Spontaneous coronary artery dissection and aortic dilatation presenting concomitantly: a case report.

INTRODUCTION

Spontaneous coronary artery dissection (SCAD) is defined as a non-traumatic, non-iatrogenic, non-atherosclerotic separation of the coronary arterial walls, creating a false lumen. The space created is filled with an intramural haematoma (IMH) that compresses the true arterial lumen, decreasing anterograde blood flow. Spontaneous coronary artery dissection is commonly associated with small and medium sized extracoronary vascular abnormalities.

CASE PRESENTATION

This case report describes a case of SCAD presenting as an acute coronary syndrome together with aortic dilatation requiring aortic valve and aortic root replacement.

DISCUSSION

Despite the fact that SCAD and aortic dilatation share common aetiologies, this is the first case to our knowledge describing severe aortic dilatation and SCAD presenting concomitantly. This case highlights the importance of confirming the diagnosis of SCAD with intravascular imaging and of investigating for extracoronary arteriopathies.
