RESUMO
OBJECTIVE: To expose our 26 year experience in clinical management, interventional catheterization and surgical treatment of patients younger than 18 years with scimitar syndrome at the National Cardiology Institute. MATERIAL AND METHODS: We reviewed retrospectively all patients with scimitar syndrome in infancy between 1984 and 2010. Patients were divided in two groups: younger an older than one year at the time of the diagnosis. Medical records were analized, as well as chest radiography, electrocardiogram, echocardiogram and helicoidal tomography. All therapeutic procedures performed and their outcomes were analized. RESULTS: We studied 22 patients with scimitar syndrome, 20 of them with associated congenital heart disease. Congestive heart failure (p > or = 0.0001) and severe pulmonary hypertension (p > or = 0.002) were more frequent in patients younger than one year. We documented dextroposition and right lung hypoplasia in 14 patients, and aorto-pulmonary collateral arteries in 15 of them. Pulmonary hypertension was an important mortality risk factor (p > or = 0.007). CONCLUSIONS: Congestive heart failure and pulmonary hypertension are more frequent in patients younger than one year, and the former is a mortality risk factor. It is important to suspect this congenital heart disease in infants with dextroposition and congestive heart failure in order to provide an opportune treatment.
