Pericardial effusion
Pericardial effusion▪ is an accumulation of fluid in the pericardial space,
with or without associated pericarditis.
Pericardial effusion
▪ can develop in patients with acute pericarditis or in association with a variety of systemic disorders.
▪ important implications ▪ for prognosis (pts with intrathoracic
neoplasm)▪ for diagnosis (myopericarditis or acute
pericarditis)▪ or both (as in Ao ascending dissection).
Etiology▪ Idiopathic
▪ Infections A. Viral - Coxsackie, echo, adeno, EBV, CMV, influenza,
varicella, rubella, HIV, hepatitis B, mumps, parvovirus B19
B. Bacterial - Staph, Strep, Haemophilus, Neisseria, Chlamydia, Legionella, TB, Salmonella, Lyme disease.
C. Mycoplasma
D. Fungal - Histoplasmosis, aspergillosis, blastomycosis, coccidiodomycosis, actinomycosis, nocardia, candida
E. Parasitic - Echinococcus, amebiasis, toxoplasmosis
Etiology▪ Cardiac
A. Early infarction pericarditis B. Late postcardiac injury syndrome
(Dressler's syndrome) C. Myocarditis D. Dissecting aortic aneurysm
▪ Trauma
▪ Iatrogenic - Catheter and pacemaker perforations, cardiopulmonary resuscitation, post-thoracic surgery
▪ Malignancy
Etiology▪ Autoimmune
A. Rheumatic diseases – SLE, RA, MCTD,scleroderma
B. Wegener's granulomatosis, PAN, sarcoidosis, IBD (Crohn's, ulcerative colitis), Whipple's, giant cell arteritis, Behcet's disease, rheumatic fever
▪ Drugs (Procainamide, isoniazid, or hydralazine,cromolyn sodium, dantrolene, anticoagulants, thrombolytics, phenytoin, penicillin, phenylbutazone, doxorubicin)
▪ Metabolic (Hypothyroidism - primarily pericardial effusion, Uremia, Ovarian hyperstimulation syndrome)
Diagnostic approach
▪History (suspect in all cases of acute pericarditis)
▪ECG
▪CXR/ CT chest
▪Echo is required for establishing dg
ECG - Electrical alternans.
▪ beat-to-beat shift in the QRS (and sometimes the P wave) axis, amplitude, and/or morphology.
▪ occurs in association with swinging of the heart, usually in a large pericardial effusion
ECG - Low voltage QRS
Low voltage
▪ is probably due to short-circuiting of cardiac potentials by the fluid surrounding the heart.
▪ Defined as
▪ QRS complexes ≤5 mm (0.5 mV) in all of the limb leads.
▪ +/-- low voltage in the chest leads, QRS amplitude of ≤10 mm in V1 to V6
CXR
CT chest
ECHO –confirms the diagnosis
▪ Small collections of pericardial fluid can be physiologic if visible during ventricular systole.
▪ Effusions > 25 to 50 mL are seen as an echo-free space throughout the cardiac cycle
ECHO
Hemodynamic compromise assesment
▪ Factors that determine the degree of hemodynamic compromise include
the volume of pericardial fluidthe rate at which the effusion accumulates
whether or not the pericardium is scarred or adherent.
Acute vs subacute cardiac tamponade
ACUTE
▪ Sudden onset
▪ chest pain and dyspnea, and is life-threatening if not promptly treated.
▪ JVD markedly elevated
▪ Hypotension due to the decline in CO
▪ heart sounds muted.
▪ effusion is relatively small.
SUBACUTE
▪ less dramatic process.
▪ asymptomatic or c/o dyspnea, chest discomfort or fullness, fatiguability.
▪ Peripheral edema in chronic tamponade.
▪ Hypotension with a narrow pulse pressure (limited stroke volume)/ preexisting HTN may remain hypertensive due to the increased sympathetic activity
Acute vs subacute cardiac tamponade
Question no. 1
▪ 67 yo M is evaluated for an asymptomatic large pericardial effusion that has persisted for 4 months. He denies chest pain, dyspnea, fever, chills, cough, edema, and weight loss. He has a 30-year history of HTN which he takes amlodipine. CXR performed 4 months ago to evaluate chronic cough demonstrated an enlarged cardiac silhouette. Lab results at that time included normal CBC, electrolytes, creatinine, BUN, TSH. ANA and PPD were negative. Chest CT scan was normal. Echo performed 4 and 2 months ago showed a moderate pericardial effusion, no evidence of tamponade, and normal left and right ventricular function and size.
▪ PE: temp is normal, BP 135/75 mm Hg, HR 76/min, RR 16/min. Estimated CVP less than 5 cm H2O. Cardiac examination reveals muffled heart sounds, an absent apical impulse, and no pericardial friction rub. Pulmonary auscultation reveals normal breath sounds.
