MCHN MIDTERM TOPIC Flashcards
Alteration in circulation of blood that occurs during fetal development
Congenital disorder
where there is no mixing of unoxygenated and oxygenated blood
acrocyanotically
where unoxygenated blood mixes with oxygenated blood wheter cyanosis occurs or not
cyanotically
Small or moderate openings may be asymptomatic
Ventricular Septal Defect (VSD)
- Loud harsh murmur best heard left sternal border radiating throughout precordium
- Right ventricular hyperthrophy
- Cardiac enlargement
Ventricular Septal Defect (VSD)
Abnormal opening between right and left ventricles
Ventricular Septal Defect (VSD)
Left to right shunting due to incomplete closure of septum; pulmonary vascular resistance
Ventricular Septal Defect (VSD)
Machinery-like murmur best heard upper-left sternal border during systole and most diastole
Patent Ductus Arteriousus (PDA)
- Widened pulse pressure
- History fatigue, weak cry, breathlessness, feeding difficulties
- Increased number respiratory infections
Patent Ductus Arteriousus (PDA)
- Communication between pulmonary artery and aorta due to failure of ductus arteriousus to close after birth
- Left to right shunting; increased pulmonary vascular resistance
Patent Ductus Arteriousus (PDA)
- Episodes of sudden epistaxis
- Full, bounding pulses upper extremities
- Headaches
- Leg fatigue
Coarctation of the Aorta (CA)
Elevated pressure proximal to narrowed portion of lumen of aorta
Coarctation of the Aorta (CA)
- Weak or absent pulses in lower extremities
- Systolic murmurs
- Narrowing of aortic lumen
Coarctation of the Aorta (CA)
Left ventricle must generate higher than normal pressure to eject adequate stroke volume; reduces systolic pressure distal to coarctation
Coarctation of the Aorta (CA)
Systolic murmur best heard over second left intercostal space
Pulmonic Stenosis (PS)
Split S2 (a finding upon auscultation of the S2 heart sound, caused when the closure of the aortic valve and the closure of the pulmonary valve are not synchronized during inspiration
Pulmonic Stenosis (PS)
- Dyspnea if severe
- Fatigue if severe
Pulmonic Stenosis (PS)
Obstruction of flow from right ventricles to lungs
Pulmonic Stenosis (PS)
