未经证实:左心房夹层是与心脏手术相关的罕见实体,导管介入手术,或者心脏创伤.也报道了自发性病例。左心房夹层的进入常发生在二尖瓣后环,这也是二尖瓣环钙化(MAC)的有利部位。我们在此报告了一例罕见的由MAC破坏引起的自发性左心房夹层。
未经评估:一名84岁女性因胸部不适入院。经胸超声心动图显示二尖瓣后环严重钙化,左心房后壁与MAC相邻。经食管超声心动图显示血流通过MAC从左心室进入肿块。心脏计算机断层扫描显示MAC的破坏,这是左房夹层和血肿的入口。保守的方法继续,由于血流动力学状态稳定,并且由于她的虚弱和许多并发症。6个月随访期间未发生其他事件,虽然假腔没有消退。
未经证实:心内肿块的诊断具有挑战性。在我们的案例中,采用多种成像方式进行的详细解剖学评估使我们能够了解疾病并对其进行适当管理.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
