Table 1 Types of CHD and their descriptions.
Types | Description |
|---|---|
ASD | A hole in the wall (septum) that divides the upper chambers (atria) of the heart |
VSD | A hole in the wall (septum) that separates the two lower chambers (ventricles) of the heart |
AVSD | A large hole in center of the heart affecting all four chambers |
PDA | The ductus arteriosus fails to close after birth |
CoA | A part of the aorta, the tube that carries oxygen-rich blood to the body, is narrower than usual |
PS | A stenosis of main pulmonary artery and/or its branches |
TOF | A heart birth defect that includes 4 defects: ventricular septal defect, right ventricle outflow tract stenosis, aorta overriding and secondary right ventricular hypertrophy |
TGA | The main pulmonary artery and the aorta are switched in position, or “transposed” |
PAS | Left pulmonary artery originates from the right pulmonary artery, encircles the right main-stem bronchus, and distal trachea before entering the hilum of the left lung |
APVC | The lungs pulmonary veins don’t connect completely or partly to the left atrium like usual |
CAT | A single common blood vessel comes out of the heart, instead of the main pulmonary artery and aorta |
IAA | Aorta is not completely developed, part of the aorta is missing, leaving a gap |
SV | One lower chamber (ventricle) does not develop, and the heart has only one pumping chamber |
\(PA_{atresia}\) | The valve that controls blood flow from the heart to the lungs doesn’t form at all |
