Fibrotic valvular heart diseases are known as rare complications of long-time therapy of Parkinson's disease with ergot-derivatives including some ergot-dopamine agonists. The aim of this study is to assess the incidence of valvular heart disease, which may be an ergot-drug agonists side-effect or an overall complication of all dopamine agonists. Incidence, prevalence and addiction of dose or intake duration are not known so far. The reversibility of the changes is unknown too. To answer these questions the present study is designed as a cross sectional study followed by a 2 year follow-up prospective cohort study.
