Study Notes
Pericardial Diseases Overview
- Pericardial diseases include acute pericarditis, constrictive pericarditis, pericardial effusions, and cardiac tamponade.
- Acute pericarditis is an inflammation of the pericardium, often leading to constrictive pericarditis if recurrent.
- Constrictive pericarditis typically results from chronic or repeated acute pericarditis episodes.
Causes of Pericardial Diseases
- The causes of acute and constrictive pericarditis are often the same.
- Infectious agents are significant contributors, commonly categorized under idiopathic cases.
- The most frequent viral causes include:
- Coxsackie B virus
- SARS-CoV-2 virus (responsible for COVID-19)
- The idiopathic classification suggests unknown causes may likely involve viral infections.### Bacterial and Autoimmune Causes of Pericarditis
- Tuberculosis is a significant bacterial cause of chronic pericarditis, potentially leading to constrictive pericarditis.
- Uremia arises in end-stage renal disease patients, with elevated urea levels causing pericardial inflammation.
- Autoimmune diseases, particularly systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), produce autoantibodies that may inflame the pericardium.
Post-Cardiac Injury Syndromes
- Post-myocardial infarction (MI) pericarditis can occur 1-3 days after MI (peri-infarction pericarditis) or 3-14 days later, termed Dressler syndrome, caused by autoantibodies.
- Pericarditis can also result from post-pericardiotomy syndromes following cardiac surgeries or traumatic injury to the pericardium.
Neoplastic Causes
- Several neoplasms can metastasize to the pericardium and cause inflammation, including lung cancer, lymphoma, renal cell carcinoma, and breast cancer.
- Radiation therapy for these cancers risks damaging nearby pericardial tissue, leading to inflammation.
Pericardial Effusions and Tamponade
- Pericardial effusion is defined as fluid accumulation in the pericardial cavity without causing tamponade physiology.
- Causes include infectious diseases, autoimmune diseases, uremia, post-MI conditions, and neoplasia.
- Purulent effusions can arise from significant bacterial infections such as tuberculosis, staphylococcus aureus, and streptococcus pneumoniae.
- Hemopericardium occurs when blood accumulates in the pericardial cavity due to events like aortic dissections or heart wall ruptures post-MI.
Differences Between Pericardial Effusion and Cardiac Tamponade
- Cardiac tamponade specifically refers to the compression of the heart due to significant fluid buildup that impairs filling during diastole.
- Tamponade physiology develops when pericardial pressures rise enough to restrict heart expansion, leading to decreased cardiac output and symptoms such as pulsus paradoxus.
Clinical Features of Acute Pericarditis
- Characteristic features include a pericardial friction rub and sharp, stabbing chest pain, worsened by taking a breath (pleuritic).
- Chest pain typically radiates to the trapezius ridge, is positional (less intense when sitting or leaning forward), and aggravated when lying down.
Clinical Features of Constrictive Pericarditis
- Presents with heart failure symptoms; commonly right-sided due to impaired filling of the right ventricle.
- Key signs include jugular venous distention, ascites, pedal edema, and exercise intolerance.
- Kussmaul's sign may be present, indicating elevated jugular venous pressure during inspiration due to impaired right ventricle filling.
Pericardial Knock
- A specific heart sound heard in constrictive pericarditis, related to sudden cessation of rapid ventricular filling due to a rigid pericardium.
Clinical Features of Cardiac Tamponade
- Characterized by Beck's triad: hypotension, muffled heart sounds, and jugular venous distention.
- Pulsus paradoxus: a drop in systolic blood pressure of more than 10 mmHg during inspiration, indicating significant impairment of heart filling.
- Symptoms may also include signs of obstructive shock due to compromised cardiac output.
Pathophysiology Summary
- Rapid fluid accumulation in the pericardial cavity leads to pressure that collapses the heart chambers, drastically reducing diastolic filling, and causing critical hemodynamic instability.### Cardiac Tamponade
- Pulsus paradoxus: A drop of more than 10 mmHg in blood pressure during inspiration, indicative of cardiac tamponade.
