Pericarditis Flashcards
This form of pericardial disease is characterized by the combination of a tense effusion in the pericardial space and constriction of the heart by thickened pericardium.
Subacute Effusive-Constrictive Pericarditis
Becks triad
- Hypotension
- Soft or absent heart sounds
- Jugular venous distension with prominent X descent but absent y descent
Greater than normal (10mmhg) inspiratory DECLINE in systemic arterial pressure
PULSUS PARADOXUS
PULSUS PARADOXUS is seen at
Cardiac tamponade
1/3 of constrictive pericarditis
Subacute Effusive constrictive pericarditis
2d echo confirms diagnosis and shows that tricuspid and pulmonic valve flow velocities INCREASED markedly during inspiration.
there Is late diastolic inward motion (collapse) of the right ventricular freewall and the right atrium
Cardiac tamponade
With simultaneous fever and precordial pain 10 to 12 days after a presumed viral illness with audible pericardial friction rub. With Increasd CRP and WBC. ECG showing ST segment Alterations and abnormal T waves that persist for years. What is the diagnosis?
Viral or idiopathic form of acute pericarditis
With myocardial injury with blood in the pericardium after cardiac operation. Px with fever, pleuritis and pneumonitis. Findings shows fibrinous pericarditis and pericardial effusion. What is the diagnosis and treatment?
Post cardiac injury syndrome
Tx: ASPIRIN AND ANALGESICS
IF with disabling recurrences: another NSAID, Colchicine or glucocorticoid
Pericarditis sec collagen vascular diseases such as
SLE, RA, SCLERODERMA, PAN
Generally with fever, chills, Septicemia, and evidence of infection elsewhere. Poor prognosis. Requires drainage and antibiotic treatment.
PYOGENIC PERICARDITIS
Pericarditis without pain
Uremic pericarditis
Pericarditis sec to neoplasticism diseases
Tb pericarditis
Px on chronic HD with normal BUN and CREA.
Dialysis associated pericarditis
Treatment of PERSISTENT uremic pericarditis
PERICARDIECTOMY
Most common primary ca that causes pericarditis due to neoplasticism diseases
LUNG BReast Malignant melanoma Lymphoma Leukemia
May cause acute pericarditis and or chronic constrictive pericarditis, no pain
Mediqstinal irradiation For neoplasm
or
post irradiation or neoplasm
Drug induced lupus
Procainamide
Hydralazine
This disorder results when the healing of an acute fibrinous or serofibrinous pericarditis or the resorption of a chronic pericardial effusion isfollowed by obliteration of the pericardial cavity with the formation of granulation tissue.
Chronic constrictive pericarditis
In developing countries, most common cause of Chronic constrictive pericarditis is
TB
pulses paradoxus is seen in
Pericardial tamponade
Massive pulmonary embolism
Severe obstructive lung disease
Tension pneumothorax
May be palpable at the brachial artery or femoral artery when the pressure difference exceeds >15mmhg
Pulsus paradoxus
True or false
Pulsus paradoxus can be difficult to measure in tachycardic and tachypneic patients
True
Murmurs that diminishes in length and intensity with valsalva maneuver
Austin murmur
Graham steell murmur
Murmur of PDA
Prominent x and y descent
Chronic constrictive pericarditis
Physical signs in Chronic constrictive pericarditis
- Broadbents sign (decrease apical pulse)
- Kussmauls sign ( venous pressure do not fall during inspiration)
- Pericardial knock -early S3
- Pulsus paradoxus in 1/3 of patients
ECG findings in Chronic constrictive pericarditis
Low voltage QRS complexes
Diffuse flattening or inversion of Twaves
P mitral din px w sinus rhythm
AF in 1/3 of patients
2d echo findings of Chronic constrictive pericarditis
Pericardial thickening
Atrial enlargement
Dilated inferior vena cava and hepatic veins
Only definitive treatment for Chronic constrictive pericarditis
Pericardial resection
Pre-operative management for px >50 years old to exclude CAD
Coronary angiography
Tense pericardial effusion + constrictive pericarditis
Subacute effusive constrictive pericarditis
This chronic infection is a common cause of chronic pericardial effusion, especially in the developing world where active tuberculosis and HIV are endemic.
Tuberculous pericarditis
