One possible side-effect of mitral valve prolapse (MVP) in someone with polycystic kidney disease (PKD) is an increased risk of developing infective endocarditis, a potentially serious infection of the heart valve. This is because MVP can cause the valve to become weakened or damaged, making it more susceptible to infection. It is important for individuals with MVP and PKD to be vigilant about their heart health and to consult with a healthcare provider for appropriate monitoring and management.
