Biotronik has reported that its AlCath Gold ablation catheter, together with the maximum voltage-guided (MVG) technique is optimal approach for atrial flutter ablation.
The post-hoc analysis, randomized, AURUM 8 clinical study, enrolling 463 patients undergoing cavotricuspid isthmus (CTI) ablation, is designed to study the effectiveness, by comparing AlCath catheter to platinum-iridium-tip catheter.
The results demonstrated that the MVG technique reduced ablation time, the number of lesions, fluoroscopy time, the procedure duration and the energy delivered compared with anatomic CTI ablation.
Biotronik managing director Werner Braun said Biotronik gold-tip ablation catheters are made of 99.9% pure gold.
"Compared with platinum, they provide four times greater thermal conductivity, maintain a cooler tip-temperature, facilitate fast and efficient lesion formation, and reduce coagulation resulting in reduced catheter exchange rates during the procedure," Braun added.
