Question | Answer |
---|---|
Large pyramidal appendage is found? | Morphologic Right Atrium |
Small finger like appendage is found? | Morphologic Left Atrium |
The Valve that empties into the right ventricle is always named? | The Tricuspid Valve |
The valve that empties into the left ventricle is always named the? | Mitral Valve |
The Ventricle with the large apical trabeculations is ? | The Morphologic right ventricle |
the ventricle with the small trabeculations is ? | the Morpholoic Left ventricle |
Cardiac orientation is based on ? | the orientation of the apex of the heart |
How is sidedness of the heart determined | by the position of teh morphologic right atrium |
what is the sidedness of a normally positioned atria called | situs solitus |
what is the sidedness of a heart that is the mirror image of situs solitus called | situs inversus |
what is the it called when the heart has bilateral R or L atria | isomerism (right or left) |
What are the four main changes in circulation that occur in the neonate at birth | 1) Placental circulation is eliminated 2) Pulmonary resistance drops and flow increases 3) Ductus arteriosus closes functionally 4) Foramen ovale closes |
Clubbing of the fingers is a sign of? | cyanosis |
How can you remember what lesions are acyanotic | APV (a patent valve prevents cyanosis- any defect that starts with an A, P, of V is acyanotic) |
what defects are more common in females | PDA and ASD |
what defects are more common in males | Aortic coarctation and stenosis |
What are two examples of maternal diseases that can result in cardiac defects | poorly controlled diabetes and lupus |
What are two medications that are possible causes of cardiac defects | Lithium and phenytoin |
What are four complications that can occur as a result of Left to Right Shunting | Right sided heart failure, Pulmonary Hypertension, Late cyanosis (Eisenmenger), and paradoxical embolus |
What is Eisenmenger syndrome | when the pulmonary pressure reaches system levels and the shunt may switch to a right to left shunt with resultant cyanosis |
