A pericardial cyst is an uncommon benign dilatation of the pericardial sac surrounding the heart. It can lead to symptoms by compressing nearby structures, but is usually asymptomatic. [1] Pericardial cysts can be congenital or acquired, and they are typically diagnosed with radiologic imaging.
SCAD symptoms are the result of a restriction in the size of the lumen of the affected coronary artery. A bleed within the wall of the artery ( tunica intima ) originating from the microvessels that perfuse this muscular layer ( vasa vasorum ) leads to a collection of blood, or hematoma , between the layers of the artery wall.

Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
For others, if the enlarged heart begins to affect the body's ability to pump blood, then symptoms associated with congestive heart failure may arise, including: [15] Heart palpitations – the irregular beating of the heart, usually associated with a valve; Severe shortness of breath (especially when physically active) Chest pain
Histologically, sarcoidosis of the heart is an active granulomatous inflammation surrounded by reactive oedema. The distribution of affected areas is patchy with localised enlargement of heart muscles. This causes scarring and remodelling of the heart, which leads to dilatation of heart cavities and thinning of heart muscles.
Often, symptoms mimic those of congestive heart failure (esp. activity intolerance and dyspnea), but treatment of each is different. Beta blockers are used in both cases, but treatment with diuretics, a mainstay of CHF treatment, will exacerbate symptoms in hypertrophic obstructive cardiomyopathy by decreasing ventricular preload volume and ...
Cardiac Histiocytes / Anitschkow are present in small numbers in the heart but their numbers are increased in Aschoff nodules. therefore they are not characteristic of rheumatic heart disease. Stage 3. Late fibrosis stage. It is the stage of healing by which the fibrosis of the Aschoff nodules occur in 12 to 16 weeks after the illness.
Certain diseases such as neuroendocrine tumor of the small intestine (also known by the obsolete term carcinoid), which sometimes release large amounts of 5-hydroxytryptamine, commonly known as 5-HT or serotonin into the blood, may produce a characteristic pattern of mostly right-sided cardiac fibrosis which can be identified with echocardiography.
