Left atrial leiomyosarcoma: A rare cause of mitral valve (pseudo)stenosis

Abstract

A 54-year-old lady presented with a mass in the left atrium causing an acute mitral valve pseudo-stenosis. The tumour mass was assumed to be a myxoma.

The patient was scheduled for tumour mass extirpation to clear the obstruction of the mitral orifice. Histological finding from the acquired specimen showed a leiomyosarcoma, as a rare primary malignant cardiac tumour.
