Marfan Syndrome Presenting as Spontaneous Coronary Artery Dissection and Arteriopathy.

INTRODUCTION

Spontaneous coronary artery dissection (SCAD) is a term used to define a spontaneous separation of the coronary artery wall not related to underlying risk factors, such as trauma or underlying atherosclerotic disease. While SCAD has a range of different etiologies, with fibromuscular dysplasia being the most common, most cases of SCAD have no concomitant arteriopathy.

CASE REPORT: Here we describe a case of a patient who presented to our institution with SCAD and evidence of an asymptomatic arteriopathy involving extracranial segments of the carotid and vertebral arteries, later found to have a pathogenic variant in the FBN1 gene and ultimately diagnosed with Marfan syndrome. This has only been rarely described in the literature as an etiology for SCAD.

CONCLUSION

Although rare, it is important to consider underlying connective tissue disorders in patients presenting with spontaneous coronary artery dissection and arteriopathy without underlying cardiovascular risk factors.
