Dear Andrea,
our Center of reference for HHT (Maggiore Hospital , Crema , Italy) belongs to VASC-ERN, and I am co-chair of the VASCERN-HHT group. So , one more Valdig member in the ERN. I would be more than happy to foster collaboration between VALDIG and VASC-ERN if you feel appropriate.
All my best !
Elisa
