What are the signs and symptoms of left heart fail?

On CXR?

Will see progressive dysnpea and orthopnea (cough when lying down)

CXR: Cardiomegaly, blunting of costophrenic angle (pleural effusion) and batwing in the peri-hilum area, Kerley B lines and increased vasdcular shadowing. 

Caused by Left ventricle failure leading to increased left atrial pressure and increased ventricle filling pressure (or preload). This increased pressure transmists back to pulmonary capillaries==> fluid transudation into pulmonary interstial and alveolar spaces

When would you see the AV node take over to pace the heart? What would this look like on ECG?

If conduction between SA and AV node is impaired; may be d/t 3rd degree heart block

Changes will be bradycardia (SA has much higher firing rate, AV has slow firing rate at 45 bpm) and will see atria and ventricle depolarize ind of each other = AV dissocation

the QRS complexes will still be narrow bc ventricle depolarization is occuring normally.

Bacterial endocarditis FROM JANE

Bacteria FROM JANE ♥:

Fever

Roth spots
Osler nodes
Murmur
Janeway lesions Anemia
Nail-bed hemorrhage Embol 

4

What bacteria are implicated in Acute Bacterial Endocarditis?

 

Acute—S. aureus (high virulence).

Large vegetations on previously normal valves with rapid onset.

5

Pt comes to clinic with fever he's had for the past several days. During your PE you notice he has conjuctival pallor and small erythematous lesions on his hands and soles. You ask if they hurt and he states mostly not, except for a raised one on the pad of his thumb. While gathering history on the patient, he admits he has a pretty dangerous drug habit. 

What abnromatility would you expect to see in his heart?

BActerial endocarditis: signs of fever, anemia, Osler and Janeway lesions

IV drug use history: (Tricuspid valve implicated in IV drug use)

Think Acute and Staph Aureus; there will be large vegitaitons on previously normal valves

6

7

What type of bacterial endocarditis would you expect in a pts that has had recent dental procedures?

What would the vegitations in his heart look like?

Subacute—viridans streptococci

(low virulence). Smaller vegetations on congenitally abnormal or diseased valves. Sequela of dental procedures. Gradual onset. 

8

Most commonly implicated bacteria in culture negative bacterial endocartditis?

What about if the patient also has colon cancer?

What about a pt with prosthetic valves?

Culture Negs: Coxiella burnetii, Bartonella spp., HACEK (Haemophilus,

Actinobacillus, Cardiobacterium, Eikenella, Kingella) 

Colon cancer + endocarditis = S. Bovis

Prosthetic vavle + endocarditis = S. Epidermidis

9

Little girl shows up to the ER with her mother. This little girl has a fever of 102 and crys every time she tries to walk or lift her arms but she doesn't keep still and keeps moving and shifting. The mom states she would like you to avoid putting anything with preservitives in her daughter, that she and her husband are trying to raise them 'holistically'. What is the most immediate concern for this girl?

Child has Acute Rheumatic Fever = Group A B-hemolytic Strep. 

: FEVERSSS

Fever, Erhythma marginatum, Vavlular damage, ESR, Red hot joints, SubQ nodules, Syndham chorea

Death from Myocarditis is most concerning. 

10

What late sequale are seen in Rheumatic Fever?

What is the pathology for such complicated heart involvement seen in this diesase?

Late sequelae include rheumatic heart disease, which affects heart valves—mitral > aortic >> tricuspid (high-pressure valves affected most).

Early lesion is mitral valve regurgitation;l ate lesion is mitral stenosis.

Immune mediated (type II hypersensitivity); not a direct effect of bacteria. Antibodies to M protein cross-react with self antigens (molecular mimicry). 

11

What are Antisckow cells and Aschoff bodies?

Associated with Aschoff bodies (granuloma with giant cells ), Anitschkow cells (enlarged macrophages with ovoid, wavy, rod-like nucleus), anti- streptolysin O (ASO) titers.

seen in Acute Rheumatic fever

12

Beck triad (hypotension, distended neck veins, distant heart sounds), Increased HR, pulsus paradoxus. ECG shows low-voltage QRS and electrical alternans

Cardiac Tamponade: Compression of heart by fluid (e.g., blood, effusions) in pericardial space--> Decreased CO.

Equilibration of diastolic pressures in all 4 chambers.

13

14

What is Pulsus Parvus and when do you see it?

DECREASE in amplitude of systolic BP by > 10 mmHg during inspiration.

Seen in cardiac tamponade, asthma, obstructive sleep apnea, pericarditis, croup. 

15

Commonly presents with sharp pain, aggravated by inspiration, and relieved by sitting up and leaning forward. Presents with friction rub. ECG changes include widespread ST-segment elevation and/or PR depression. 

Acute pericarditis

 

16

Most common Primary Heart tumor in adult: Where is it locted and What does it look like? 

What is the most common Primary cardiac tumor in children?

Myxoma: 90% in Left Atrium adn often called a "ball valve"--> see mult syncopal episodes

Rhabdomyomas: often assoicated with Tuberous Sclerosis

17

What is the physiology behind Kussmal breathing?

INCREASE in JVP on inspiration instead of a normal decrease
Inspiration-->negative intrathoracic pressure not transmitted to heart--> impaired filling of right ventricle--> blood backs up into venae cavae--> JVD.

May be seen with constrictive pericarditis, restrictive cardiomyopathies, right atrial or ventricular tumors. 

18

Difference between Cherry and Strawberry hemangioma?

When do you see a cystic hygroma?

What about a Glomus tumor?

Cherry = adults; benign capillary hemangioma that doesn't regress

Strawberry = bengin in infants, does regress

Cystic = jabba neck; Turners

Glomus = painful red-blue under fingernails from Bartonella Henslae (mistaken for Kaposi)

32

What effects does Nitroprusside have on the cardiac pressure loop when given to pt with heart fail?

Nitroprusside is a balanced venous and arterial vasodialator: Reduces preload and reduces afterlooad but compliance and contractibilty are left unchanged

34

Young man comes to office with groin pain and swelling. He stated he had a sore on his penis but didn't think anything of it because it didn't hurt- 3 weeks later he started to have swelling in his inguinal region and inflammation of overlying skin and even draining ulcers. He stated that he had a fever around the same time as the groin pain. Cell scrapings from lesions show Cytoplasmic inculsion bodies. 

Dx

Chlamydia trachmatis: lymphogranulma venerum

Starts as painless ulcer--> progress to painful lymphadenopahty + ucleration: see small and shallow ulcers that heal rapidly

Intracytoplasmic chlyamydial inclusion bodies seen in epitheilal cells

Treponema pallidum = syphillus

36

Murmur is heard best at left sternal border when pt is leaning forward at the end of expiration. Described as a diastolic decrescendo murumor and heard in early diastole. 

Aortic Regurg

37

Pt has a peridoxical embolism lodge in their left cerebral artery and die. What sound will you hear on auscultation?

paradoxical implies it went through PDA: machine like murmur

*Atrial L--> R shunts cause WIDE and FIXED splitting of S2 that doesn't not change with respiration

38

Early diastolic decrescendo murmur is characteristic of this heart pathology. 

inhalation of amyly nitrate will reduce systemic arterial pressure and regurgitant glow thus lessening the murmur. 

Aortic Regurg
