Idiopathic arterial calcification in infancy

Abstract

Two cases of idiopathic arterial calcification in babies, with predominant involvement of the coronary arteries, are described. The aetiology of the condition is unknown, but we suggest that calcification may occur primarily in muscle fibres rather than in the elastica and that the clinical features result from vascular occlusion dependent upon subintimal fibrosis rather than medial calcification.
