Objective
Multidetector computed tomography is considered a reliable, non-invasive modality for diagnosing myocardial bridging. The prevalence of myocardial bridges varies greatly based on the technique used to identify the anomaly. We aimed to evaluate the frequency and morphological features of myocardial bridging in patients who underwent ECG-gated 640 slice Multidetector computed tomography coronary angiography at Shahid Gangalal National Heart Centre.
Methods
A retrospective cross-selectional study was conducted at Shahid Gangalal National Heart Centre. From 1 January 2021 to 30 June 2021, 1068 consecutive patients were enrolled, and the frequency and morphological features of myocardial bridging among those patients were evaluated.
Results
Among the 1068 patients examined, 141 had one or multiple Myocardial bridging (13.2%). Out of 141 patients, 94.3% of bridging was superficial, while only 5.7% was deep. 97.9% of myocardial bridging was located in the left anterior descending artery, and 86.2% was present in the mid-segment of the left anterior descending artery.
Conclusion
Multidetector computed tomography is an effective noninvasive method for the diagnosis of myocardial bridging. The frequency of myocardial bridging in our study was 13.2%.
