A new ultrasound technology has now been introduced to guide ablation of atrial fibrillation, offering potential improvements in both the precision and safety of this therapy. AF is the most common type of heart rhythm disorder. With the new software imaging technology, the CartoSound? Image Integration Module and SoundStar? 3D Catheter, physicians now are able to visualize and create a whole new kind of “map” of the heart in order to perform atrial ablation.
