Key result
High-density mapping-guided ablation achieves stable rhythm at 12 months in 75% of ACHD patients.
Why the study?
Is high-density mapping-guided ablation using the Rhythmia system feasible and effective for arrhythmia management in adult patients with congenital heart disease?
Cohort (n=12)
Is high-density mapping-guided ablation using the Rhythmia system feasible and effective for arrhythmia management in adult patients with congenital heart disease?
High-density mapping for arrhythmia management in adult CHD patients allows rapid identification of scars but is limited by large atrial volumes and incomplete maps, yielding modest clinical success.

May support high-density mapping for ablation in adult CHD; leaves open need for larger prospective trials.
Ernst et al. (2018) conducted a cohort in Adult congenital heart disease with multiple arrhythmia substrates (n=12). High-density mapping-guided ablation (Rhythmia mapping system) was evaluated on Stable sinus rhythm or atrial paced rhythm. High-density mapping-guided ablation in adult congenital heart disease resulted in 75% (9 of 12) of patients maintaining stable sinus or atrial paced rhythm at a median 12 months follow-up.
