Aortic regurgitation in rheumatoid arthritis necessitating aortic valve replacement.

Four cases of patients with aortic incompetence secondary to rheumatoid arthritis are presented. All survived aortic surgery (two having bioprosthetic aortic valve replacement and two a homograft aortic root replacement). A review of the pathophysiology and pathology of this rare cause of aortic regurgitation is presented. A rationale for the choice of aortic valve prosthesis is discussed.
