Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For that, 70 patients with an indication for isthmus-dependent atrial flutter ablation will be randomized to conventional irrigated catheter ablation or porous tip irrigated catheter ablation. A ECG-Holter examination will be done at 1 month follow up after catheter ablation, 6 and 12 months.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Atrial flutter, irrigated catheter
Patients with isthmus dependent atrial flutter, undergone to catheter ablation with Thermocool® (Biosense Webster, Diamond Bar, CA) irrigated catheter
Atrial flutter irrigated catheter
A duodecapolar isthmic curve catheter will be introduced to demonstrate cavo-tricuspidal bidirectional block. We performed atrial flutter ablation with conventional irrigated Thermocool® (Biosense Webster, Diamond Bar, CA) catheter Continuous lesions from tricuspidal annulus to inferior vena cava will be realized and then complete isthmic block will be confirmed by bidirectional stimulation
Atrial flutter, porous tip catheter
Patients with isthmus dependent atrial flutter, undergone to catheter ablation with Thermocool® SF(Biosense Webster, Diamond Bar, CA) irrigated catheter
Atrial flutter porous tip catheter
A duodecapolar isthmic curve catheter will be introduced to demonstrate cavo-tricuspidal bidirectional block. We performed atrial flutter ablation with Porous tip Thermocool® SF(Biosense Webster, Diamond Bar, CA)irrigated catheter Continuous lesions from tricuspidal annulus to inferior vena cava will be realized and then complete isthmic block will be confirmed by bidirectional stimulation
