The Texas Cardiac Arrhythmia Institute is a technological leader in the advanced 3D mapping of arrhythmias and other heart structures. Our physicians use the 3D mapping systems, in conjunction with CT imaging and robotic navigation technologies, to precisely locate catheters within the heart. Efficient and accurate catheter placement is one of the most important factors in a successful ablation, and also reduces procedure times and radiation exposure.

The Texas Cardiac Arrhythmia Institute plays a continuing role in the development of these technologies, helping manufacturers refine their latest products and add features to improve patient care.

The various 3D mapping systems employ electroanatomical navigation, which uses strategically placed electromagnets, patches that detect micro-impedance differences (small changes in electrical resistance) inside the body, or a combination of both to precisely guide catheters into place. Some mapping systems can even transform 2D images produced by intracardiac echocardiography (ICE) into detailed 3D models.

These systems can quickly and accurately generate 3D models of cardiac structures and arrhythmias, providing critical information to physicians during complicated anatomical cardiac ablations.
