What is Acardia?
|
No heart
|
|
|
What is Ectopia Cordis?
|
Heart development in an abnormal location due to incomplete fusion of lateral fold resulting in improper body wall formation.
Typically fatal due to the exposure of the heart to external environment. |
|
|
Dextrocardia
|
Heart tube bends left instead of right resulting in transposition of heart and vessels. When accompanied with situs inversus, incidence of congenital defects is low.
|
|
|
Atrial Septal Defect
|
1)patent foramen ovale
2)endocardial cushion defect 3)common atrium |
|
|
Patent Foramen Ovale
|
most common ASD
no direct problems associated |
|
|
Endocardial Cushion Defect
|
due to incomplete fusion of endocardial cushions
septum primum fails to fuse with the endocardial cushions patent foramen primum |
|
|
Ventricular Septal Defects
|
1)membranous septal defect
2)Muscular septal defect 3)absence of IV septum |
|
|
Membranous septal defect
|
most common VSD
Failure of subendocardial tissue to grow from right side of fused endocardial cushions and fuse with muscular septum, and aorticopulmonary septum |
|
|
Muscular Septal Defect
|
May appear anywhere within muscular septum
|
|
|
Absence of IV septum
|
Rare condition resulting in a common ventricle
|
|
|
Bulbis Cordis Defects
|
1) Tetralogy of Fallot
2) Persistant Truncus Arteriosus |
|
|
What are the defects that accompany Tetralogy of Fallot?
|
1)pulmonary stenosis
2)VSD 3)overriding aorta 4)hypertrophy of right ventricle |
|
|
Persistant Truncus Arteriosus
|
results from failure of truncal ridges and aorticopulmonary septum to develop normally
results in a single arterial vessel giving rise to the pulmonary trunk and ascending aorta |
