“The connective tissue clinic at CHEO accepts referrals for patients with suspected underlying heritable connective tissue disorders. We aim to diagnose and care for patients and families with Loeys-Dietz syndrome, Marfan syndrome, vascular EDS and other forms of familial thoracic aneurysms. We also see patients without a family history if they present with a significant aortic dilation before 50 years of age or if they sustained a spontaneous arterial dissection prior to age 50 in the absence of another identified etiology. Finally, we see patients with significant joint hypermobility in the presence of additional findings.  Care is provided in close collaboration with the team from the Aorta Clinic of the Ottawa Heart Institute for our adult patients and with Dr. Lai and other pediatric cardiologists for our pediatric patients.” 
The clinic is open to individuals of all ages, despite it being housed in a paediatric hospital.
