Why the study?
Coronary artery anomalies can cause anatomical variations affecting artery origin and trajectory, but concurrent myocardial bridge and anomalous coronary origin cases are unusual.
Case Report (n=1)
INTRODUCTION: Coronary artery anomalies result from disturbances which may occur to the fetus in the third week of development. These disturbances may lead to anatomical variations which may affect the origin, trajectory, and termination of these arteries, or alterations in their intrinsic anatomy. PRESENTATION OF CASE: We report an unusual case in which both anomalous origin of the right coronary artery and myocardial bridge on left anterior descending artery were detected concurrently. DISCUSSION: An investigation for myocardial bridge should be performed in all congenital coronary artery anomalies. CONCLUSION: Invasive testing could be considered in patients with myocardial and equivocal non-invasive functional testing, in order to obtain better risk stratification and treatment.
