- AIM: The aim of the study was to assess the incidence, mortality and morbidity of dilated cardiomyopathy (DCM) and non-compaction of the left ventricle (LVNC) in Swedish children.METHODS: We reviewed hospital records of all children with dilated cardiomyopathy (DCM) or left ventricular non-compaction cardiomyopathy (LVNC) up to the age of 18 in the healthcare region of western Sweden from 1991 to 2015.RESULTS: In total, 69 cases (61% males) were identified. The combined incidence of DCM and LVNC was 0.77 (95% CI 0.59-0.96) per 100,000 person years. Children were divided into six groups and their outcomes were analysed depending on their aetiology. Idiopathic DCM was reported in 43% and familial dilated and left ventricular non-compaction aetiology was present in 32%. DCM due to various diseases occurred in 8%. DCM associated with neuromuscular diseases was present in 16%. The overall risk of death or receiving transplants in children with idiopathic and familial DCM was 30% over the study period and 21% died in the first year after diagnosis.CONCLUSION: The combined incidence of DCM and LVNC was similar to previous reports. Most children with idiopathic DCM presented during infancy and mortality was highest during the first year after diagnosis.
