Popis: Abstract Background Slow pathway (SP) ablation, in the context of atrioventricular node reentrant tachycardia (AVNRT) treatment could result in either complete elimination or only modification of the SP with ambiguity regarding associated benefits. Three‐dimensional electroanatomical mapping (3D‐EAM) may be used adjunctively aiming to complete SP elimination. Our purpose was to compare a 3D‐EAM‐based strategy targeting SP elimination to the conventional fluoroscopic approach with respect to clinical outcomes. Methods One hundred and two consecutive AVNRT patients (36 males, mean age 53.2 ± 13.7 years) underwent in two successive periods a conventional fluoroscopic ablation approach (n = 42) or a 3D‐EAM‐guided ablation focusing on complete SP elimination (n = 60). Results Several procedural parameters improved with 3D‐EAM use, including fluoroscopy time (2.4 ± 4.7 min vs. 13 ± 4.5 min), dose‐area product (1061 ± 3122 μGy × m2 vs. 5002 ± 3032 μGy × m2) and slow pathway elimination frequency (95% vs. 50%, all p
