Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Porous tip catheter use reduces procedure time and RF time in atrial flutter ablation with the same safety.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

New porous tip catheters appear more effective in atrial fibrillation ablation than conventional irrigated catheter, with the same safety. We could hypothesize porous tip irrigated catheters are more effective than conventional irrigated catheter, reducing procedure time and RF ablation time.We realize a randomized comparison study.

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.

Atrial flutter, irrigated catheter

Patients with isthmus dependent atrial flutter, undergone to catheter ablation with Thermocool® (Biosense Webster, Diamond Bar, CA) irrigated catheter

Group Type ACTIVE_COMPARATOR

Atrial flutter irrigated catheter

Intervention Type DEVICE

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
