Study Notes
-
- The pericardium is a double-layered membrane that surrounds the heart
- It protects the heart, reduces friction, and limits over-expansion
- Pericardial conditions affect heart function and circulation
Pericardium Anatomy
- The pericardium is a double-walled sac that protects the heart
- It provides lubrication and prevent excessive movement
- The pericardium consists of two main layers: the fibrous pericardium and the serous pericardium
- The fibrous pericardium is the outer layer and made of tough, inelastic connective tissue
- It anchors the heart to the diaphragm and sternum
- Prevents overdistension of the heart
- The serous pericardium is the inner layer being a thin, double-layered membrane
- The serous pericardium is composed of the parietal and visceral layers
- The parietal Layer lines the inside of the fibrous pericardium
- The visceral Layer (Epicardium) adheres directly to the surface of the heart
- The pericardial cavity is the space between the parietal and visceral layers of the serous pericardium
- The pericardial cavity contains pericardial fluid
- The pericardial fluid reduces friction during heart contractions
Pericarditis Pathophysiology
- Inflammation leads to increased capillary permeability
- Fluid, proteins, and inflammatory cells infiltrate the pericardium
- Fibrinous deposits and pericardial thickening may occur
- Chronic cases may lead to constrictive pericarditis
Pericarditis Risk Factors
- Recent viral or bacterial infections
- Autoimmune diseases, such as lupus and rheumatoid arthritis
- Myocardial infarction (Dressler's syndrome)
- Cancer and radiation therapy
- Uremia (kidney failure)
- Post-cardiac surgery
Symptoms of Pericarditis
- Sharp, pleuritic chest pain (worse with inspiration or lying down)
- Pericardial friction rub (scratchy heart sound)
- Fever and malaise
- Dyspnea (shortness of breath)
Diagnosis of Pericarditis
- ECG shows ST-segment elevations, PR depressions
- Echocardiogram detects pericardial effusion
- Chest X-ray shows cardiomegaly if significant effusion is present
- Blood tests reveal elevated CRP, ESR, WBCs; troponins may be elevated
- Pericardiocentesis if effusion is large or recurrent
Pharmacological Treatment of Pericarditis
- NSAIDs (e.g., ibuprofen, aspirin): Considered first-line treatment
- Colchicine: Prevents recurrence
- Corticosteroids: Reserved for refractory cases
- Antibiotics: Used if bacterial infection is suspected
- Antiviral agents: Used if viral etiology is suspected
Nursing Considerations for Pericarditis
- Monitor vital signs, especially heart rate and blood pressure
- Assess for worsening effusion or tamponade, indicated by muffled heart sounds and hypotension
- Provide pain management and patient positioning, such as an upright position to relieve pain
- Educate the patient on medication adherence and follow-up care
- Encourage rest and hydration
Pericardial Effusion Pathophysiology
- Increased pericardial fluid accumulation from inflammation, infection, or malignancy
- Can be transudative (systemic causes) or exudative (infection, malignancy)
- May progress to tamponade if fluid accumulation is rapid
Pericardial Effusion Risk Factors
- Cancer (metastatic involvement)
- Chronic pericarditis
- Autoimmune diseases
- Kidney failure (uremic pericarditis)
- Post-cardiac surgery or trauma
Symptoms of Pericardial Effusion
- Can be asymptomatic if slow accumulation
- Dyspnea and orthopnea (difficulty breathing when lying down)
- Chest discomfort or fullness
- Muffled heart sounds
Diagnosis of Pericardial Effusion
- Echocardiogram is the gold standard for detecting effusion
- Chest X-ray shows enlarged cardiac silhouette ("water bottle heart")
- ECG shows electrical alternans (varying QRS amplitude)
- Pericardiocentesis is performed for fluid analysis to determine etiology
Pharmacological Treatment of Pericardial Effusion
- Diuretics are used to reduce fluid overload in transudative effusions
- Anti-inflammatory drugs include NSAIDs and colchicine for inflammatory causes
- Antibiotics/antifungals are used if infectious cause is suspected
- Chemotherapy or immunotherapy are used if malignancy is related
Considerations for Pericardial Effusion
- Monitor for signs of cardiac tamponade, such as hypotension, jugular venous distension, and pulsus paradoxus
- Assist with pericardiocentesis if required
- Educate the patient on disease progression and follow-up imaging
- Assess for complications (infection, bleeding)
Cardiac Tamponade Pathophysiology
- Rapid fluid accumulation increases intrapericardial pressure
- Compression of heart chambers reduces ventricular filling
- Decreased cardiac output leads to hypotension and shock
Cardiac Tamponade Risk Factors
- Rapid accumulation of pericardial effusion (trauma, malignancy, rupture of aneurysm)
- Post-surgical complications
- Severe infections or pericarditis
Symptoms of Cardiac Tamponade
- Beck's Triad consists of hypotension, muffled heart sounds, and jugular venous distention
- Tachycardia, weak pulse (pulsus paradoxus)
- Dyspnea, confusion, and agitation
Diagnosis of Cardiac Tamponade
- Echocardiogram shows chamber collapse and excessive pericardial fluid
- ECG shows electrical alternans
- Hemodynamic monitoring reveals increased central venous pressure
Management of Cardiac Tamponade
- Emergency pericardiocentesis involves needle aspiration of pericardial fluid
- Surgical pericardial window is performed if recurrent effusion occurs
- Intravenous fluids are administered to maintain preload
- Vasopressors support blood pressure in hypotensive patients
- Underlying causes are treated with antibiotics, anti-inflammatories, or cancer treatment
Nursing Considerations for Cardiac Tamponade
- Monitor for rapid deterioration and signs of shock
- Prepare for emergency pericardiocentesis or surgical intervention
- Ensure continuous cardiac monitoring
- Educate the patient and family about symptoms requiring emergency care
Pericardiocentesis
-
A procedure where extra fluid is drained from around the heart
-
Often used for life-threatening conditions
-
Involves inserting a needle into the chest until it reaches the pericardium
-
Once there, the needle can drain fluid directly or place a drain to remove fluid over time
-
Used to treat pericardial effusion (too much fluid in the pericardium)
-
Pericardial effusions can lead to cardiac tamponade which is a medical emergency with deadly results in minutes to hours
-
A provider can use pericardiocentesis as an emergency or not. In emergencies they treat either cardiac tamponade or severe pericardial effusions that will cause cardiac tamponade
-
In non-emergencies they can dettermine what is causing this
