Endomyocardial nodular calcification as a cause of heart failure.

Massive cardiac calcification is rare, occurring in association with chronic diseases or more commonly with previous myocardial infarction. We present an intriguing case of massive myocardial calcification of the left ventricle in a young patient with restrictive cardiomyopathy and progressive heart failure who required transplantation. The patient's history and clinical presentation did not reveal the etiology of the myocardial calcification.
