(BUSINESS WIRE)-- BIOTRONIKannounced today that its AlCath® Gold ablation catheter, together with the maximum voltage-guided (MVG) technique for radiofrequency catheter ablation of atrial flutter, has been shown to provide optimal clinical results. The post-hoc analysis data from the AURUM 8 clinical study was published in the Journal of Cardiovascular Electrophysiology(JCE).1
AURUM 82is the largest randomized atrial flutter ablation study in the world, with a total of 463 patients undergoing cavotricuspid isthmus (CTI) ablation in 19 clinical centers worldwide. The patients were randomized into two groups. They either received treatment using an 8-mm gold-tip catheter or an 8-mm platinum-iridium-tip catheter. The gold-tip catheter was associated with a significantly higher ablation success rate.
In the AURUM 8 study, 72 patients were treated with the MVG technique. A post-hoc analysis compared this subgroup with a patient group who underwent conventional anatomic CTI ablation. The MVG technique markedly reduced ablation time, the number of lesions, fluoroscopy time, the procedure duration and the energy delivered compared with anatomic CTI ablation. Furthermore, this subgroup analysis also confirmed previous results of AURUM 8: the MVG technique has even more advantages with a gold-tip catheter.
“The results of this post-hoc analysis show that the MVG technique is preferred over conventional CTI ablation due to an increased acute success rate, shorter ablation times and less charring,” stated Professor Dr. Thorsten Lewalterof the Isar Heart Center Munich, Medical Center for Cardiology and Internal Intensive Care. “Further analysis showed that using a gold-tip catheter with the MVG technique ensures optimal clinical and health economical outcomes.”
“This latest data confirms the results of a previous randomized study from the Gottsegen Gyorgy Hungarian Institute of Cardiology in Budapest published in 2009”3 commented Dr. Werner Braun, Managing Director at BIOTRONIK. “BIOTRONIK gold-tip ablation catheters are made of 99.9 percent 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.”
