The revised Jones criteria are guidelines decided on by the American Heart Association to help doctors diagnose rheumatic fever. Two major criteria or one major and two minor criteria plus laboratory evidence of a preceding group A streptococcal (GAS) infection are required to make the diagnosis of rheumatic fever.

What are the features of acute rheumatic carditis?

Patients with carditis may present with shortness of breath, dyspnea upon exertion, cough, paroxysmal nocturnal dyspnea, chest pain, and/or orthopnea. Carditis may also be asymptomatic and may be diagnosed solely via auscultation or echocardiography.

What is cause of rheumatic fever?

Rheumatic fever can occur after a throat infection from a bacteria called group A streptococcus. Group A streptococcus infections of the throat cause strep throat or, less commonly, scarlet fever. Group A streptococcus infections of the skin or other parts of the body rarely trigger rheumatic fever.

Which valves are commonly affected by RF?

The valves most affected by rheumatic fever, in order, are the mitral, aortic, tricuspid, and pulmonary valves. In most cases, the mitral valve is involved with 1 or more of the other 3. In acute disease, small thrombi form along the lines of valve closure.

What is the most common clinical cardiac abnormality that is associated with acute rheumatic heart disease?

Rheumatic heart disease chronically manifests as congestive heart failure from valvular involvement. Most commonly the mitral valve is affected, resulting in mitral stenosis or mitral regurgitation. Less commonly, the aortic valve can be involved; tricuspid valve involvement is rare, but reported.

What are the three types of Carditis?

CARDITIS

• PERICARDITIS. Pericarditis, inflammation of the fibroserous sac enclosing the heart, manifests itself as one of three types as a result of the bodies reaction to the infecting agent:
• MYOCARDITIS. ETIOLOGICAL AGENTS:
• ENDOCARDITIS.
• MYOCARDIAL INFARCTION.

What is milkmaid grip?

A common symptom is “milkmaid’s grip.” People with this condition don’t have coordinated hand muscles and will squeeze and release their hand, as if milking. Another symptom is involuntarily sticking out the tongue. Chorea movements can be fast or slow.

What are the Jones criteria for moderate- and high-risk populations?

Revised Jones criteria, moderate- and high-risk populations: Major and minor criteria are as follows: Major criteria: carditis (clinical and/or subclinical), arthritis (monopolyarthritis or polyarthritis, or polyarthralgia), chorea, Erythema marginatum, and subcutaneous nodules. Minor criteria: fever (≥38.5° F),

Is there a role for echocardiography in the Jones criteria?

However, in the past few years, developments in several areas have prompted reexamination of the traditional Jones criteria. For example, the limited diagnostic role for echocardiography in the diagnosis of carditis as expressed in the Jones criteria revision of 1992 2 is a major area of focus.

When did the American Heart Association change the Jones criteria?

This effort has resulted in the first substantial revision to the Jones criteria by the American Heart Association since 1992 and the first application of the Classification of Recommendations and Levels of Evidence categories developed by the American College of Cardiology/American Heart Association to the Jones criteria.

What are the Jones criteria for carditis as a manifestation of ARF?

Classically, as discussed in the 1992 AHA revised Jones criteria statement, carditis as a major manifestation of ARF has been a clinical diagnosis based on the auscultation of typical murmurs that indicate mitral or aortic valve regurgitation, at either valve or both valves.
