Q

Describe the QUANTIFICATION rating scale

A
  1. normal/very small = posterior echo free space in systole
  2. small = posterior echo free space
  3. mod to large = anterior and posterior echo free space
  4. large = anterior and posterior space and swinging motion
  5. tamponade = RA collapse and swinging motion

Q

How can you distinguish pericardial effusion from pleural effusion?

A

-A left pleural effusion will extend posterolateral to the descending aorta
-A pericardial effusion will track anterior to the DA

Q

What is a TRANSUDATIVE EFFUSION?

A

Q

What is a EXUDATIVE EFFUSION?

Study These Flashcards
A

inflammation of vessel walls allow fluid and proteins/large particles to leave vessel (infection, pneumonia, autoimmune, cancer, lung injury)

17
Q

What is LOCULATED PE?

Study These Flashcards
A

localized pocket(s) of fluid

18
Q

What causes LOCULATED PE?

Study These Flashcards
A

isolated areas of pericardial sac adhere and trap fluid

19
Q

When is it common for LOCULATED PE to occur?

Study These Flashcards
A

post op and recurrent pericardial disease so always check all windows

20
Q

What is ATELECTASIS?

Study These Flashcards
A

collapse area of lung

21
Q

What is PNEUMONIA?

Study These Flashcards
A

inflammation/infection of the air sacs

22
Q

Name other PERICARDIAL MASSES

Study These Flashcards
A
  1. epicardial fat pad
  2. right pleural effusion
  3. fibrinous stranding
  4. metastatic PE
  5. pericardial cysts
  6. hematoma
  7. pseudoaneurysm
23
Q

What is CARDIAC TAMPONADE?

Study These Flashcards
A

occurs when pericardial effusion causes pressure in pericardium to exceed pressure in chambers impairing cardiac filling

24
Q

What is CONSTRICTIVE PERICARDITIS?

Study These Flashcards
A

visceral and parietal layers become adhered, thickened, and fibrotic impairing diastolic filling “acting like a rigid box” leading to decreased cardiac output

25
What are the signs and symptoms of CARDIAC TAMPONADE?
1. dyspnea and tachycardia(most common) 2. hypotension 3. cough 4. JVD 5. hoarseness, difficulty swallowing
26
What are the signs and symptoms of CONSTRICTIVE PERICARDITIS?
* diagnosis is often delayed bc symptoms occur late * 1. fatigue 2. malaise 3. dyspnea 4. JVD 5. hepatomegaly 6. ascites 7.peripheral edema
27
What types of AUSCULTATIONS are heard with CARDIAC TAMPONADE?
1. distant heart sounds (Becks Triad if accompanied with hypotension and JVD 2. pulsus paradoxus: systolic BP drops >10 mmHg when the patient inspires
28
What is EWARTS SIGN and when is it heard with?
- bronchial breathing and dullness to percussion at the lower angle of the left scapula due to the fluid collapsing the left lower lobe - cardiac tamponade
29
What AUSCULTATIONS are heard with CONSTRICTIVE PERICARDITIS?
1. distant heart sounds 2. diastolic pericardial knock - as ventricular inflow is abruptly stopped 3. pulsus paradoxus
30
What is KUSSMAUL'S SIGN and when is is it heard with?
- a rise in JVP on inspiration due to RV noncompliance pushing fluid back into the venous system - constrictive pericarditis
31
What are the ECHO FINDINGS fo CARDIAC TAMPONADE?
1. Large pleural effusion and swinging heart 2. RA systolic collapse ( <⅓ of systole) - RA intracardiac pressure is lowest in systole 3. RV diastolic collapse ( strong indicator for tamponade)- RV intracardiac pressure is lowest in early diastole 4. LV may appear hyperkinetic as it seeks volume to circulate 5. Reciprocal respiratory changes in ventricular volumes 6. Enlarged nonpulsatile IVC
32
What are the treatments for CARDIAC TAMPONADE?
1. treat etiology of tamponade 2. volume expansion 3. pericardiocentesis 4. pericardial window
33
What is PERICARDIOCENTESIS?
needle aspiration of pericardial that is echo guided to reduce complications
34
What are the 2D FINDINGS for CONSTRICTIVE PERICARDITIS?
1. Echogenic pericardial thickening may be evident, some suggest > 3mm 2. Binded or bound appearance a the epicardial pericardial border with lack of pericardial slide 3. Septal shift with inspiration (bouncing) 4. Normal to dilated atria due to chronic atrial pressure elevation 5. Dilated IVC and hepatic veins due to elevated atrial pressures
35
What are the M MODE FINDINGS for CONSTRICTIVE PERICARDITIS?
1. LV: multiple dense linear reflections posterior to LV “railroad track sign” 2. LV: diastolic septal or “Spanish” notch 3. LV: PW shows early diastolic descent followed by flattening (aka square root sign) 4. PV: exaggerated premature opening of PV
36
What are the DOPPLER FINDINGS for CONSTRICTIVE PERICARDITIS?
1. Significant respiratory change at the TV and MV > 25% (like tamponade) 2. Respiratory changes will be similar at other right and left heart locations 3. MV and TV demonstrate prominent E wave with rapid deceleration slope, and small A wave 4. May note diastolic flow reversal in hepatics 5. IVRT demonstrates respiratory changes with ↑ time in inspiration
