Abstract
BACKGROUND: Prevalence of bicuspid aortic valve (BAV) and right aberrant subclavian artery (ASA) separately is relatively common in general population, and much higher in some disorders. Surprisingly, coexistence of both valve and vessel anomalies has only been reported in single cases.
METHODS: From 2008 to 2016, in a single, high-volume tertiary cardiac center, patients who underwent chest computed tomography or magnetic resonance imaging for various reasons, were retrospectively screened for the presence of right ASA.
RESULTS: 78 patients with either right or left ASA were identified. Among them eight cases of BAV and right ASA coexistence were identified. In seven patients right ASA was diagnosed by computed tomography, and in one patient by magnetic resonance. Additionally, three cases with coexisting common origin of carotid arteries (COCA) were visualized in this subgroup.
CONCLUSIONS: Although coexistence of ASA and BAV has not been reported in pediatric population, it has been diagnosed in very few adults as well as in our series. Additional presence of COCA in this group seems to be very rare. From practical point of view, heart cannulation via the radial artery and subsequent ASA may be challenging. Similarly, COCA presence may have surgical implications during corrective procedures.
