Chapter 10: Pericardial Disease Flashcards
What are the LAYERS of the pericardium?
- visceral pericardium
- parietal pericardium
a. fibrous
b. serous
What are the FUNCTIONS of the pericardium?
- isolation
- barrier to infection
- reduced friction during contraction
- affects pressure distribution to the cardiac chambers
What causes pericardial disease?
- infection
- malignancy
- inflammatory
- trauma
- idiopathic
Define PERICARDITIS
inflammation of the pericardium
What are the ECHO FINDINGS for PERICARDITIS?
- increased echogenicity on 2D
- multiple parallel reflections posterior to LV on m mode
Define PERICARDIAL EFFUSION
build up of fluid around the heart. (pleura)
What are the CLINICAL SIGNS of PERICARDITIS?
- chest pain (typically worse when supine and with inspiration)
- widespread ST elevation on ECG
- pericardial friction rub on auscultation
- new or increasing pericardial effusion
What are the RATING SCALES for PERICARDIAL EFFUSION?
- quantification
- otto rating sale
- reynolds rating scale
Describe the QUANTIFICATION rating scale
- normal/very small = posterior echo free space in systole
- small = posterior echo free space
- mod to large = anterior and posterior echo free space
- large = anterior and posterior space and swinging motion
- tamponade = RA collapse and swinging motion
What is the OTTO RATING SCALE and what are the NORMS?
- based on the degree of separation between the parietal and visceral layer
small < .5 cm
mod .5 - 2 cm
severe > 2cm
What are the NORMS for REYNOLDS RATING SCALE?
Small -space systole/diastole posterior only < 1cm
Moderate -space systole/diastole poster/anterior < 1 cm
Large - space systole/diastole surrounds heart > 1cm
How can you distinguish pericardial effusion from pleural effusion?
-A left pleural effusion will extend posterolateral to the descending aorta
-A pericardial effusion will track anterior to the DA
What is PLEURAL EFFUSION?
build up of fluid in the space between your lungs and chest cavity
What are the 2 types of pleural effusion?
- transudative
- exudative
What is a TRANSUDATIVE EFFUSION?
high pressure pushes fluid out of vessels into interstitial (between cells), airways, pleural space
