| pubmed-article:11026578 | pubmed:abstractText | We reviewed our experience of fetal cardiac dextroposition in the absence of an intrathoracic mass. Ten cases were found by fetal echocardiography to have a normal cardiac axis, but the heart was shifted into the right chest and the amount of right lung tissue was reduced. At birth seven of the infants had confirmed structural heart disease (70%), including three with scimitar syndrome. Two infants had additional extracardiac anomalies (20%). Seven infants born at term had clinical pulmonary hypertension with a diagnosis of right lung hypoplasia in all of them. Two neonates died owing to significant heart disease (one with scimitar syndrome and the other with hypoplastic left heart syndrome). Of the three pregnancies that were terminated, the two fetuses with autopsies had severe right lung hypoplasia. Fetal cardiac dextroposition and right pulmonary artery hypoplasia in the absence of an intrathoracic mass are important signs of right lung hypoplasia, which can be associated with significant pathologic cardiac and extracardiac conditions. | lld:pubmed |
