervention type: PROCEDURE
Group type: ACTIVE_COMPARATOR
Intervention: SR Case 2
Description: 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)
