Rheumatoid Arthritis causes erosion of dens, atlanto-axial subluxation, inflammatory thickening of synovium called pannus, and these can compress the cord.
Sometimes accurate localization of the topographic landmarks is quite difficult because of an inferiorly hanging abdominal pannus. The abdominal pannus should be retracted superiorly to palpate the appropriate landmarks.
The pathogenesis of RA consist of a complex process involving Pannus formation ,synovial fibroblast proliferation causing infiltration of T-cells, B-cells, macrophages and plasma cells.
RA is associated with systemic and chronic inflammation of the joints, resulting in synovitis and pannus formation.
There is a hyperplasia of synovial cells, a lymphocytic infiltrate and a neoangiogenesis that lead to the formation of a proliferative and locally invasive tissue known as pannus that reaches the subchondral bone and the articular cartilage with progressive destruction (Harris Jr, 1997; Jimenez-Boj et al, 2007).
At the interface of the synovium, cartilage and bone, pannus tissue is formed, which contributes to bone destruction.
After left atriotomy, mitral valve exploration revealed severe pannus tissue and thrombi on both sides of mechanical valve's hinge area and sewing cuff (Figure 1).

Mechanical prosthetic heart valve MHV obstruction may be caused by thrombus formation, pannus in-growth, or a combination of both3.
The extent of synovial inflammation and bone/cartilage destruction was determined using a 0~4 scale (0 = normal synovium, 1 = synovial membrane hypertrophy and cell infiltrates, 2 = pannus and cartilage erosion, 3 = major erosion of cartilage and subchondral bone, and 4 = loss of joint integrity and ankylosis) according to the previous study [16].
It is thought that the breakdown of immune tolerance triggered by environmental stimuli in genetically susceptible individuals leads to synovial inflammation and hypertrophy, pannus formation, neoangiogenesis, and subsequent degradation of adjacent cartilages and bones in RA [1].
