Johnson & Johnson has outlined plans to introduce a new artificial intelligence-enabled module within its cardiac mapping ecosystem, reinforcing its long-standing focus on electrophysiology innovation. The company confirmed that the CartoSound Sonata module will be formally presented at Heart Rhythm Society (HRS) 2026, marking a significant step in the evolution of cardiac mapping technologies. Designed to work within the Carto platform, the module applies AI to convert intracardiac echocardiography (ICE) images into highly detailed anatomical maps, allowing physicians to construct accurate visual models of multiple heart chambers while also enabling automated identification and labeling of cardiac structures.
The new module is engineered to integrate with Johnson & Johnson’s SoundStar Crystal (2D ICE) and NuVision Nav (4D ICE) ultrasound catheters, extending its applicability across a range of clinical scenarios. It is intended to support both the planning phase and real-time execution of procedures targeting various heart rhythm conditions, including AFib, ventricular tachycardia and complex concomitant interventions. By embedding AI into the workflow, the company aims to streamline imaging processes and improve procedural efficiency, further strengthening the role of cardiac mapping as a central tool in electrophysiology practice.
Johnson & Johnson continues to align its mapping innovations with its broader therapy platforms. The Carto system remains a foundational component of the company’s Varipulse pulsed field ablation (PFA) platform, which is used in the treatment of AFib. At HRS 2026, the company is also set to present new real-world data related to Varipulse, following the recent introduction of its next-generation platform in Europe. These developments reflect a coordinated strategy to integrate imaging, mapping and therapeutic capabilities within a single connected ecosystem.
“In my experience, CartoSound Sonata elevates imaging capabilities by streamlining the process of building detailed maps of the heart across multiple chambers using both 2D and 4D ICE technologies, even during the most complex concomitant procedures. This new module continues to demonstrate the power and versatility of the CARTO System and is a clear example of its continued evolution as a key platform in electrophysiology,” said Luigi Di Biase, system director, Electrophysiology, Montefiore Health System.
“For 30 years, the Carto system has led progress in electrophysiology, serving as the foundation of a connected platform that brings together imaging, mapping, and therapy. Looking into the future, we are decisively moving forward with continuous advancements toward new frontiers in cardiac mapping. As we introduce CartoSound Sonata and continue to progress our PFA technologies, we remain committed to innovation that improves how arrhythmias are understood and treated, while evolving and pushing what’s possible in AFib care,” said Michael Bodner, company group chair, Electrophysiology & Neurovascular, MedTech, Johnson & Johnson.