- Obstructive shock: Presenting signs include hypotension, reflexive tachycardia, and increased systemic vascular resistance to compensate for reduced cardiac output.
- High pressures in the right heart and distal veins can lead to distended inferior vena cava (IVC) and jugular veins.
- Measurement of right atrial and ventricular pressures via a Swan-Ganz catheter shows elevated pressures due to fluid in the pericardium.
- Left atrial pressure is similarly elevated, detectable through pulmonary capillary wedge pressure (≥18 mmHg), suggesting potential pulmonary edema.
Acute Pericarditis Diagnosis
- Four diagnostic criteria:
- Classic pleuritic chest pain: Sharp, substernal, radiating to the trapezius, worsens in supine position, and improves when leaning forward.
- Friction rub: A triphasic scratchy heart sound.
- ECG changes: Diffuse concave ST segment elevations across multiple leads, PR segment depression, and eventual T wave inversions.
- Evidence of new or worsening pericardial effusion identifiable via echocardiogram.
Constrictive Pericarditis Diagnosis
- Reduced ventricular filling due to a rigid pericardium leading to:
- Pericardial knock: A specific heart sound during early to mid-diastole due to rapid filling.
- Low QRS voltages on ECG indicating impaired electrical activity.
- Cardiac catheterization shows:
- Early diastolic filling evidenced by deep Y descent on jugular venous pressure (JVP) waveform.
- Square root sign correlating ventricular pressure curves, suggesting impeded expansion leading to rapid pressure rise.
- Presence of a septal bounce in echocardiograms due to shifting of the interventricular septum.
Treatment Overview
-
Acute Pericarditis:
- First-line: NSAIDs (ibuprofen, naproxen) to reduce inflammation.
- Corticosteroids: Considered second-line due to higher recurrence risks in certain cases.
- Colchicine: Shown to reduce recurrence and can be used alongside NSAIDs.
- Hospitalization is advised for patients with high fevers, large effusions, or worsening symptoms.
-
Constrictive Pericarditis:
- Manage heart failure symptoms by fluid and sodium restrictions.
- Diuretics may be utilized to alleviate volume overload.
- Pericardiectomy: Surgical removal of the rigid pericardium is the definitive treatment.
-
Pericardial Effusion:
- Pericardiocentesis: A needle-guided treatment to drain fluid, indicated in cases of high white count, fever, or suspected infection.
- Continuous drainage may be required in cases of recurrent effusions or malignancy via pericardial window.
-
Cardiac Tamponade:
- Immediate treatment includes pericardiocentesis to drain fluid.
- Supportive care may involve IV fluids and vasopressors to stabilize hemodynamics.
- Monitoring of intrathoracic pressure is crucial to optimize venous return and prevent cardiac arrest.

- Monitoring for hemodynamic variances is crucial to detect deteriorating pericardial effusions or development of tamponade.
Cardiac Tamponade and Obstructive Shock
- Pulsus paradoxus signifies blood pressure drops exceeding 10 mmHg with inspiration, indicative of cardiac tamponade.
- Presenting hypotension results from decreased venous return and ventricular filling; compensatory mechanisms may include tachycardia.
Diagnosing Acute Pericarditis
- Diagnosis necessitates fulfillment of four criteria: characteristic chest pain, pericardial friction rub, ECG changes, and a new or worsening pericardial effusion.
- ECG often exhibits diffuse ST segment elevations and PR segment depression.
Constrictive Pericarditis
- Characterized by restricted ventricular filling due to pericardial stiffness, resulting in heart failure.
- Clinical examination may reveal a pericardial knock and low QRS voltages on ECG.
Diagnostic Tools
- Echocardiography is essential for evaluating pericardial effusions and identifying constriction.
- CT or MRI can help visualize pericardial calcifications and thickening.
Treatment of Acute Pericarditis
- NSAIDs like ibuprofen and naproxen are first-line treatments alongside gastrointestinal protective agents.
