Pathway Overview
14 steps
Algorithm Steps
14 total
01Start 02Action Recognize Clinical Features
Symptoms depend on rate of accumulation
- COMMON SYMPTOMS:
- • Dyspnea (90%) - most common
- • Chest discomfort/pressure
- • Orthopnea, cough
- SIGNS OF TAMPONADE:
- • Beck's triad: hypotension, JVD, muffled heart sounds
- • Pulsus paradoxus >10 mmHg
- • Tachycardia
- • Peripheral edema, hepatomegaly
03Action Urgent Echocardiogram
Bedside TTE is initial test of choice
- Quantify effusion size
- Small <10mm, Moderate 10-20mm, Large >20mm
- SIGNS OF TAMPONADE:
- • RA collapse in systole
- • RV collapse in diastole
- • IVC plethora (>21mm, <50% collapse)
- • Respiratory variation in mitral/tricuspid flow
- Circumferential vs loculated
04Decision Hemodynamic Compromise / Tamponade?
Clinical and echo evidence of tamponade
- Clinical tamponade: Hypotension, tachycardia, elevated JVP
- Echo signs: Chamber collapse, IVC plethora
- 78% of malignant effusions present with tamponade
05Action Urgent Pericardiocentesis
Life-saving intervention for tamponade
- Echo-guided preferred (subxiphoid or apical)
- Drain until hemodynamics improve
- Leave catheter for continued drainage
- Median drainage ~1000 mL
- Send fluid for: cytology, culture, glucose, protein, LDH
- Cytology positive in 80-90% of malignant effusions
06Decision Determine Etiology
Malignant vs non-malignant causes
- MALIGNANT (primary or metastatic):
- • Lung cancer, breast cancer (most common)
- • Lymphoma, melanoma
- • Mesothelioma (primary pericardial)
- NON-MALIGNANT in cancer patients:
- • Radiation-induced
- • ICI-associated pericarditis
- • Infection (immunocompromised)
- • Hypothyroidism, uremia
07Decision Recurrence Prevention Strategy
Based on prognosis and recurrence risk
- FACTORS FAVORING MORE DEFINITIVE PROCEDURE:
- • Rapid reaccumulation after pericardiocentesis
- • Reasonable prognosis (>3 months)
- • Good performance status
- PERICARDIOCENTESIS ALONE IF:
- • Very poor prognosis
- • First occurrence, slow accumulation
- • Bridge to systemic therapy effect
08Action Surgical Pericardial Window
For recurrent or loculated effusions
- Subxiphoid or thoracoscopic (VATS) approach
- Allows continuous drainage to pleural/peritoneal space
- 90-95% success rate in preventing recurrence
- Can obtain tissue for diagnosis
- Requires surgical fitness
09Action Follow-up Monitoring
Serial echocardiography
- Repeat echo in 1-2 weeks, then as clinically indicated
- Monitor for constrictive physiology
- Watch for recurrence symptoms
- Coordinate with oncology for systemic therapy
10Warning ⚠️ Prognosis Consideration
Malignant pericardial effusion indicates advanced disease
- Median survival ~4 months in symptomatic cases
- Treatment is primarily palliative
- Goals of care discussion important
- Palliative care involvement recommended
11Outcome Pericardial Effusion Managed
Continue surveillance and cancer treatment
12Action Intrapericardial Therapy
Sclerosis to prevent recurrence
- After drainage via indwelling catheter
- AGENTS (limited data):
- • Bleomycin
- • Tetracycline/doxycycline
- • Cisplatin (for lung cancer)
- 60-90% efficacy in preventing recurrence
- Pain, fever common side effects
- Path rejoins step 09Shared downstream outcome
13Action Systemic Anticancer Therapy
Treat underlying malignancy
- Lymphoma: Often responds well to chemotherapy
- Breast/lung cancer: Systemic therapy may control effusion
- ICI-associated: Hold ICI, give steroids
- May prevent recurrence if cancer responds
- Path rejoins step 09Shared downstream outcome
14Action Hemodynamically Stable
Time for additional workup
- CT chest with contrast
- Assess for pericardial masses/thickening
- Evaluate primary tumor status
- Consider etiology: malignant vs radiation vs treatment-related
- May observe small, asymptomatic effusions
- Path rejoins step 06Shared downstream outcome

Individual patient factors may require deviation from these recommendations.
Known Limitations
- Pericardiocentesis technique varies by institution
- Some effusions are treatment-related, not malignant
- Prognosis depends heavily on cancer type and stage
- Surgical options require cardiothoracic availability
