What this trial studies

This initiative aims to gather and analyze data on Fibromuscular Dysplasia (FMD) and related conditions globally. It will document demographic and arterial characteristics, evaluate the incidence of new FMD lesions, and investigate genetic and molecular mechanisms associated with the disease. Participants will provide clinical data retrospectively and prospectively, with an option to contribute to a biobank for further research. The study seeks to enhance understanding of FMD and its implications for patient care.

Who should consider this trial

Good fit: Ideal candidates include patients with established FMD, those with Spontaneous Coronary Artery Dissection (SCAD) showing FMD lesions, and individuals with atypical FMD presentations.

Not a fit: Patients whose diagnosis is based solely on ultrasound without confirmation from advanced imaging techniques will not benefit from this study.

Why it matters

Potential benefit: If successful, this initiative could lead to improved diagnosis, treatment, and management of Fibromuscular Dysplasia.

How similar studies have performed: Other studies have shown promise in understanding FMD through genetic and clinical data collection, making this initiative a continuation of established research efforts.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

(i) Patients with established FMD, i.e at least one string-of-beads (multifocal FMD) or focal stenosis (focal FMD).

(ii) Patients with Spontaneous Coronary Artery Dissection (SCAD) in whom at least one lesion of multifocal FMD (string-of beads) in extra-coronary arteries has been identified ("SCAD-FMD").

(iii) Patients with so-called "atypical FMD" or "FMD-like presentation", i.e. patients presenting with at least one dissection or 2 aneurysms \< 60-year-old, in the absence string-of-beads, focal stenosis or evidence of inherited arteriopathy.

Exclusion Criteria:

Diagnosis based only on ultrasound (need for computed tomographic angiography , magnetic resonance angiography or catheter-based angiography to confirm the diagnosis)
