ABSTRACT

In this chapter, the evidence and evolving strategies for catheter ablation as a treatment modality for VT in CHD are summarized. Specific anatomical features, changing surgical strategies and the consequences of consecutive surgical interventions important for the understanding of the VT substrate and for the planning of the mapping and ablation strategy are presented. Details are described for malformations with a higher propensity for VT, including tetralogy of Fallot, transposition of the great arteries, and Ebstein’s anomaly. The anatomical aspects are explained using post-mortem specimen and 3D reconstruction of in vivo image modalities. A practical and case-based guide to RFCA, including pitfalls and solution, is provided.
