Multiple calcific embolism following mtral valvotomy.

Calcification of the valve is frequently encountered at valvotomy for the relief of mitral stenosis. Calcific embolism is a recognized hazard of the operation, but Michell (1960), who has reviewed the problem of valvular calcification with regard to mitral valvotomy, has stated that, "the danger from calcific emboli during valvotomy does not seem to be very great." Perhaps it is not always recognized, even at necropsy. The purpose of this paper is to report a case of multiple calcific embolism following mitral valvotomy, and to describe the methods used for the detection of these emboli.
