What percentage of your ablation cases are done with cryo versus radiofrequency? In EP Lab Digest®’s March 2013 Spotlight Interview article, Nebraska Methodist Hospital in Omaha, Nebraska, describes their use of cryo technology:
“We use cryo for all of our atrial fibrillation ablations, which is the majority of the ablation that we do. All pulmonary vein isolation is done with cryo. Until recently, I used RF for ablation of complex fractionated atrial electrograms and linear lesions in persistent AF, but I have now transitioned to a PVI-only approach, and additional ablations (generally with irrigated RF) are only done if a non-pulmonary vein trigger is revealed with isoproterenol testing. The vast majority of our AVNRT cases are done with cryo. However, if only non-sustained AVNRT can be induced, I frequently use RF for a somewhat more clearly defined endpoint (junctional rhythm with slow pathway RF ablation). For typical atrial flutters, we use both 8 mm solid tip and irrigated RF.”
In our February 2013 issue, St. Vincent’s Medical Center in Bridgeport, Connecticut offered a different perspective:
“One hundred percent of our ablations are done using radiofrequency ablation. During our recent equipment upgrade, our EP lab obtained an IBI generator along with a Cool Point™ Pump (St. Jude Medical) that is utilized with irrigated ablation catheters during left-sided ablations.”
Of your ablation procedures in the EP lab, what percentage is done with cryo? What percentage is done with radiofrequency? Let us know!
