Pericardial Tamponade
Pericardial effusions with impending cardiac tamponade
Pericardial Effusions of infective or uncertain etiology where fluid analysis and/or culture are desirable
Recurrent persistent pericardial effusions.
To ameliorate symptoms related to pericardial effusions e.g. dypnea, esophageal compression.
Indications for Pericardiocentesis
![Page 3: How to Manage Complications: Technical Aspects of ...€¦ · before performing pericardiocentesis • Hemopericardium due to Type A Aortic Dissection • Traumatic hemopericardium](https://reader035.fdocuments.us/reader035/viewer/2022071012/5fcaefb186407220647732fa/html5/thumbnails/3.jpg)
Echocardiographic Findings of
Pericardial Tamponade
• Presence of a pericardial effusion
• Right atrial collapse in late diastole
• Right ventricular free wall collapse in early diastole
• Increase in E-wave velocity across tricuspid valve
during inspiration
• Decrease in E-wave velocity across mitral valve during
inspiration
• Inspiratory decrease and expiratory increase in diastole
pulmonary venous forward flow
• Dilated inferior vena cava without inspiratory collapse
![Page 4: How to Manage Complications: Technical Aspects of ...€¦ · before performing pericardiocentesis • Hemopericardium due to Type A Aortic Dissection • Traumatic hemopericardium](https://reader035.fdocuments.us/reader035/viewer/2022071012/5fcaefb186407220647732fa/html5/thumbnails/4.jpg)
• Elevated right atrial pressure
• Elevated intra-pericardial pressure (very similar to
right atrial pressure)
• Elevation and equalisation of left-right ventricular
filling pressure
• Loss of y descent of the right atrial pressure
waveform
• Arterial pulsus paradoxus (i.e. an inspiratory
decrease in excess of 10mmHg in systolic BP)
Hemodynamic Findings of
Pericardial Tamponade
![Page 5: How to Manage Complications: Technical Aspects of ...€¦ · before performing pericardiocentesis • Hemopericardium due to Type A Aortic Dissection • Traumatic hemopericardium](https://reader035.fdocuments.us/reader035/viewer/2022071012/5fcaefb186407220647732fa/html5/thumbnails/5.jpg)
Situations warranting special consideration
before performing pericardiocentesis
• Hemopericardium due to Type A Aortic Dissection
• Traumatic hemopericardium
• Hemopericardium secondary to post-myocardial infarct
ventricular free wall rupture
• Bleeding diathesis (Use of anticoagulants, raised
INR/APTT/PT, platelet count < 50,000)
• Recurrent pericardial effusions
• Purulent pericardial effusions
• Small pericardial effusions that warrant drainage
• Loculated pericardial effusions
• Posteriorly located pericardial effusions difficult to access
percutaneously

Techniques for Confirming Needle/Catheter
Placement in the Pericardial Space
• Monitor ECG signal from aspiration needle
– ST segment elevation/PVCs suggest epicardial irritation or
puncture; PR elevation/PACs suggest entry into RA
• Monitor pressure
– Intrapericardial pressure tracing observed (RV pressure waveform
suggests entry into RV)
• Inject agitated saline and observe for bubbles arriving in
pericardial space with echocardiography
• Inject contrast under fluoroscopic screening
• Advance an 0.035-inch J wire and observe it wrapping
around heart using fluoroscopy

• Close monitoring and observation
• Remain vigilant for development of complications
• Post-procedure CXR to exclude pneumothorax
• Analgesia as required for pericardial pain
• Catheter drainage: free drainage or intermittent aspiration
• Record volume draining at regular intervals
• Strict aseptic technique for catheter manipulations
• Flush with heparinised saline every 6-8 hours
• Minimise duration of catheter stay to reduce risk of infection
Management Post Pericardiocentesis
![Page 8: How to Manage Complications: Technical Aspects of ...€¦ · before performing pericardiocentesis • Hemopericardium due to Type A Aortic Dissection • Traumatic hemopericardium](https://reader035.fdocuments.us/reader035/viewer/2022071012/5fcaefb186407220647732fa/html5/thumbnails/8.jpg)
Management Strategies for Recurrent
Symptomatic Pericardial Effusions
• Repeat closed pericardiocentesis
• Percutaneous balloon pericardiotomy
• Surgical pericardial window creation
• Intrapericardial injection of sclerosing agents
• Adjuvant local and/or systemic chemotherapy for
malignant effusions
• Adjuvant radiation therapy (external or with
intrapericardial radionuclides)
• Combination of above strategies

Novel Percutaneous Pericardial Interventions
• Percutaneous balloon pericardiotomy
• Percutaneous pericardial biopsy
• Pericardioscopy
• Percutaneous pericardial access for epicardial
mapping and ablation of ventricular and
supraventricular arrhythmias
• Pericardial access for Left Atrium Exclusion
![Page 10: How to Manage Complications: Technical Aspects of ...€¦ · before performing pericardiocentesis • Hemopericardium due to Type A Aortic Dissection • Traumatic hemopericardium](https://reader035.fdocuments.us/reader035/viewer/2022071012/5fcaefb186407220647732fa/html5/thumbnails/10.jpg)
• Pull catheter as soon as appropriate or when volume
draining is <25-50mls/24 hours
• Pull catheter in event of fever/sepsis
• TTE before pulling catheter
• Surveillance TTE at appropriate intervals following
catheter removal
• Immediate TTE in event of deterioration in patient’s
hemodynamics

Percutaneous Balloon Pericardial Window
The panel on the left is a lateral projection showing the balloon (located between the two
highlighted dots) being advanced over the intrapericardial guidewire into a position where it
straddles the parietal pericardium. The panel in the middle shows the balloon inflated with an
evident ‘waist’ from surrounding parietal pericardium indicated by the arrow. The panel on the
right shows eventual release of the waist .
