pericardial disease Flashcards
What is cardiac tamponade?
pericardial fluid generates pressure and results in collapse of right side of heart and hinders venous return
Cardiac tamponade results in what pericardial disorders?
increased central venous pressure
-systemic cardiac output falls
What are the clinical signs of cardiac tamponade?
- lethargy
- respiratory difficulty
- collapse/syncope
- exercise intolerance
- vomiting
- abdominal distension
What are the physical exam findings of cardiac tamponade?
- muffled heart sounds
- tachycardia
- pulsus paradoxus
- right-sided CHF
- diminished perfusion
- pericardial friction rubs
- sloshing or gurgling sounds
Which statement on pericardial effusion is correct?
A. Syncope is an infrequent clinical sign
B. Vomiting is a potential clinical sign
C. Severity of cardiac tamponade is directly dependent on effusion volume
D. Results in left sided CHF
E. Blood pressure is generally normal
B. Vomiting is a potential clinical sign
C is wrong because it is dependent on effusion volume AND rate
What cardiac neoplasias can cause pericardial effusion?
- HEMANGIOSARCOMA
- heart base tumors
- mesothelioma
- lymphoma
What are the non-neoplastic causes of pericardial effusion?
- IDIOPATHIC PERICARDITIS
- septic
- fungal
- left atrial perforation
- coagulopathy
- CHF
The most common cause of pericardial effusion in dogs is? A. Hemangiosarcoma B. Heart base tumors C. Malignant mesothelioma D. Lymphoma E. CHF
A. Hemangiosarcoma
What can be done for right atrial masses?
- pericardiocentesis
- pericardectomy +/- mass resection +/- chemotherapy
Why are brachycephalic breeds predisposed to pericardial effusion?
A. They are predisposed to hemangiosarcoma
B. They commonly develop mesothelioma
C. They commonly develop heart base tumors
D. They have abnormal pericardial drainage
E. Brachycephalic breeds are not predisposed to pericardial effusion
C. They commonly develop heart base tumors
What is idiopathic pericarditis?
an inflammatory process of the pericardial membrane resulting in pericardial effusion
What is the prognosis for idiopathic pericarditis?
- excellent w/ pericardiectomy
- guarded with tap alone
You diagnose your first case of idiopathic pericarditis. What do you recommend for long term therapy following the tap?
A. Monitor for recurrence
B. corticosteroids
C. Tap 3 times, then pericardiectomy
D. Pericardiectomy
E. Indwelling catheter with recurrent lavage
D. Pericardiectomy
What are the etiologies for pericardial effusion in cats?
- CHF
- lymphoma
- FIP
- sepsis
- idiopathic
- uremia
- fluid overload
What are the etiologies for pericardial effusion in horses?
- IDIOPATHIC PERICARDITIS
- bacterial
- viral
- septicemia
- pneumonia and pleuropneumonia
- pleuritis
- traumatic pericarditis from penetrating wounds
- neoplastic causes (rare)
