They account for 20% to 30% of all birth defects and include a broad spectrum of malformations, ranging from severe anomalies incompatible with intrauterine or perinatal survival, to lesions that produce few or no symptoms, some of which go completely unrecognized during life. Congenital heart disease most commonly arises from faulty embryogenesis during gestational weeks 3 through 8, when major cardiovascular structures develop The various structural anomalies in congenital heart disease can be assigned to three major groups based on their hemodynamic and clinical consequences: (1) malformations causing a left-to-right shunt; (2) malformations causing a right-to-left shunt (cyanotic congenital heart diseases); and (3) malformations causing obstruction. CLASSIFICATION OF CHD GROUP 1: LEFT TO RIGHT SHUNTS(ACYANOTIC CHD) a. Atrial septal defect(ASD) b. ventricular septal defect(VSD) c. patent ductus arteriosus (PDA) GROUP 2: RIGHT TO LEFT SHUNTS(CYANOTIC CHD) a. tetralogy of fallot b. tricuspid atresia c. truncus arteriosus d. transposition of great vessels GROUP 3: OBSTRUCTIVE LESIONS a. Aortic stenosis b. coarctation of the Aorta ...
