Innovative technologies are being developed to make current ablation procedures safer and easier. Sometimes conventional ablation catheters cannot easily adapt to anatomical targets, making radiofrequency applications challenging, time consuming or even ineffective. The Cool Flex is a novel, flexible and fully-irrigated tip catheter with an innovative design and various angular orientations to better adapt the ablation tip to the surrounding tissue. Here, peliminary experience with this new ablation catheter is reported in the treatment of different tachyarrhythmias, including slow and accessory pathway ablation, cavotricuspid isthmus-dependent atrial flutter and atrial fibrillation. One or two radiofreqency applications may be sufficient to eliminate the arrhythmogenic substrate in most patients without complications.
