A 28-year-old female who had had irradiation on the chest wall at the age of 5 as a remedy for keroid granulation after burn, recently developed congestive heart failure. Severe tricuspid regurgitation was demonstrated by echocardiography with a certain calcification in the cardiac shadow on chest radiogram. Calcified right ventricule and ventricular septum were noticed operatively, which disturbed ventricular motion and also caused tricuspid valve deformity. These calcified myocardium apparently corresponded with the irradiation field. After tricuspid valve replacement, she regained physical activity satisfactorily without congestive heart failure. Because she had no other known causes of cardiac calcification such as hypercalcemia, myocarditits, myocardial infarction or renal diseases, irradiation on the chest wall could be responsible for the severe myocardial calcification.
一名28岁女性，5岁时因烧伤后瘢痕疙瘩肉芽接受胸壁照射治疗，近期出现充血性心力衰竭。超声心动图显示严重三尖瓣反流，胸部X线片心脏阴影有一定钙化。手术中发现右心室和室间隔钙化，干扰心室运动并导致三尖瓣畸形。这些钙化心肌明显与照射野相对应。三尖瓣置换术后，她恢复了令人满意的体力活动，未再出现充血性心力衰竭。由于她没有其他已知的心脏钙化原因，如高钙血症、心肌炎、心肌梗死或肾脏疾病，胸壁照射可能是严重心肌钙化的原因。
