An echocardiogram has the ability to detect signs of RHD before the development of more obvious symptoms such as tissue scarring and stenosis. [31] Modified Jones criteria were first published in 1944 by T. Duckett Jones , MD. [ 32 ]
Right hemisphere brain damage (RHD) is the result of injury to the right cerebral hemisphere. [1] The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. [ 1 ]
Valvular heart disease resulting from rheumatic fever is referred to as rheumatic heart disease. Acute rheumatic fever, which frequently manifests with carditis and valvulitis, [ 20 ] is a late sequela of Group A beta-hemolytic streptococcus infection in the throat, often lagging the initial infection by weeks to months.

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.
Two cross-reactive streptococcal antigens have been identified, the M protein and N-acetyl-beta-D-glucosamine, whereby infection leads to autoantibodies being produced against host tissues (molecular mimicry) causing a variety of streptococcal related diseases including Sydenham's chorea but also rheumatic heart disease and nephritic syndrome.

Signs and symptoms of mitral stenosis include the following: Heart failure symptoms, such as dyspnea on exertion, orthopnea and paroxysmal nocturnal dyspnea (PND) [3] Palpitations [3] Chest pain [3] Hemoptysis [3] Thromboembolism [3] in later stages when the left atrial volume is increased (i.e., dilation).
In an Indian hospital between 2004 and 2005, 4 of 24 endocarditis patients failed to demonstrate classic vegetations. All had rheumatic heart disease (RHD) and presented with prolonged fever. All had severe eccentric mitral regurgitation (MR). (One had severe aortic regurgitation (AR) also.) One had flail posterior mitral leaflet (PML). [34]
The following tests may also show signs of rheumatoid lung disease: [7] Chest x-ray may show: pleural effusion; lower zone predominant reticular or reticulonodular pattern; volume loss in advanced disease; skeletal changes, e.g. erosion of clavicles, glenohumeral erosive arthropathy, superior rib notching; Chest CT or HRCT features include:
