答:通过心脏移植或病死患者的尸体解剖发现心肌致密化不全(NVM)患者心脏扩大、心肌重量增加、冠状动脉通畅。主要改变为受累的心室腔内多发异常粗大的肌小梁和交错深陷的隐窝,从心底到心尖致密心肌逐渐异常变薄;心内膜为增厚的纤维组织,内层非致密心肌肌束明显肥大并交错紊乱。 A: Cardiac enlargement, myocardial weight gain, and coronary artery patency were found in autopsy of patients with cardiac densification (NVM) through cardiac autopsy in patients undergoing heart transplantation or death. Mainly changed to the involvement of multiple abnormalities in the ventricular cavity trabecular and traumatic staggered deep crypt, from the bottom of the heart to gradually thinning apex dense myocardium; endocardial thickening of the fibrous tissue, the inner non-compact myocardial muscle Bunch obviously hypertrophy and staggered disorder.
