The Department of Emergency Medicine at Carolinas Medical Center is passionate about education! Dr. Michael Gibbs is a world-renowned clinician and educator and has helped guide numerous young clinicians on the long path of Mastery of Emergency Medical Care. With his oversight, the EMGuideWire team aim to help augment our understanding of emergent imaging. You can follow along with the EMGuideWire.com team as they post these educational, self-guided radiology slides or you can also use this section to learn more in-depth about specific conditions and diseases. This Radiology Reading Room pertains to Spontaneous Pericardial Effusion and is brought to you by Chelsea Wilson, MD, and Emily Lipsitz, PA-C.

The Chest X-Ray Mastery Project™

2. Disclosures
 This ongoing chest X-ray interpretation series is proudly sponsored by the
Emergency Medicine Residency Program at Carolinas Medical Center.
 The goal is to promote widespread mastery of CXR interpretation.
 There is no personal health information [PHI] within, and all ages have
been changed to protect patient confidentiality.

3. Process
• Many are providing clinical cases and presentations are then shared with
all contributors on our departmental educational website.
• Contributors from many Carolinas Medical Center departments, and now…
Brazil, Chile, and Tanzania.
• We will review a series of CXR case studies and discuss an approach to the
diagnoses at hand: PERICARDIAL EFFUSION.

16. Thoughts On Pericardial Effusions
• Think about the possibility of a pericardial effusion in patients with
chest pain, dyspnea, syncope or pre-syncope.
• Slowly accumulating pericardial effusions stretch the pericardium and
enlarge the cardiac silhouette on CXR. A careful comparison with old
CXRs is helpful.
• Rapidly accumulating pericardial effusions (e.g.: stab wounds, blunt
trauma) typically ARE NOT associated with cardiac silhouette
enlargement on CXR.
• The liberal use of bedside point-of-care ultrasound is diagnostic.

23. Prospective observational study of 968 patients undergoing heart
rhythm device implantation or upgrade who underwent echo before and
24h after operation:
• Pericardial Effusion documented in 98 patients (10%)
• 1.5% (n=14) of whom progressed to cardiac tamponade requiring
pericardiocentesis in 86% (n=12) and surgical treatment in 14% (n=2)

24. Risk Factors: Female gender and antiplatelet therapy
Protective Factor: Previous cardiac surgery

25. • Utilization of ventricular and atrial screw—in leads were associated with an
increase risk of post-procedural Pericardial Effusion (PE)
• Specifically an atrial active fixation lead was used in 86% of patients who
subsequently developed large PE with tamponade physiology

42. Three variables were independently predictive of pericardial effusion in late-stage CKD patients:
• Heart rate at admission, serum potassium and corrected calcium level
• Presence of any one of these abnormalities:
demonstrated 66% specificity and 55% sensitivity in identifying patients with pericardial effusion
• Presence of any two of these abnormalities:
demonstrated 97% specificity and 18% sensitivity in identifying patients with any pericardial effusion

46.  Rapidly accumulating pericardial effusions cause swift increases in intrapericardial
pressure and tamponade physiology.
 Slowly accumulating pericardial effusions gradually distend the pericardium and
symptoms can be delayed.
