LEARNING OBJECTIVES
- Sustained re-entrant tachyarrhythmias treatment has become pivotal in the grown-up congenital heart patients clinical management.
- Cardiac LGE-MRI tissue characterization integrated with high definition electroanatomic map could allow fast recognition and effective treatment of substrate of tachyarrhythmias.
- Cardiac LGE-MRI areas were suggestive of post-surgical changes both in atrium and ventricle.
- High-density electro-anatomical map localized areas of slow conduction identifying conducting isthmuses of re-entrant arrhythmias.
