Prevalence and Morphology of Left Anterior Descending (LAD) Myocardial Bridges (MBs) Detected in Children by Coronary CTA (CCTA)

Purpose or Case Report: To evaluate by CCTA the prevalence and morphology of pediatric LAD MBs (coronary segments that contact or tunnel within myocardium), which are common and usually incidental in adults but only sporadically reported in children.
Methods & Materials: All consecutive CCTAs performed at our institution using a Siemens Flash CT from 10/2016 through 9/2019 on patients Results: 144 CCTAs were reviewed, 96 (66.7%) in females, with mean +/- SD age of 11.2 +/- 5.0 yr, 44 (30.6%) with an aberrant RCA. MBs were detected in 111 (77.1%); 15 (10.4%) had 2 MBs. Of the 126 MBs, 67 (53.2%) were grade 1, 48 (38.1%) grade 2, and the rest grade 3. Most (108, 85.7%) began in the mid LAD, with mean distance from the LAD origin, length, and mass index (MMI=length*grade) of 33.2 +/- 18.5 mm, 20.5 +/- 15.0 mm, and 34.2 +/- 3.4, respectively. Among the 11 grade 3 MBs, mean myocardial depth, LAD diameters at end-systole and diastole, and %compression were 1.8 +/- 0.9 mm, 1.9 +/- 0.3 mm, 2.8 +/- 0.6 mm, and 32.6 +/- 15.6%, respectively. MB prevalence rates were not statistically different (p=0.28) in anomalous RCA (31/44, 70.5%) and normal groups (80/100, 80.0%). In multivariate models, greater weight was associated with slightly increased odds of higher grade bridges (OR=1.05, p=0.034); there were no statistically significant predictors of MB presence, length, or MMI.
Conclusions: LAD MBs
