Cardiac Development Flashcards
The bulbus cordis forms
Smooth parts of ventricles
The endocardial cushion forms
Septum’s and valves
Left horn of sinus venous forms
Coronary sinus
Prosterior, subcardinal, and supracardinal veins form
IVC
Primitive pulmonary veins form
Right atria smooth
Right common cardinal vein and right anterior cardinal vein form
SVC
Right horn of sinus venosus forms
Smooth part of right atrium
Truncus arteriosus form
AA and PT
What is patent foramen ovale
Failure of septum primum/secundum to fuse. Left to right shunt
Neural crest and endocardial cell migrations form
Truncates and bulbar ridges
AA and PT
Examples Conotruncal abnormalities associated with failure of neural crest cells to migrate
Transposition of great vessels
Teratology of Fallot
Persistent truncus arteriosus
the aortic/pulmmonary and mitral/ tricuspid are derived from
Endocardial cushion
The allantois becomes the
Median umbilical ligament
The ductus arteriosus becomes
Ligamentum arteriosum
The umbilical vein becomes the
Ligamentum teres hepatis
