Prediction of postnatal clinical course in primary congenital dilated cardiomyopathy

Abstract

BackgroundThe aim of this study was to investigate the prediction of postnatal prognosis using fetal and perinatal data in patients with primary congenital dilated cardiomyopathy (PCDCM), and to estimate the incidence of this disease.MethodsWe examined correlations between fetal or perinatal data and postnatal clinical course in a multicenter retrospective study of eight patients with PCDCM. Incidence was calculated in a population‐based study.ResultsAll patients developed heart failure at a median of 8 days (range, 0–43 days), and six patients died or required extracorporeal artificial heart therapy at a median of 67 days (range, 0–92 days). The cardiothoracic area ratio from fetal echocardiography, the Apgar score, and the standard deviation of birth weight correlated significantly with the date at onset of heart failure. However, no data correlated with survival. Cumulative incidence of PCDCM was calculated as 1.21 per 100 000 total births (95% confidence interval, 0.37 to 2.06).ConclusionsPrimary congenital dilated cardiomyopathy has a poor prognosis, but cardiothoracic area ratio from fetal echocardiography, body weight at birth, and Apgar score correlate with the timing of the onset of heart failure, and these indicators might therefore be useful for peri‐ and postnatal management.
