The population of patients with congenital heart disease (CHD) continues to increases. The number of patients with arrhythmias associated with CHD is also growing and the issue of arrhythmia management in CHD is becoming more pronounced. Arrhythmias may originate from the congenital structural anomalies and the associated conduction system abnormalities per se. Even more, arrhythmia substrates are likely related to the consequences of previous operation or interventional procedures, chronic hypoxia, heart failure or cardiac fibrosis. Strategic approach to mitigate or eliminate the impacts from arrhythmias, i.e., heart failure and sudden death, is important and should be tailored to the patient individual.
Certain CHDs are known to be associated with characteristic rhythm disturbances, such as, twin AV nodes tachycardia in heterotaxy, and accessory pathways in congenitally corrected transposition of great arteries and Ebstein’s anomaly. Repaired tetralogy of Fallot are likely to have tachyarrhythmia due to late right ventricular dysfunction and adverse remodeling from electromechanical interaction. Atrial tachyarrhythmias increase with age in nearly all types of ACHD. With the advancement of medical technology, especially in the development of diagnostic tools, 3D mapping and catheter ablation, and cardiac implantable electronic devices technology, the treatment outcome is much improved.
Through sharing clinical cases, an in-depth overview of the latest treatment updates, recommendations and future trends in managing arrhythmias for CHD patients will be presented.
