Pregnancy in Women With Rare Multisystemic Vascular Diseases: COGRare5 Study

There are no prospective studies of pregnancies for the diseases studied here in (Heredity Hemorrhagic Telangiectasia, Marfan syndrome or related, primary lower limb lymphedema, superficial arteriovenous malformations, and cerebro-spinal arteriovenous malformations) although complications of these can present life-threatening health problems for the mother and her baby. The purpose of this National prospective study is to obtain greater insight into obstetrical complications associated with rare maternal vascular genetic disorders in order to improve prevention and to reduce risk of death. In this context, experts and patient associations consider that there is a need to make real progress in the formulation of recommendations based on scientific data.

Imaging Lymphatic Function in Normal Subjects and in Persons With Lymphatic Disorders

The purpose of this study is to demonstrate the feasibility of near-infrared fluorescence imaging in subjects with acquired or hereditary lymphedema, in subjects with lipidema and other lymphovascular disorders and in normal health subjects; in order to attempt to correlate imaging phenotype(s) with genotype(s).

A Trial of Targeted Therapies for Patients With Slow-Flow or Fast-Flow Vascular Malformations

Recent studies have demonstrated that growth of vascular malformations can be driven by genetic variants in one of 2 signalling pathways. Targeted drugs specific to these pathways have been developed and shown to be effective in treating cancer. This study will describe the effectiveness of (i) 48 weeks of alpelisib therapy for participants with slow-flow vascular malformations and a gene mutation in one of these signalling pathways (module 1) and (ii) 48 weeks of mirdametinib therapy for participants with fast-flow vascular malformations and a gene mutations in the other signalling pathway (module 2).

Identification of Biomarkers for Patients with Vascular Anomalies

The study will use blood (serum and plasma) and tissue obtained from participants undergoing prescribed surgical resection of vascular anomalies of interest proposed in this study. The study will also use blood (serum and plasma) and tissue collected and stored in a tissue bank maintained by the Department of Hematology/Oncology.

A 10-Minute Cardiovascular Magnetic Resonance Protocol for Cardiac Disease

This study aims to identify and assess new CMR techniques that can improve current CMR protocols.
