Conotruncal Malfor
CHD study. Conotruncal malformations
| Question | Answer |
|---|---|
| Truncus arteriosus | single great artery that arises from the heart, overrides the ventricular septum, and supplies the pulmonary, systemic, and coronary circulations. the embryological structure (TA) never properly divides into the pulmonary artery and aorta |
| hemitruncus | one branch pulmonary artery originates from the ascending aorta and the other branch pulmonary artery courses normally from the main pulmonary artery that arises from the right ventricle. |
| aortico-pulmonary window | communication between the ascending aorta and the main pulmonary artery. The presence of pulmonary and aortic valves and an intact ventricular septum distinguishes this anomaly from truncus arteriosus |
| double outlet right ventricle (DORV) | occurs when both great vessels are anatomically committed to the RV |
| double outlet left ventricle (DOLV) | malformation in which both great arteries originate entirely or predominantly from the morphologic left ventricle |
| transposition l-loop | ? |
| transposition d-loop | ? |
| tetralogy of fallot | abnormalities due to maldevelopment of the truncus arteriosus characterized by(1)right ventricular outflow tract obstruction,(2)VSD,(3)overriding aorta, and(4)right ventricular hypertrophy.(TOF) is most common cyanotic congenital heart disease |
