There are few data on the incidence of echocardiographic (echo) abnormalities following catheter ablation in children in the era of 3D mapping. Wide practice variation exists regarding routine post-ablation echo. We hypothesized a low incidence of clinically significant echo abnormalities following SVT ablation in otherwise healthy children. Single center data from 2009 to 2015 were reviewed; routine post-ablation echo was standard practice. Cases were categorized as utilizing fluoroscopy alone (FLUORO) or 3D mapping with a low fluoroscopic protocol (CARTO3). Congenital heart disease was excluded. Outcomes of interest included new valvular abnormalities, pericardial effusions, and wall motion abnormalities. Findings were compared to baseline studies when available and classified as normal/unchanged, clinically insignificant, or clinically significant. Outcomes were compared between FLUORO and CARTO3 groups. Of 347 ablations, 319 (92%) underwent post-procedural echo: 57% male; 55% FLUORO; mean age 13.4 ± 3.6 years. The most common ablation target was an accessory pathway (AP) in 66% (n = 144 WPW, 66 concealed), followed by AVNRT in 32% (n = 102). Radiofrequency (RF) energy was utilized in 82% (n = 262). Post-ablation echos were normal in 81% (n = 259). Clinically insignificant findings were seen in 18% (n = 58), most commonly trivial-small pericardial effusions in 11% (n = 34). Two significant findings required additional follow-up or treatment. There were no cases of wall motion abnormalities or clinically significant effusions. There were no differences in frequency of echo abnormalities between the FLUORO and CARTO3 groups. Clinically significant echocardiographic abnormalities are rare following SVT ablation in children with structurally normal hearts, independent of the use of 3D mapping.
