Sudden cardiac death: risk stratification and betablocker

Hotspot Herzmedizin 2026 | Prof. Nicolaas Blom (Universiteit Leiden, Netherlands) gave a lecture at the congress on the topic of „Sudden cardiac death – risk stratification – does every patient need a betablocker?“. In the interview, he calls for personalization of risk stratification and discusses the most pressing issues for pediatric cardiology in the future, as well as international exchange in this field.

Take-aways

  • Risk stratification for sudden cardiac death in congenital heart disease must be personalized, as the patient group is highly heterogeneous and broad risk scores are often insufficient.

  • Scar-detecting MRI can non-invasively identify those at risk, enabling targeted treatment such as ablation and potentially avoiding unnecessary ICD implantation.

  • MRI-based risk assessment is already used in daily practice and is expected to be further incorporated into future ESC guidelines.

  • Life-course care is a key priority in pediatric cardiology, requiring structured long-term planning from childhood through adulthood and into older age.

  • Strong, well-organized transition programs between pediatric and adult congenital cardiology — such as those established in the Netherlands — are essential to ensure continuity of care and specialized surgical expertise across the lifespan.
