Study Notes
Prenatal Exposures and Congenital Heart Defects
- Prenatal lithium exposure can contribute to congenital heart defects.
- Prenatal alcohol exposure (fetal alcohol syndrome) can lead to congenital heart problems.
- Infants of mothers with diabetes during pregnancy are at increased risk of congenital heart defects.
- Congenital rubella can cause sensorineural hearing loss and cataracts in addition to heart defects.
- Marfan syndrome is a genetic disorder that can affect the heart.
- Turner syndrome is associated with potential cardiac problems.
- Williams syndrome is linked to specific cardiac malformations.
- DiGeorge syndrome (22q11) can cause cardiac anomalies.
- Down syndrome (Trisomy 21) is associated with congenital heart defects.
Specific Congenital Heart Defects
- Ebstein anomaly: characterized by a downward displacement of the tricuspid valve.
- Ventricular Septal Defect (VSD): a hole in the wall between the lower chambers of the heart.
- Atrial Septal Defect (ASD): a hole in the wall between the upper chambers of the heart.
- Patent Ductus Arteriosus (PDA): failure of the fetal blood vessel (ductus arteriosus) to close after birth.
- Tetralogy of Fallot: a combination of four heart defects.
- Transposition of great arteries: the major blood vessels are switched.
- Truncus arteriosus: a single large vessel emerges from both ventricles.
- Tricuspid atresia: the tricuspid valve is missing or abnormally formed.
- Septal defects (VSD, ASD, AV canal defect) include a range of holes in the cardiac septum.
- Pulmonary artery stenosis: narrowing of the pulmonary artery.
- Mitral valve prolapse (MVP): a condition where the mitral valve bulges into the left atrium during contraction of the heart.
- Aortic regurgitation: backward flow of blood through the aortic valve.
- Thoracic aortic aneurysm: a bulge in the aorta that can grow over time.
- Thoracic aortic dissection: a tear in the aorta, potentially life-threatening.
- Bicuspid aortic valve: a condition where aortic valve has two leaflets instead of three.
- Coarctation of aorta: a narrowing of the aorta, usually near the ductus arteriosus.
- Supravalvular aortic stenosis: narrowing of a section of the aorta above the aortic valve.
- AV septal defect: (endocardial cushion defect) affects both the AV valve and the septal area, potentially causing both ventricular and atrial septal damage.

Description
This quiz explores the impact of prenatal exposures on congenital heart defects. It covers various factors such as lithium, alcohol, maternal diabetes, and genetic syndromes that may contribute to these anomalies. Test your knowledge on the link between prenatal conditions and heart defects in infants.
