Three-dimensional (3D) mapping systems have revolutionized the way electrophysiologists visualize arrhythmia circuits, plan ablation strategies, and deliver precise therapy in the catheterization lab. Instead of relying solely on fluoroscopy and two-dimensional views, modern 3D Mapping Systems reconstruct the atrial and ventricular chambers in real time, integrating electrogram data with anatomical geometry. This session is designed for cardiologists, electrophysiology fellows, nurses, and technologists who want to understand how to use advanced 3D platforms to shorten procedure times, improve safety, and enhance arrhythmia outcomes in clinical practice.

As ablation procedures become more complex and indications expand, demand for specialized Cardiology conferences and structured training continues to grow. This session explains how 3D mapping technologies capture activation maps, voltage maps, and substrate characterization, allowing operators to track catheters with minimal fluoroscopy and reconstruct arrhythmia circuits beat by beat. Faculty will discuss practical workflows for atrial fibrillation, atrial flutter, ventricular tachycardia, and premature ventricular complex ablation, demonstrating how 3D maps guide lesion placement, reveal gaps in prior ablation lines, and help identify non-PV triggers or scar-related circuits.

The session also explores integration of imaging modalities such as CT, MRI, and intracardiac echocardiography with 3D cardiac mapping workshops and systems. Participants will learn how pre-procedural imaging can be imported into mapping platforms, how to align anatomic shells, and how to incorporate autonomic ganglia, scar zones, and key anatomic landmarks into procedural planning. Operational aspects, including lab setup, staff roles, data storage, system calibration, and quality assurance, will be addressed to help centers build efficient, consistent workflows. Case-based discussions will highlight troubleshooting strategies, pitfalls, and ways to interpret mapping artifacts so that teams can avoid misdiagnosis and incomplete ablation.

Beyond the lab, this session emphasizes training, credentialing, and future directions in 3D mapping, including high-density mapping, noninvasive electrocardiographic imaging, and integration with artificial intelligence–driven decision support. Attendees will leave with a clearer understanding of how 3D mapping fits into a comprehensive arrhythmia program, from patient selection and pre-procedure planning to follow-up, recurrence reduction, and long-term rhythm management.
