description | BACKGROUND: Left atrial dissection is an uncommon entity associated with cardiac surgery, catheter interventional procedures, or cardiac trauma. Spontaneous cases have also been reported. The entry of left atrial dissection often occurs in the posterior annulus of the mitral valve, which is also a favourable site for mitral annular calcification (MAC). We herein report a rare case of spontaneous left atrial dissection caused by a disruption of MAC. CASE SUMMARY: An 84-year-old woman was admitted to our hospital for chest discomfort. Transthoracic echocardiography showed severe calcification of the posterior mitral annulus and a heterogeneous mass in the posterior wall of the left atrium adjacent to MAC. Transoesophageal echocardiography showed blood flow through MAC from the left ventricle into the mass. Cardiac computed tomography showed the disruption of MAC, which was the entry for left atrial dissection and haematoma. The conservative approach was continued, as the haemodynamic state was stable and because of her frailty and many complications. No further events occurred during 6 months follow-up, although the false cavity did not regress. DISCUSSION: The diagnosis of an intracardiac mass can be challenging. In our case, a detailed anatomical evaluation with multiple imaging modalities allowed us to understand the disease and manage it appropriately. |
