We report a clinical case of a 45-year-old male with a diagnosis of inferior myocardial infarction and previous history of rheumatic fever during his childhood. Coronary angiography demonstrated normal coronary arteries. Transthoracic echocardiogram showed hypokinetic left ventricular inferolateral wall and mitral stenosis; furthermore, speckle tracking analysis revealed reduction of global longitudinal strain involving the inferior wall. A three-dimensional transesophaegeal echocardiography, performed to better characterize the anatomy of the valve and to find possible source of embolic infarct in an enlarged left atrium, showed rheumatic valvular involvement. Cardiac magnetic resonance confirmed the ischemic damage and also provided prognostic information. A multimodality imaging approach should be mandatory in patients with acute myocardial infarction and normal coronary angiography, to define possible sources of embolic infarction and to quantify myocardial damage.
我们报告了一例临床病例,患者为45岁男性,诊断为下壁心肌梗死,童年时有风湿热病史。冠状动脉造影显示冠状动脉正常。经胸超声心动图显示左心室下外侧壁运动减弱及二尖瓣狭窄;此外,斑点追踪分析显示下壁整体纵向应变降低。为更好地明确瓣膜解剖结构并寻找扩大的左心房中可能的栓塞性梗死来源而进行的三维经食管超声心动图显示有风湿性瓣膜受累。心脏磁共振成像证实了缺血性损伤并提供了预后信息。对于急性心肌梗死且冠状动脉造影正常的患者,应采用多模态成像方法来确定可能的栓塞性梗死来源并量化心肌损伤。
