Background:Anthracycline cardiotoxicity affects clinical outcomes, and its early detection using methods that rely on conventional echocardiography, such as left ventricular ejection fraction (LVEF) is difficult. This study aimed to evaluate the characteristics and the differences in cardiac dysfunction among childhood cancer survivors in 3 age groups using layer-specific strain analysis in a wide age range.

Background:There has been no nationwide survey on the prognosis of pediatric dilated cardiomyopathy (DCM) in Japan. Therefore, we designed this retrospective multicenter study to investigate the long-term survival rate in pediatric patients with DCM in Japan.Methods and Results:In this multicenter retrospective observational study, data were reviewed for 106 patients aged <18 years who had been diagnosed with DCM at any 1 of 18 Japanese institutions between 1990 and 2014. The median age at diagnosis was 2.0 years and the median duration of observation was 3.3 years. Most DCM patients were diagnosed because of symptoms of heart failure. On echocardiography, the median left ventricular end-diastolic dimension z score was 5.4 and fractional shortening was 0.10. Freedom from death or transplantation rates at 1, 3, 5, 10, and 20 years after diagnosis were 76%, 66%, 64%, 58%, and 43%, respectively. Freedom from death rates at 1, 5, 10, and 20 years after diagnosis were 81%, 75%, 72%, and 53%, respectively. The incidence of heart transplantation at 1, 5, 10, and 20 years after diagnosis was 6%, 15%, 20%, and 20%, respectively, suggesting that only 15% of patients in Japan underwent heart transplantation within 5 years of diagnosis.Conclusions:In Japan, the prognosis of pediatric DCM is poor and the rate of heart transplantation is low.
