Myocardial bridging (MB) is a common congenital condition in which a major coronary artery is covered by a bridge of muscle and narrows during systole. We present a patient with typical angina, severe MB of the left anterior descending artery and atherosclerotic coronary artery disease. In this case, dipyridamole 201Tl SPECT myocardial perfusion imaging, besides detecting coronary artery disease, provided supportive evidence that severe MB can cause myocardial ischemia and was useful for the assessment of the interventional outcome, as well as having played a key role in the clinical decision-making process.
心肌桥（MB）是一种常见的先天性疾病，其中一条主要冠状动脉被肌肉桥覆盖，并在收缩期变窄。我们介绍了一位具有典型心绞痛、左前降支严重心肌桥和动脉粥样硬化性冠状动脉疾病的患者。在这种情况下，双嘧达莫 201Tl SPECT 心肌灌注成像除了检测冠状动脉疾病外，还提供了支持性证据，表明严重的心肌桥可导致心肌缺血，有助于评估介入治疗的结果，并在临床决策过程中发挥了关键作用。
