目的探讨儿童心室肌致密化不全的临床特点。方法2002年9月至2004年11月新乡医学院第三附属医院心内科4例男性心室肌致密化不全患者,年龄5～14岁。均采用东芝PV6000,vivid7彩色多普勒超声心动图仪进行检查,探头频率2～4MHz。结果4例均出现不同程度心功能不全和心律失常,未见栓塞。超声心动图均可见多发突入心室腔内的肌小梁和与心室腔交通深陷的小梁间隙。结论儿童心室肌致密化不全是一种少见的先天性心肌病,易合并其他心脏畸形。临床主要表现为心功能不全和心律失常。超声心动图是可靠的诊断方法。
Objective To investigate the clinical features of children with ventricular myocardial degeneration. Methods From September 2002 to November 2004, 4 cases of male patients with ventricular hypertrophy in the Third Affiliated Hospital of Xinxiang Medical College were aged from 5 to 14 years old. Toshiba PV6000 are used, vivid7 color Doppler echocardiography to check the probe frequency 2 ~ 4MHz. Results 4 cases showed varying degrees of cardiac dysfunction and arrhythmia, no embolism. Echocardiography showed multiple intracavitary sudden trabecular invagination and tracheal space trauma deep trabecular. Conclusion Children with ventricular myocardial degeneration is a rare congenital cardiomyopathy, easy to merge other cardiac malformations. The main clinical manifestations of cardiac insufficiency and arrhythmia. Echocardiography is a reliable diagnostic method.
