[Effective transplacental therapy in fetal cardiomegaly to prevent lung hypoplasia--case report]

In our referral center, 14,481 fetal echocardiography examinations were performed in 10,077 fetuses, in years 1994-2006. Fifty four fetuses presented cardiomegaly HA/CA > 0.6. There was one single survivor whose medical history is presented. Fetal cardiomegaly was detected by obstetrical ultrasound screening. In tertiary center HA/CA was evaluated as the following: 0.5 at 32 wks and 0.65 at 36 wks. In addition to cardiomegaly, pulmonary stenosis/atresia, dysplastic tricuspid valve with massive regurgitation were diagnosed. Digoxin was administered transplacentally for 33 days and, additionally, 30 min. oxygen was provided by mask for pregnant woman, 3 times per day. Spontaneous labour took place at 38 wks, with 3100 birth weight and 9 Apgar score. The newborn baby had only temporary tachypnoe, had a planned postdelivery therapy including prostin and cardiacsurgery and was discharged home at the age of 4 weeks in a good clinical condition. This is the first case in our institution of such massive cardiomegaly who did survived the neonatal period. The possible beneficial effects of transplacental digoxin and oxygen therapy are discussed, as well as fetal echocardiography monitoring using HA/CA and pulmonary venous Doppler flow.
