The Evolving Role of Insertable Cardiac Monitors in Patients with Congenital Heart Disease

Abstract

Insertable cardiac monitors (ICMs) have been used more frequently and in a wider variety of circumstances in recent years. ICMs are used for symptom-rhythm correlation when patients have potentially arrhythmogenic syncope and for less traditional reasons such as rhythm surveillance in patients with genetic arrhythmia syndromes or other diseases with high arrhythmia risk. ICMs have good diagnostic yield in pediatric patients and in adults with congenital heart disease and have a low rate of complications. Implantation techniques should take patient-specific factors into account to optimize diagnostic yield and minimize risk.
