Key result
Pediatric non-compacted cardiomyopathy shows a heterogeneous course with risks of thromboembolism and severe arrhythmias.
Why the study?
Because non-compacted cardiomyopathy is rare and lacks well-defined diagnostic criteria, its natural history in pediatrics is poorly understood.
Observational (n=6)
No
This small pediatric series underscores that non-compacted cardiomyopathy in children has a highly heterogeneous presentation and can lead to severe cardiovascular events.
Supports vigilant monitoring for complications in affected children; leaves open identification of predictors in prospective registries.
Background: Non-compacted cardiomyopathy (NCCM) is characterized by hypertrabeculations and deep recesses in the left ventricle, with a heterogeneous clinical presentation, ranging from asymptomatic patients to those with heart failure (HF), thromboembolic events and arrhythmias with risk of sudden death. As it is rare and does not have well-defined diagnostic criteria, its natural history in pediatrics is poorly understood. This study describes the clinical presentation and clinical course of patients with NCCM.

Torbey et al. (2021) conducted an observational in Non-Compacted Cardiomyopathy (n=6). Non-compacted cardiomyopathy was evaluated on Clinical outcomes including thromboembolism, indication for heart transplantation, and sustained ventricular tachycardia. Pediatric non-compacted cardiomyopathy demonstrated a heterogeneous clinical course, ranging from asymptomatic to severe complications including thromboembolism and ventricular arrhythmias.
