Pericarditis and pericardial disease

Pericarditis is an inflammation of the Pericardium. The pericardium is the fibrous sheath around the heart. About 20% of myocardial infarction patients develop pericarditis.

Atrial fibrillation (AF)

Atrial fibrillation (AF) is a disorder of the rhythm of the heart. It results from disorganised electrical activity in the atria of the heart, which causes rapid stimulation of the ventricles, leading to an irregular pulse rate. AF is the most common sustained cardiac arrhythmia.

Aortic stenosis (AS)

Aortic stenosis (AS) is the constriction of the aortic valve of the heart - the valve that regulates the blood being pumped out by the heart and stops it from flowing back into the left ventricle of heart. Aortic stenosis leads to heart failure.

Aortic regurgitation (AR)

Aortic regurgitation is reflux of blood from the aorta (the big vessel carrying blood out of the heart). The problem occurs when some of the blood pumped out falls back into the heart, because of an incompetent aortic valve which would normally stop this from happening.

Infective endocarditis (IE)

Information on the symptoms, treatment and diagnosis of Infective endocarditis by professional health specialists.

Mitral regurgitation (MR)

Acute mitral regurgitation is a disorder in which the heart's mitral valve (between the left aftrium and left ventricle) does not close properly, causing blood to leak (back-flow) into the left atrium (upper heart chamber) when the left ventricle (lower heart chamber) contracts.

Mitral stenosis (MS)

Mitral stenosis is a narrowing or obstruction of the opening of the mitral valve, which separates the upper (left arium) and lower chamber (left ventricle) on the left side of the heart. This prevents adequate blood flow between the left atrium (upper chamber) and ventricle...
