A quadricuspid aortic valve that was mistakenly diagnosed as insidious
rheumatic carditis: A 13-year-old case.
Quaricuspid aortic valve (QAV) is a very rare congenital heart defect
characterized by the presence of four valves of the same or different
sizes. This anomaly may cause progressive aortic regurgitation or rarely
valve stenosis. The diagnosis of QAV may be difficult, misdiagnosed or
overlooked if careful evaluation is not made. Here, a 13-year-old
patient with QAV who presented to the outer center with a complaint of
chest weight, who was mistakenly diagnosed with insidious rheumatic
carditis due to aortic regurgitation, was presented, and and it was
aimed to draw attention to this rare congenital heart valve disease.
