Coronary fibromuscular dysplasia with three-vessel involvement: a rare cause of ischaemic dilated cardiomyopathy in a very young male.

Coronary artery disease of non-atherosclerotic aetiology, while rare in incidence, can have a wide aetiology, such as fibromuscular dysplasia, which is a non-inflammatory arteriopathy of numerous histopathological types of fibromuscular tissue accumulation. This brief report describes the case of a 22-year-old male with a recently developed dilated cardiomyopathy and a history of aborted cardiac arrest at the age of 14 years. Coronary angiogram revealed severe three vessels disease, while optical coherence tomography established fibromuscular dysplasia as aetiology. Balloon and stent angioplasty was performed guided by fractional flow reserve with acceptable angiographic result.
