Outcome of Intra-Atrial Re-Entrant Tachycardia Catheter Ablation in Adults With Congenital Heart Disease: Negative Impact of Age and Complex Atrial Surgery

摘要: Objectives The aim of this study was to determine the acute and long-term outcome radiofrequency catheter ablation (RFCA) for intra-atrial re-entrant tachycardia (IART) in adults with congenital heart disease (CHD), predictors these outcomes. Background Atrial myopathy can be progressive CHD contributes substrate IART. Although RFCA IART has been well described children adolescents CHD, it is unclear whether results are similar adult population. Methods Clinical records undergoing attempted were analyzed retrospectively. Multivariate analyses identified clinical procedural factors that predicted Results A total 193 procedures performed 130 patients (mean age 40 ± 13 years); 82 118 (69%) initially successful, defined as termination all circuits. use electroanatomic mapping associated a successful RFCA, whereas Fontan palliation Mustard repair an unsuccessful RFCA. Median follow-up 77 (≥2 months follow-up) after 3.7 years (range 0.2 10.2 years). recurrence noted 48%, cardioversion/reablation 42%, death 4%. Older independent recurrence. Conclusions In outcomes those reported younger cohorts. Complex atrial surgery limits success older higher risk
