Common Congenital Cardiac Defects
| Cardiac Defect | Prevalence | Findings |
|---|
| VSD | 41.8 | Abnormal communication between left and right ventricles, causing shunt | | Atrial septal defect | 13.1 | Abnormal communication between left and right atria | | Tetralogy of Fallot | 4.7 | VSD, overriding aorta, pulmonary artery stenosis, right ventricular hypertrophy | | Coarctation of aorta | 4.4 | Narrowing of the aorta | | Endocardial cushion defect/atrioventricular septal defect | 4.1 | Missing “crux” of the heart in four-chamber view | | Patent ductus arteriosus | 2.9 | Open ductus arteriosus, persistent connection between the pulmonary artery and the aorta | | Hypoplastic left heart syndrome | 2.3 | Small left ventricle, aortic atresia, hypoplastic mitral valve | | Transposition of great arteries | 2.3 | Aorta arises from right ventricle and pulmonary artery from left. | | Total anomalous pulmonary venous return | 0.8 | Abnormal venous return of oxygenated blood from the lungs to right atrium instead of to the left atrium | | Persistent truncus arteriosus | 0.6 | Single overriding arterial trunk |
