Sudden cardiac death in congenital heart disease-a narrative review and update

Area of Science:

• Cardiology
• Pediatric Cardiology
• Congenital Heart Disease Research

Background:

• Congenital heart disease (CHD) encompasses a wide spectrum of conditions, from simple septal defects to complex heterotaxy.
• Despite surgical advances, CHD patients experience higher rates of sudden cardiac arrest compared to the general population.
• Existing interventions for bradyarrhythmias and tachyarrhythmias in CHD have limitations and adverse effect profiles.

Purpose of the Study:

• To review the current landscape of managing arrhythmias in congenital heart disease.
• To summarize recent advancements in pacing and cardioversion therapies for CHD patients.
• To identify future research directions for addressing sudden cardiac arrest in this population.

Main Methods:

• Literature review of congenital cardiac surgery.
• Survey of advances in cardiac pacing and cardioversion for arrhythmias.
• Analysis of unmet needs and limitations in current CHD management.

Main Results:

• The spectrum of CHD is highly variable, posing unique challenges for cardiac management.
• Sudden cardiac arrest remains a significant concern in the CHD population.
• Current pacing and cardioversion strategies offer partial solutions but have inherent drawbacks.

Conclusions:

• An unmet need persists for effective strategies to prevent sudden cardiac arrest in individuals with congenital heart disease.
• Further research is crucial to develop novel therapies that overcome the limitations of existing treatments.
• Future directions should focus on innovative approaches to arrhythmia management and sudden cardiac arrest prevention in CHD.
