Case 1: Acute Pericarditis with Pericardial Effusion

Patient Presentation

Demographics: 32-year-old male

Chief Complaint: Sharp chest pain for 2 days

History of Present Illness: A 32-year-old previously healthy male presents with sharp, stabbing chest pain that started 2 days ago. The pain is worse when lying flat and improves when sitting forward. He reports a recent viral upper respiratory infection 1 week ago. He also notes low-grade fever and fatigue.

Physical Examination:

  • Vital Signs: BP 118/72 mmHg, HR 98 bpm, RR 18/min, Temp 38.1°C, SpO2 98% on room air
  • General: Anxious-appearing male, sitting forward
  • Cardiovascular: Pericardial friction rub heard at left lower sternal border (three-component scratchy sound)
  • Lungs: Clear to auscultation bilaterally
  • JVP: Normal

Workup

  • ECG: Diffuse ST-segment elevation with PR depression in multiple leads (concave upward ST elevation)
  • Echocardiogram: Small pericardial effusion (0.8 cm), normal LV function
  • Labs:
  • Troponin I: 0.08 ng/mL (mildly elevated)
  • WBC: 11,200/μL
  • ESR: 45 mm/hr
  • CRP: 6.2 mg/dL

Diagnosis

Acute viral pericarditis with small pericardial effusion and mild myopericarditis

Anatomical Correlation: The pericardium consists of the fibrous pericardium (outer layer) and serous pericardium (parietal and visceral layers). The pericardial cavity normally contains 15-50 mL of fluid. Inflammation of the pericardium causes the characteristic friction rub heard when roughened pericardial surfaces rub together.

Treatment

  1. NSAIDs (Ibuprofen 600 mg TID for 1-2 weeks)
  2. Colchicine 0.5 mg BID for 3 months (reduces recurrence)
  3. Activity restriction until symptoms resolve
  4. Serial echocardiography to monitor effusion
