Acute on chronic severe aortic insufficiency due to rheumatoid arthritis-associated valvulitis

摘要

Rheumatoid Arthritis associated valvular heart disease (RA-VHD) may occur in patients in varying degrees of severity. Aortic valve involvement leading to severe symptomatic aortic insufficiency is a rare complication of rheumatoid arthritis. This entity has not been well characterized and its clinical predictors are undefined. The pathology of RA-VHD can extend from benign nodular development to acute valvulitis with late-stage leaflet fibrosis and severe valvular regurgitation. In this report, we describe a rare case of acute heart failure (AHF) resulting from severe aortic valve destruction and insufficiency due to persistent chronic inflammation in a patient with long-standing RA. Persistent systemic inflammation of RA involved the aortic valve causing nodular thickening and leaflet destruction. Our patient had compensated chronic heart failure due to progressive aortic insufficiency resulting from gradual leaflet destruction. However, she suddenly developed AHF requiring valve replacement. Her clinical presentation, gross and histological images suggest an acute/subacute disruption of the friable aortic leaflets that resulted in AHF.
