Special type B interrupted aortic arch diagnosis by angiography in an adult patient: a case report.

Abstract

Interrupted aortic arch is an uncommon cardiac anomaly characterised by a lack of continuity between the ascending and descending aorta. The presence of interrupted aortic arch in adults is extremely rare, and there is limited documentation of such cases in the literature. In this article, we present a unique case of interrupted aortic arch in an adult diagnosed through angiography. This case falls under the anatomical classification of type B interruption, although the blood supply to the left subclavian artery originates from the ascending aorta. Its haemodynamic characteristics are completely different from those of the classical type B interruption.
