Q

Pt is presenting with cyanosis early on in childhood what issue is occuring?

A

Likely a right to left shunt in the heart.

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)

Q

What determins if a myocardial infarction presents with an elevated ECG ST segment vs a depressed ST segment?

A

Elevated ST segments will be shown with transmural infarcts (STEMI).

Subendocardial will display ST depression (NSTEMI) Cardiac biomarkers are diagnostic here.

Q

ECG localization of an inferior Right coronary arter ifnarction would be seen across which leads?

A

II, III , and aVF.

26
Q

What is dresslers syndrome?

A

An autoimmune disorder resulting in fibrinous pericarditis. Can be seen several weeks following an MI,

27
Q

Sudden death in young athletes?

A

Hypertrophic cardiomyopathy.

28
Q

What is typically the cause of right sided heart failure?

A

It is usually secondary to left sided heart failure. Isolated right sided failure can be due to cor pulmone.

29
Q

Presence of hemosiderin laden macrophages in the lungs.

A

These are also known as heart failure cells seen with pulmonary edema due to left sided heart failure.

30
Q

When do you see nutmeg liver?

A

Hepatomegally most commonly seen with right sided heart failure. This is due to blood back up in the hepatic portal vein.

31
Q

Jugular distension is most commonly seen in which type of heart faiure?

A

Right sided the blood gets backed up into the external jugular vein.

32
Q

What is the most common cause of acute vs subacute bacterial endocarditis?

A

Acute is seen with S. aureus.

Subacute is seen with viridians

33
Q

What is tricuspid valve endocarditis most commonly associated with?

A

IV drug abuse.

Most commonly the mitral valve is affected by endocarditis.

34
Q

Rheumatic fever displays which type of hypersensitivity?

A

Type II immune related where antibodies directed to M protein of S pyogenes cross react with the tricuspid valve.

Treat wth penicillin.

35
Q

An ECG showing low voltage QRS and electrocal alternans with Beck’s triad of hypotension, distended neck veins, and distant heart sounds should point you in which direction?

A

Cardiac tamponade.

Look for the pulsus paradoxis where the amplitude of systolic blood pressure drops more than 10 mmHg with inspiration.

36
Q

“Tree Bark Aorta”

A

Tertiary syphilis leading the calcification of the aortic root.
Can lead to anyeurism, or aortic insuffiicency.

37
Q

What is the most common primary cardiac tumor in adults?

A

A myxoma commonly described as a ball valve obstruction in the left atria.

rhabdomyomas is the most frequent cardiac tumor in children.

38
Q

What is Kusmauls sign?

A

Increase in Jugular venous pressure on inspiration instead of the normal decrease.
Seen in constrictive pericarditis, or right atrial/ventricular tumors.

39
Q

Bacillary angiomatosis is related to which microbe and what sets it apart from kaposi sarcoma?

A

Caused by Bartonella heneslae infections.
It is set apart by having a neutrophilic infiltrate.

Kaposis sarcoma has a lymphoctyic infiltrate.

40
Q

What infiltrate is seen in kaposis sarcoma?

A

KS has a lymphocytic infiltrate.

41
Q

What is tricuspid atresia?

A

Absence of the tricuspid valve and hypoplastic RV

Requires both ASD and VSD for viability.

42
Q

What keeps the ductus arteriosis patent in utero?

A

It is kept open via prostaglandins.
If the child is born with a patent ductus arteriosis, it can be closed by use of an NSAID to block the prostaglandins such as endomethacin.

43
Q

turners syndrome

A

Bicuspid aortic valve

Coarcation of the aorta

44
Q

Ebstein anaomoly

A

Seen in infants that have been exposed to lithium

45
Q

22q11 syndromes

A

truncus arteroisus

Tetralogy of fallot

46
Q

Plaques or nodules filled with lipid-laden histiocytes in the skin

A

Xanthomas

47
Q

Monkberg arteriosclerosis

A

Uncommon effecting the medium sized arteries
Calcification of internal elastic lamina of the arteries leading to vascular stiffening without obstruction.

Look for the pipestem appearance on X-ray.
This does not disrupt blood flow through the arteries.

48
Q

Difference between arteriosclerosis and atherosclerosis

A

Arteriosclerosis is hardening of the arteries with arterial wall thickening and loss of elasticity. (Arterioslcerosis vs monckeberg)

Atherosclerosis is disease of teh elastic arteries and large-medium sized muscular arteries. Typically due to a build up of cholesterol plaques.

49
Q

What is inmportant in the pathogenesis of atherosclerosis?

A

Inflammation leading to endothelial dysfunction and macrophages accumulating LDL becoming goam cells.
Fatty streaks are seen on the vascular walls and smooth muscle migrates to the walls to try and repair.

50
Q

Sudden onset tearing chest pain radiating to the back with uneven BP in both arms.

A

Aortic dissection.

51
Q

ST elevation with heart pain can be

A

MI
or
Prinzmetal angina.
Differentiate between the two with carciac markers in the blood.

52
Q

difference between ST elevation and ST depression with cardiac markers.

A

Both mean there is an MI when cardiac markers are present.
(Stable angina can raist ST and unstable can depress but no markers)

ST elevation is with a transmural infarction.
ST depressions occur with a sub endocardial infarction.

53
Q

What is dresslers syndrome?

A

2 weeks to several months after an MI Scar tissue forms causing a rubbing sound on auscultation.
It is driven by an autoimmune reaction

54
Q

Give a general treatment to acute coronary syndrome

A

NSTEMI + Unstable angina
Anticoagulation (heparin)
Antiplatelet therapy (aspirin + Clopidogrel)

55
Q

Which heart sound is related to a dilated cardiomyopathy?

A

S3

56
Q

What type of hypertrophy is seen with dilated cardiomyopathy?

A

Eccentric lenghtening added in series

57
Q

What heart sound is found in hypertrophic cardiomyopathy?

A

S4

58
Q

Leads to sudden death in young athletes

A

hypertrophic cardiomyopathy

Highly genetic.

59
Q

What is lofflers syndrome related to?

A

Restrictive cardiomyopathy.

Diastolic dysfunction ensues and ECG may display low voltage despite having a thick myocardium.

60
Q

Roth spots on the retina, janeway lesions on the palm or sole, osler nodes on the finger or toe pads and splinter nail hemorages are all signs of what disorder?

A

All signs of bacterial endocarditis.

61
Q

Sharp pain upon inspiration releived by sitting up and leading forward. Frictional rub and widespread ST segment elevations or depressions.

A

Sign of acute pericarditis.
Most commonly viral (Coxsackie) or SLE
Radiation therapy and rheumatoid arthritis or uremia can cause it as well.

62
Q

Raynoud phenomenon color change

A

White
Blue
REd

Treat with calcium channel blockers.
