Dexamethasone is now frequently used in the treatment of bronchopulmonary dysplasia. We report on two premature babies receiving dexamethasone who developed symptomatic myocardial hypertrophy and left ventricular outflow tract obstruction, as documented by M-mode echocardiography and Doppler studies. A normal heart was recorded on echocardiography before and after dexamethasone treatment. The patients had no known risk factors associated with the development of obstructive hypertrophic cardiomyopathy.
地塞米松目前常用于治疗支气管肺发育不良。我们报告了两名接受地塞米松治疗的早产儿，他们出现了有症状的心肌肥厚和左心室流出道梗阻，这已通过M型超声心动图和多普勒研究得到证实。在使用地塞米松治疗前后，超声心动图记录显示心脏正常。这两名患者没有已知的与梗阻性肥厚型心肌病发生相关的危险因素。
