Atrial septal defects ASD occurs when the muscular wall (septum) separating the top two chambers of the heart is not properly close causing the flow of deoxygenated blood to the left atriun, three most common forms of ASD are: secundum, sinus venosus and primum defects. Ventricular septal defect the most common congenital heart defect occuring when the menbranous part of the IV septum dose not form Ebstein's anomaly defect of the tricuspid valves
Truncus arteriosus defect mostly associated with Iv setum defects
Atrioventricular canal defect
Pulmonary valve stenosis and Aortic stenosis
Coarctation of the aorta a narrowing in a portion of aorta
Tetralogy of Fallot is a combination of four (tetralogy) heart defects which mostly are are ventricular septal defect (VSD), pulmonary valve stenosis, a misplaced aorta and a thickened right ventricular wall.
Transposition of the great arteries reverse position of the pulmonary and aortic opening into the ventricles
