Cardiac allograft dysfunction is a major cause of morbidity and mortality in the early post-transplantation period. This is a critical condition that requires prompt diagnosis and management. We present the case of a 57-year-old man with ischemic cardiomyopathy who underwent cardiac transplantation and developed a rare case of coronary artery thrombosis in the setting of heparin-induced thrombocytopenia and thrombosis syndrome (HITTS) within the first 2 postoperative weeks. Transmural myocardial infarction (MI) was initially noted on cardiac magnetic resonance (CMR) imaging as regional left ventricular wall motion abnormalities and transmural hyperenhancement after gadolinium administration, prompting further evaluation of the coronary circulation with angiography.
心脏移植后功能障碍是移植后早期发病和死亡的主要原因。这是一种危急情况，需要及时诊断和处理。我们报告一例57岁缺血性心肌病男性患者，该患者接受了心脏移植，术后第2周内，在肝素诱导的血小板减少和血栓形成综合征（HITTS）背景下发生了罕见的冠状动脉血栓形成。心脏磁共振（CMR）成像最初显示透壁性心肌梗死（MI）表现为局部左心室壁运动异常和钆剂注射后透壁性强化，促使通过血管造影进一步评估冠状动脉循环。
