Earliest valvular lesion in a case of acute rheumatic fever is –
Mitral regurgitation (MR)
Aortic Regurgitation(AR)
Mitral stenosis (MS)
Aortic Stenosis (AS)
In rheumatic fever valvular abnormalities usually are associated with chronic disease but mitral regurgitation is seen in acute rheumatic fever.
Mitral regurgitation is the commonest manifestation of acute as well as previous rheumatic carditis.