▪ Echo shows a large circumferential pericardial effusion and no findings of tamponade, and is otherwise without change from 4 and 2 months ago.
Which of the following is the most appropriate next step in management?
A. Colchicine
B. Indomethacin
C. Pericardiectomy
D. Pericardiocentesis
E. Prednisone
Answer
▪ Correct : D
▪ A pericardiocenthesis should be done when an idiopathic pericardial effusion persists more then 3 months.
▪ An idiopathic pericardial effusion lasting less than 3 months in a stable patient requires no specific therapy, but serial echocardiography based on clinical status, as was done in this patient, is advisable.
Cardiac tamponade – clinical features to look for:
▪ sinus tachycardia, even in the absence of frank hypotension, may indicate significant hemodynamic compromise from tamponade and serve as an indication for immediate pericardiocentesis.
▪ Elevated jugular venous pressure
▪ Pulsus paradoxus — defined as an abnormally large decrease in systolic blood pressure (>10 mmHg) on inspirations
▪ Pericardial rub
▪ Kussmaul's sign — is the absence of an inspiratory decline in jugular venous pressure
Pulsus paradoxus
Question no. 2
▪ A 45 yo M is evaluated in ED for 3-day history of progressively worsening dyspnea on exertion to the point that he is unable to walk more than one block without resting. He has had sharp intermittent pleuritic chest pain and a nonproductive cough with myalgias and malaise for 7 days and has had orthostatic dizziness for 2 days. He is taking no medications.
▪ On PE: temp- 37.7°C (99.9 °F), BP 88/44 mmHg, HR- 125/min, and RR 29/min; BMI is 27. O2 sats at RA is 95%. Pulsus paradoxus is 15 mm Hg. Estimated central venous pressure is 10 cm H2O. Cardiac examination discloses muffled heart sounds with no rubs. Lung auscultation reveals normal breath sounds and no crackles. There is 2+ pedal edema. BP and HR are unchanged after a 500-mL intravenous normal saline challenge.
▪ Laboratory studies:
▪ Prothrombin time 12 s
▪ Activated partial thromboplastin time28 s
▪ Creatinine1.3 mg/dL (99.2 µmol/L); BUN 26 mg/dL (9.3 mmol/L)
▪ ECG: sinus tachycardia, diffuse low voltage, no ST-segment shifts.
▪ ECHO: shows a large circumferential pericardial effusion, right ventricular and atrial free wall diastolic collapse, normal LV systolic function, and EF of 70%.
▪ CXR shows an enlarged cardiac silhouette and no pulmonary infiltrates.
▪ Which of the following is the most appropriate treatment?
A.Dobutamine
B.Levofloxacin and tobramycin
C.Pericardiocentesis
D.Surgical pericardiectomy
Answer
▪ Correct answer: C
▪ This patient has examination findings that indicate cardiac tamponade. Physical examination reveals tachycardia, reduced blood pressure, distended jugular veins, elevated pulsus paradoxus (>10 mm Hg), and an unremarkable lung examination.
Malignant pericardial effusion
Etiology
▪ Neoplasm A. Metastatic – Lung, breast Ca, Hodgkin,
leukemia, melanoma
B. Primary - rhabdomyosarcoma, teratoma, fibroma, lipoma, leiomyoma, angioma
C. Paraneoplastic
▪ Radiation

▪ Karatolios K et al “Diagnostic value of biochemical biomarkers in malignant and non-malignant pericardial effusion”
▪ Biochemical parameters and tumor markers to discriminate malignant from benign effusion in 105 pts
▪ Malignant pericardial effusions had significantly higher pericardial fluid levels of the tumor markers CEA, CA 19-9, CA 72-4, SCC and NSE as well as higher pericardial fluid hemoglobin (p < 0.001), WBC, LDH
▪ None of the biochemical or cell-count parameters tested proved to be accurate enough for distinguishing malignant from benign effusions.
▪ However, measurement of pericardial CA 72-4 levels offered a high diagnostic accuracy for malignancy, particularly in bloody pericardial effusions.
Cytology in pericardial effusions
▪ Cytology and pericardial biopsy — whenever there is a reason to suspect malignancy.
▪ Especially important if the effusion is hemorrhagic, and there is no history of antecedent trauma
▪ Negative cytology should not be used to exclude the diagnosis of malignancy, particularly if the index of suspicion is high
▪ A positive cytology may be predictive of a poorer outcome
Outcome prediction
▪ Prognosis and status of the underlying malignancy — most patients with a symptomatic malignant pericardial effusion have a short life expectancy (median two to four months)
▪ Patients with breast cancer or hematologic malignancies had a better median survival (9 and 17 months, respectively) than those with lung cancer.
