KODEX-EPD for CBA procedure
KODEX-EPD system is a novel dielectric-based 3-dimentional mapping
system. Since its first clinical use, it has been evolved in various
electrophysiological procedures including CBA
procedure7, 8, 10, 14, 15. Currently, CBA procedures
are performed with the guidance of fluoroscopy in most centers, which is
associated with potential harm of excessive radiation exposure.
Moreover, the fluoroscopic navigation limits the further application of
CBA technique. The KODEX-EPD system can provide real-time
high-resolution LA images, which largely facilitates the catheter
manipulation and PV occlusion verification in CBA
procedure9. Furthermore, it could accurately detect
various leak around the inflated balloon11, which
could avoid frequent angiography. A recent study showed that the
guidance of KODEX-EPD could effectively reduce the radiation exposure as
well as contrast dye use12. The median radiation time
of the present study was 25.3 min, which is longer than previous
reports12. The reasons may be: i) frequent pulmonary
venography to verify PV occlusion in our study; ii) the impact of
learning curve because these data were collected as soon as the
KODEX–EPD system became available in our center.
