Myocardial infarction induced by caseous mitral annular calcification: a case report.

ABSTRACT:

Background

Caseous mitral annular calcification (CMAC) is a rare variant of mitral annular calcification. Symptoms can be related to mitral valvular dysfunction, arterial embolization, and transient aortic outflow tract obstruction. CMAC usually affects the posterior fibrous mitral annulus and is commonly diagnosed in elderly patients with a history of hypertension, dyslipidaemia, and renal failure.

Case summary

A 68-year-old patient was transferred to our department for late presenting acute myocardial infarction and acute heart failure. Coronary angiography revealed a significant extrinsic compression of the circumflex artery. Transthoracic echocardiography revealed an ovoid calcified mass of 3.6 cm × 2 cm originating from the posterior mitral annulus causing moderate mitr
