Abstract
Threedimensionalmapping(3Dmapping)hasbeenutilizedtoenhancesafetyandefcacy
of electrophysiology (EP) study and ablation for patients with arrhythmia worldwide. Over the past
recent years, Cath laboratory Her Majesty Cardiac Center Faculty of Medicine Siriraj Hospital has
adopted this technique as a standard of care for our arrhythmia patients who undergo EP study
and ablation. Our data shows an increasing trend towards 3D mapping use across operators in our
institution. 3D mapping technologies including magnetic-based, current-based or hybrid-based
technologyareusedtofacilitatethefollowings: creationofanatomywithout usinguoroscopy,
creation of Local Activation Mapping (LAT), voltage mapping, Complex Fractionated Atrial
Electrogram (CFAEs) mapping, or creation of points during pace mapping. Moreover, 3D mapping can
process collected mapping points during mapping which can be viewed as isochronal activation,
propagation mapping or Ripple mapping. Recently, the real-time force-sensor ablation catheter has
been developed, which must be used along with 3D mapping system. This novel technology helps
ascertaining operators and their team to deal better with complex cases. Overall, 3D mapping not
only provides arrhythmia patients with better safety and outcome, but it also provides operators
andtheirteamwithsafetyduetothereductionofuoroscopicandproceduraltime.
