“…After the creation of lesions at the right atrial aspect of the tricuspid valve annulus in young pigs, a significant narrowing of the RCA lumen (25% and 40%, respectively) due to intimal thickening was found in 2 of 5 animals after 6 months. 4 The hypothesis that RFC ablation procedures may damage the RCA has been confirmed in a subsequent experimental study with the same animal model. 5 Right atrial lesions that extend to the adjacent right coronary artery and lead to coronary artery obstruction from increased fibrous tissue content in adventitia and media with additional intimal thickening were found in 3 of 8 animals after 12 months.…”

“…5 Multivariate analysis could not demonstrate an effect of energy delivery parameters on the resulting lesion volume. 4,5 Whether patients with Ebstein's anomaly of the tricuspid valve are at an increased risk to develop coronary artery lesions after RFC application remains speculative. There are no major differences in the tricuspid annulus/coronary artery relationship between patients with Ebstein's malformation and subjects with normal hearts.…”

“…A control angiography after 12 months should also be attempted in all children with Ebstein's anomaly who undergo ablation of atrioventricular APs. Considering the results of the experimental studies, 4,5 this recommendation may even be expanded to all children after the ablation of right free wall APs to provide more insight into the incidence of coronary artery stenosis after RFC catheter ablation in structurally normal hearts. In conclusion, there are substantial late tissue effects after catheter ablation with RFC in the young.…”

“…1 Obstruction of the right coronary artery (RCA) as a late sequelae after RFC application to the tricuspid valve annulus has been described in an animal model. 4,5 It has been inferred that in humans, ablation procedures that target right free wall APs may damage the RCA. 3 No permanent damage to the coronary arteries caused by RFC catheter ablation in pediatric patients has been reported in the literature.…”

“…Animal studies, however, suggest that RF lesions in the developing myocardium may have the potential to expand with time 6 and may effect coronary perfusion. 15 Thus, the potential for spontaneous arrhythmia resolution as well as the short-and long-term risks associated with infant RFCA have been arguments against infant RFCA.…”

Participating Members of the Pediatric Catheter Ablation Registry* Background-The objective of this study was to determine the indications, the safety, and the efficacy of pediatric radiofrequency catheter ablation (RFCA) in infants. Methods and Results-Data from the pediatric RFCA registry were reviewed. Between August 1989 and January 1999, 137 infants, defined by age 0 to 1.5 years (median 0.7 years; weight 1.9 to 14.8 kg, median 10 kg), underwent 152 procedures in 27 of 49 registry centers (55%), compared with 5960 noninfants undergoing 6610 procedures during a comparable period. Structural heart disease was present in 36% of infants, compared with 11.2% of noninfants (PϽ0.0001). RFCA in infants was performed more commonly for drug resistance or life-threatening arrhythmias than in noninfants. No differences were found between infants and noninfants in success for all tachycardia substrates (87.6% versus 90.6%, Pϭ0.11), for single accessory pathways (94.5% versus 91.5%, Pϭ0.4), or for total (7.8% versus 7.4%, Pϭ1) and major (4.6% versus 2.9%, Pϭ0.17) complications. Neither success for infants with a single accessory pathway nor complications for the entire infant group were related to weight, age, center size, or the presence of structural heart disease. Centers that performed infant procedures, however, enrolled more patients overall in the registry than those that did not perform infant procedures, and successful procedures in infants were performed by more experienced physicians than failed procedures. Conclusions-Compared with noninfants, RFCA in infants is usually performed for drug resistance or life-threatening arrhythmias, often in the presence of structural heart disease. The data support the use of RFCA by experienced physicians in selected infants. (Circulation. 2001;104:2803-2808.)
