(IN THE CLINIC: Pericarditis)
What is pericarditis?
An inflammatory condition of the pericardium.
(IN THE CLINIC: Pericarditis)
What can cause pericarditis?
Common causes are:
- viral infections
- bacterial infections
- systemic illnesses (e.g., chronic renal failure)
- after myocardial infarction
(IN THE CLINIC: Pericarditis)
Why must pericarditis be distinguished from myocardial infarction?
Because the treatment and prognosis are quite different.
(IN THE CLINIC: Pericarditis)
What are symptoms of pericarditis?
As in patients with myocardial infarction, patients with pericarditis complain of “continuous central chest pain that may radiate to one or both arms”.
(IN THE CLINIC: Pericarditis)
How can pain from pericarditis be relieved?
By sitting forward
(IN THE CLINIC: Pericarditis)
What is a differential between myocardial infarction and pericarditis?
Unlike myocardial infarction, the pain from pericarditis may be relieved by sitting forward.
(IN THE CLINIC: Pericarditis)
What can be done to help differentiate between pericarditis and MI?
An electrocardiogram (ECG).
(IN THE CLINIC: Pericardial effusion)
How much fluid is normally present between the visceral and parietal layers of the serous pericardium?
Normally, only a tiny amount of fluid
(IN THE CLINIC: Pericardial effusion)
What is a pericardial effusion?
When in certain situations, the pericardial cavity is filled with excess fluid.
(IN THE CLINIC: Pericardial effusion)
What can pericardial effusion lead to?
Cardiac tamponade
(IN THE CLINIC: Pericardial effusion)
Why can pericardial effusion lead to cardiac tamponade?
Because the fibrous pericardium is a “relatively fixed” structure that cannot expand easily, a rapid accumulation of excess fluid within the pericardial sac compresses the heart (cardiac tamponade), resulting in biventricular failure.
(IN THE CLINIC: Pericardial effusion)
What is cardiac tamponade?
Excess fluid within the pericardial sac compressing the heart
(IN THE CLINIC: Pericardial effusion)
What can cardiac tamponade lead to?
Biventricular failure
(IN THE CLINIC: Pericardial effusion)
How can we treat pericardial effusions?
Removing the fluid with a needle inserted into the pericardial sac can relieve the symptoms.
(IN THE CLINIC: Constrictive pericarditis)
What is constrictive pericarditis?
Abnormal thickening of the pericardial sac
(IN THE CLINIC: Constrictive pericarditis)
What can happen in constrictive pericarditis?
Abnormal thickening of the pericardial sac can compress the heart, impairing heart function and resulting in heart failure.
(IN THE CLINIC: Constrictive pericarditis)
How is constrictive pericarditis diagnosed?
By inspecting the jugular venous pulse in the neck.
(IN THE CLINIC: Constrictive pericarditis)
What happens to the JVP in normal individuals?
It drops on inspiration
(IN THE CLINIC: Constrictive pericarditis)
What happens to the JVP in patients with constrictive pericarditis?
In normal individuals, the JVP drops on inspiration. In patients with constrictive pericarditis, the reverse happens (Kussmaul’s sign).
(IN THE CLINIC: Constrictive pericarditis)
What is Kussmaul’s sign?
A paradoxical rise in JVP on inspiration (it should normally drop), or a failure in the appropriate fall on inspiration.
(IN THE CLINIC: Constrictive pericarditis)
What is a differential of constrictive pericarditis?
JVP on inspiration (Kussmaul’s sign)
(IN THE CLINIC: Constrictive pericarditis)
What is Kussmaul’s sign indicative of?
It is normally the differential associated with constrictive pericarditis.
It is usually indicative of limited right ventricular filling due to right heart dysfunction.
(IN THE CLINIC: Constrictive pericarditis)
How is constrictive pericarditis normally treated?
Treatment often involves surgical opening of the pericardial sac.

What does the term ‘incompetence’ mean in relation to valve problems?
Insufficiency
(IN THE CLINIC: Valve disease)
What does incompetence (insufficiency) of valve problems arise from?
Incompetence, which results from poorly functioning valves
(IN THE CLINIC: Valve disease)
What is stenosis of a valve?
A narrowing of the orifice
(IN THE CLINIC: Valve disease)
What causes stenosis of a valve?
Stenosis, a narrowing of the orifice, caused by the valve’s inability to open fully.
(IN THE CLINIC: Valve disease)
What valve problem is present in mitral valve disease?
MITRAL VALVE DISEASE is usually a mixed pattern of stenosis and incompetence, one of which usually predominates.
(IN THE CLINIC: Valve disease)
What do stenosis and incompetence of a valve lead to?
A poorly functioning valve and subsequent heart changes
(IN THE CLINIC: Valve disease)
What heart changes occur in mitral valve disease?
- Left ventricular hypertrophy
- Increased pulmonary venous pressure
- Pulmonary oedema
- Enlargement (dilation) and hypertrophy of the left atrium
(IN THE CLINIC: Valve disease)
What happens to the left ventricle in mitral valve disease?
Left ventricular hypertrophy (this is appreciably less marked in patients with mitral stenosis)
(IN THE CLINIC: Valve disease)
What happens to the left atrium in mitral valve disease?
Enlargement (dilation) and hypertrophy
(IN THE CLINIC: Valve disease)
What happens to the pulmonary venous pressure in mitral valve disease?
Increases
(IN THE CLINIC: Valve disease)
What is pulmonary oedema?
Fluid accumulation in the tissue and air spaces of the lungs
(IN THE CLINIC: Valve disease)
What is mitral valve disease?
When the mitral valve does not close properly, leading to regurgitation (blood flowing back to the left atrium) or stenosis (valve narrowing).
(IN THE CLINIC: Valve disease)
What are two types of aortic valve disease?
- Aortic stenosis
- Aortic regurgitation (backflow)
(IN THE CLINIC: Valve disease)
What can aortic valve disease produce?
Both aortic stenosis and aortic regurgitation (backflow) can produce marked heart failure.
(IN THE CLINIC: Valve disease)
What does valve disease in the right side of the heart affect?
The tricuspid or pulmonary valve
(IN THE CLINIC: Valve disease)
What is valve disease in the right side of the heart most likely caused by?
Infection
(IN THE CLINIC: Valve disease)
What does valve disease in the right side mean for the heart?
The resulting valve dysfunction produces abnormal pressure changes in the right atrium and right ventricle
(IN THE CLINIC: Valve disease)
What can valve disease in the right side of the heart induce?
Cardiac failure
