Ehlers-Danlos Syndrome (EDS), Marfan Syndrome, Mineral Density
Conditions
Brief summary
The general objective of this research is to evaluate the characteristics of bone mineralisation in patients with Marfan syndrome or Ehlers-Danlos syndrome on a large case series. In particular we intend to obtain data regarding the characteristics of bone mineralisation, as well as their variation over time and the relationships existing with other clinical-anamnestic parameters, in patients with Marfan syndrome or Ehlers-Danlos syndrome by retrospectively analysing (data already collected for normal clinical practice and already available at the hospital) the case history of the Cardiovascular genetic center at IRCCS Policlinico San Donato and the related Computerized Bone Mineralometry (MOC) examinations performed at the Radiology Service of the same hospital between 1 September 2019 and 31 December 2022.
