摘要

A 41 -year-old woman suffering from chest pain underwent successful resection of a right atriat mass detected at cardiac ultrasound. A cardiac magnetic resonance (CMR) was performed as a complementary preoperative diagnostic tool. As a peculiar finding, we observed a preserved systolic thickening of the right atrial wall (Supplementary data online, Video S1). The right atrial free wall and the interatrial septum, involved by the tumour, showed a systolic thickening of 41 and 47%, respectively: a normal wall motion despite increased wall thickness (Panels A and 8). Whether the atrial wall thickening represents a partial separation of the bulk of the tumour from the rest of the atrial wall (but neither cleavage nor significant CMR signal differences inside the wall were detected), or a thickening of the atrial wall overlying the tumour, the thickening is systolic and measurable. However, the contraction was also observed in the interatrial septum representing thus a peculiarity of the tumour. To the best of our knowledge, this feature has never been described in cardiac tumours. A diagnosis of hamartoma of mature cardiac myocytes (HMCMs) was made at histological examination.
