Concerns about children and involved medical staff being exposed to radiation during the procedure should not be ignored. \u201cFluoroscopy integrated 3D mapping\u201d, a new 3D non-fluoroscopic navigation system software (CARTO Univu Module) could reduce fluoroscopy during the procedure. However, there are few studies about the use of this new technology on children. In the present study, we analyzed the impact of the CARTO Univu on procedural safety and fluoroscopy in a wide spectrum of tachyarrhythmias as compared with CARTO3 alone.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The data of children with tachyarrhythmias who underwent RFCA from June 2018 to December 2021 were collected.
