    Abstract:
    PURPOSE: The prognosis of antenatally diagnosed congenital diaphragmatic hernia (ADCDH) is still very poor despite of innovation of various therapeutics. The authors reviewed their new therapeutic strategy of ADCDH from a viewpoint of cardiologic function. METHODS: The cardiac function in 19 cases of ADCDH was reviewed. The patients, at the age of 0 days, were divided into 2 groups, PG (+) and PG (-), according to the requirement of prostaglandin E1 (PGE1) to attenuate pulmonary hypertension. The left ventricular (LV) end-diastolic dimension (LV diastolic diameter index [LVDI]) and bilateral pulmonary arterial diameters (total pulmonary artery index [TPAI]) were measured on days 0 and 2. RESULT: Only 1 patient died of cardiac or respiratory failure, and the survivors' postoperative course was uneventful. Eleven patients needed inhalation of nitric oxide (NO), and in 9 of those, PGE1 was administered. The LVDI and TPAI of day 0 in PG (+) were significantly smaller than those in PG (-) and the controls. The LVDI increased from postnatal day 0 to day 2 in both PG (+) and PG (-). Although the LV was too small to output enough volume, the right ventricle successfully compensated for the low output through the ductus arteriosus, kept patent by NO and PGE1. CONCLUSION: For ADCDH with sever pulmonary hypertension, keeping patent ductus arteriosus with NO and PGE1 plays a critical role in obtaining excellent clinical outcome. Thus, the authors proposed a new therapeutic strategy for ADCDH based on a circulatory management.
