Recently, several publications have confirmed the association between pergolide use and valvular heart disease (VHD).1–3 The serotonin 2B (5HT2b) receptor has been proposed as the key pathway through which pergolide and other drugs activate valvular fibroblasts to proliferate and to produce myxoid substance and collagen, leading to valvular thickening and insufficiency.4 This can explain the occurrence of VHD with 5HT2b agonists such as pergolide and cabergoline, while drugs without 5HT2b activity have not been reported to cause valvulopathy (i.e. pramipexole, lisuride).
