title: Left anterior descending coronary artery myocardial bridging detected by 64-multidetector computed tomography.
abstract: A 59-year-old female came to the clinic to evaluate an operation risk of knee joint arthritis. She has history of hypertension for 6 years. She complained of dyspnea on exercise before. Radionuclide imaging demonstrated large moderate perfusion defect in anterior, anteroseptal, and anterolateral regions with significant reversibility. ECG gated 64-multidetector computed tomography demonstrated the middle third of the left anterior descending coronary artery myocardial bridging. The length of tunneled artery was 23 mm and the depth of tunneled artery was 3 mm. Coronary angiogram confirmed the middle third of the left anterior descending coronary artery myocardial bridging. Multidetector computed tomography is a reliable and noninvasive tool for diagnosing coronary myocardial bridging.
