Dextrocardia occurs as 1 case per 9000 persons, and in 2.7-5 percent of cases with congenital heart disease. Numerous types can be identified. SS exists in 33-50 percent of cases. In the past Tetralogy of Fallot was considered rare in dextrocardia, but other authorities have not found this to be true. The cardiac apex is usally projected over the lower hemidiaphragm. Neurological complications occur in 25 percent of congenital heart disease patients. Spontaneous cerebrovascular accidents, thromboses and abscess are observed in 24 percent of cases. Cerebral infarctions are related to the polycythemia, increased blood viscosity and cerebral vascular resistance, decreased cerebral blood flow and hypoxia. Preexistent neurocirculatory damage is characteristic. The brain scan and EEG of the patient favored a thrombotic infarction over an abscess. Extracardiac anomalies are common in dextrocardia.
