Natural History of Congenital Heart Disease: Problems in Its Assessment with Special Reference to Ventricular Septal Defects

摘要: It is difficult to make prognoses and decisions on therapy of individuals with congenital heart disease (CHD) plan efficiently for medical services training programs because studies the incidence relative frequency different types CHD at birth, mortality rates, times death, prevalence rates in children adults are incomplete or unrepresentative. The present study assesses merits previous surveys attempts indicate best information about these rates. Specific attention has been directed data ventricular septal defect (VSD), an estimated least 20/10,000 live births; 10% died before 15 years age. There should thus be 18/10,000 surviving school VSD, yet most intensive show only half this number. This supports suggestion that there a high (perhaps 50%) spontaneous closure VSD during childhood. Spontaneous may also occur frequently afte...
