Caseous calcification of the mitral annulus associated with a complete atrioventricular block: a case report.

ABSTRACT:

Background

Caseous calcification of the mitral annulus (CCMA), a subtype of mitral annulus calcification, is rarely encountered. Although most cases of CCMA are asymptomatic and have a benign course, there are several reports of mitral valve dysfunction, stroke, and myocardial infarction. However, few reports have been published on conduction disturbances.

Case summary

We encountered a case of an atrioventricular block, which is a rarely reported complication, in a 70-year-old woman who presented with heart failure. The patient's anatomy suggested a conduction disturbance caused by CCMA extending from the posterior apex of the mitral annulus to the ventricular septum. Our heart team discussed whether surgical resection should be performed. We concluded that bradycardia was t