- Corticosteroids may be used when NSAIDs are contraindicated, particularly in autoimmune cases, and colchicine may help prevent recurrences.
Treatment of Constrictive Pericarditis
- Management emphasizes alleviating right-sided heart failure through fluid restriction and potential diuretics.
- Surgical intervention via pericardiotomy is often required for irreversible cases.
Treatment of Pericardial Effusion
- Initial treatment involves pericardiocentesis for symptomatic relief and fluid analysis.
- Pericardial windows may be indicated for recurrent effusions to prevent re-accumulation.
Management of Cardiac Tamponade
- Acute stabilizing measures may involve IV fluids and vasopressors for hypotension.
- Definitive treatment typically includes pericardiocentesis; monitoring of fluid for underlying causes aids management decisions.
Key Clinical Findings
- Obstructive shock manifests through hypotension, tachycardia, and elevated central venous pressures, indicating potential tamponade.
- Characteristic ventricular pressure patterns, like the square root sign during diastole, suggest pericardial constraints.
Pericardial Diseases Overview
- Pericardial diseases encompass acute pericarditis, constrictive pericarditis, pericardial effusions, and cardiac tamponade.
- Acute pericarditis involves inflammation of the pericardium, while constrictive pericarditis is a chronic condition often resulting from repeated acute episodes.
Causes of Pericardial Diseases
- Common causes for both acute and constrictive pericarditis include infections, with idiopathic cases often stemming from unrecognized infections.
Key Infectious Viruses
- Coxsackie B virus is a significant viral cause of pericarditis.
- SARS-CoV-2 has emerged as a contributor to pericardial diseases during the COVID-19 pandemic.
Bacterial and Infectious Etiologies
- Tuberculosis is a leading cause of chronic and constrictive pericarditis.
- Uremia in end-stage renal disease can result in pericardial inflammation due to elevated urea.
- Autoimmune diseases like systemic lupus erythematosus (SLE) and rheumatoid arthritis can induce pericarditis through autoantibodies.
Post-Cardiac Injury Syndromes
- Post-myocardial infarction pericarditis can develop shortly after heart injury, with varying onset timing.
- Post-pericardiotomy syndrome arises following surgical heart interventions or traumatic injuries.
Neoplastic Causes
- Cancers such as lung, lymphoma, renal, and breast cancer can metastasize to the pericardium, causing disease.
- Radiation therapy affecting adjacent cancers may also lead to pericarditis.
Pericardial Effusions and Cardiac Tamponade
- Pericardial effusion refers to fluid build-up in the pericardial cavity, which does not always lead to cardiac tamponade.
- Causes range from infections and autoimmune disorders to malignancies and thoracic surgery complications.
- Hemopericardium can occur due to serious events such as aortic dissection or myocardial rupture.
Pathophysiology of Cardiac Tamponade
- Cardiac tamponade results from fluid accumulation that compresses the heart, affecting diastolic filling.
- Symptoms include Beck's triad: jugular venous distension (JVD), distant heart sounds, and hypotension due to reduced cardiac output.
Clinical Features of Pericarditis
- Acute pericarditis typically presents with sharp, pleuritic chest pain, aggravated by lying down and improved by sitting forward.
- A pericardial friction rub can be heard during specific cardiac phases.
Symptoms of Constrictive Pericarditis
- Right heart failure symptoms are prevalent in constrictive pericarditis, such as JVD, peripheral edema, and hepatic enlargement.
- Kussmaul's sign indicates elevated jugular venous pressure during inspiration, while a pericardial knock may be audible.
Management and Differential Diagnosis
- Cardiac tamponade may exhibit pulsus paradoxus, where systolic blood pressure decreases significantly during inhalation.
- Distinguishing between constrictive pericarditis and restrictive cardiomyopathy is clinically important, as symptoms can overlap.
Key Considerations
- Identifying the cause of pericarditis or effusion requires thorough clinical evaluation and diagnostic imaging.
- Monitoring for hemodynamic variances is crucial to detect deteriorating pericardial effusions or development of tamponade.
