Abstract
We report an unusual case of heart failure due to massive myocardial calcification related to a rare combination of idiopathic mitral annular calcification, myocardial calcification of the left ventricular septum and the inferior wall without other predisposing factors, such as previous myocardial infarction, ventricular aneurysms, myocarditis, rheumatic heart disease, tuberculosis, chronic renal failure, or systemic metabolic disease (sarcoidosis or primary hyperoxaluria). The related restrictive pattern of diastolic filling of the left ventricle could explain this unusual case of heart failure with preserved ejection fraction. .
