Cardio Pathology Flashcards
Name the tetralogy of falot
Due to displacement of infundibular septum. “PROVe”
Stenotic Pulmonary artery
Right ventricular hypertrophy “Boot shaped”
Overriding aorta
Ventricular septal defect
Patient is presenting with late cyanosis what is occuring?
Likely a left to right shunt.
Pt is presenting with cyanosis early on in childhood what issue is occuring?
Likely a right to left shunt in the heart.
Think of the following
1 truncus arteriosis (one trunk)
2 Transposition (2 switched vessels)
3 Tricuspid atresia (3 = tri)
4 Tetralogy of Fallot (4 = tetra)
5 TAPVR (5 letters in the name) Total anomalous pulmonary venous return (pulmonary veins draining into the inferior vena cava instead of the left atrium)
What is the most common congenital cardiac defect?
Ventricular septal defect. Will remain asymptomatic for most of life. May self resolve or lead to left ventrical hypertrophy.
Patient is presenting with a very loud S1 and a wide fixed split S2.
Atrial septal defect.
What is the normal heart shunting in fetal life?
Normally is a right to left shunt with the fetal umbilical vein bringing oxygenated blood into the body.
Describe Eisenemnger syndrome
This occurs if the left to right shunt is not corrected, the shunt will eventually become a right to left from compensation leading to late cyanosis, clubbing, and polycythemia.
Patient is presenting with hyertension in the upper extremities and a weak delayed pulse in the lower extremities. Pt shows notched rib appearance on X-ray.
coarcation of the aorta!!
The aorta is narrowing at the insertion of the ductus arteriosis.
What constitutes as hypertension?
Systolic >140
Diastolic > 90
What constitutes as a hypertensive emergency?
Systolic >180
Diastolic >120
With end organ damage.
When looking at the kidney if you see a string of beads appearance what should you be thinking?
Renal artery stenosis likely to cause excessive release of renin leading to secondary hypertension.
When looking at the cornea you notice a light blue ring encircling the iris.
This is corneal arcus and is a sign of hyperlipidemia.
What is Monckeberge arteriosclerosis?
Caciification of the internal elastic lamina and media of arteries leading to vascular stifening without obstruction.
Will have a “Pipestem” appearance on X-ray. Does not obstruct blood flow as the intima is not involved.
Foam cells and fatty streaks in the vasculature are signs of what disorder?
Atherosclerosis. Or cholesterol fat accumulation in the arteries.
Thoracic aortic aneurysm is classically related to which microorganism?
Third degree Syphillis.
Which portion of the aorta is a Sanford Type A aortic dissection relating to?
The ascending aorta. May extend to the aortic aorta or descending aorta.
Only treatment here is surgery,
What portion of the aorta is a Sanford Type B aortic dissection relating to?
This relates to the descending aorta and or aortic arch. It spares the ascending aorta.
Treat with beta blockers and then vasodilaters.
What is stable angina?
this is a type of chest pain that is exertional and goes away with rest.
What is variant (prinzmetal) angina?
This is an arterial spasm usually brought on by a trigger and presenting with ST elevation.
Chest pain with ST depression and NO cardiac markers is a sign of what?
Unstable angina.
NSTEMI will present with cadiac markers.
Is noted with increased chest pain at rest.
What determins if a myocardial infarction presents with an elevated ECG ST segment vs a depressed ST segment?
Elevated ST segments will be shown with transmural infarcts (STEMI).
Subendocardial will display ST depression (NSTEMI) Cardiac biomarkers are diagnostic here.
What type of necrosis is seen with myocardial infarctions?
Coaguable necrosis.
What is the most specific cardiac marker for MI?
Tropinin 1 elevated 4 hours afterwords and remaining elevated for 7-10 days.
Which cardiac markr is useful for diagnosing reinfarction as levels return to normal after 48 hours?
CK-MB
