Term
Cor trilpculare Biventriculare
Definition

-most serious abnormality of Atrial Septal Defects

- complete absence of atrial septum

 

Term
Atrial Septal Defects (ASD) can be due to
Definition

1. normal septum formation but excessive resorption of septum primum

2. Absence of septum secundum

 

Term
Tricuspid Atersia (ASD)
Definition

-obliteration (destruction) of the rt. atrioventricular orifice (passage)

-Characteristics

* patent oval foramen

* ventricular Septal defects

* underdeveloped right ventricle

* Left ventricle hypertrophy

 

Term
Ventricular Septal Defects
Definition

1. Defect of the membranous part of intermuscular septum = mixed blood in pul. trunk

2. defect of muscular part of Intermuscular septum aka Swiss Cheese VSD

3. Absence of Interventricular septum

Term
Dextrocardia
Definition

The heart and the vessels are reversed due to heart tube bending to the left durign development instead of right

*** compatible w/ life

Term
Ectopia Carditis
Definition

-rare

- Heart is in abnormal position

- Heart is either totally or partially exposed

- Widely separated sternum

- Open pericardial sac

- Death in few days after birth

Term
Stenosis
Definition
failure of the heart valves to open fully
Term
Insufficiency /regurgitation
Definition
failure of the valve to close completely
Term
Both stenosis and Regurgitation produce _____, which results in _____, that produce produce vibrations which are audible as _____
Definition

1. Turbulence

2. Eddies -- small whirlpools

3. murmers

Term
Mitral, Aortic Valve calcification results from
Definition

1. degenerative process in teh cardiovascular fibrous skeleton

2. enhanced stress and abnormal valve motion accelerate degenerative process, leading to premature calcium deposition

Term
Valvular Thickining/Sclerosis
Definition

- commonly involved involves the arotic and mitral valve

- thickining usually involves chrodae tendineae, valve cusps & leaflets

Term
Valvular Stenosis (aortic)
Definition
Term
Valvular Atresia (arotic)
Definition
Term
Pulmonary Valvular Atresia/Stenosis
Definition
Term
Conotruncal Defects: Transposition of Great Vesels
Definition

-Failure of spiral conotruncal septum to follow its course causes:

1. Aorta to originate from right ventricle

2. Pulmonary Trunk orginates from left ventricle

Term
Conotruncal Defects: Persistent Truncus Arteriosus
