Rare case series of adult interrupted aortic arch.

UNLABELLED: Interrupted aortic arch (IAA) is a rare congenital heart condition where there is a complete discontinuation between the ascending and descending aorta. The association with a patent ductus arteriosus or developed arterial collateral allows survival until adulthood in extremely rare cases. We report a case series of adult forms of IAA. Even if the incidence is very rare, IAA should be could excluded in the setting of resistant asymmetrical hypertension. The first case is singular regarding its association with a bicuspid aortic valve and aortic aneurysm, while the second case is characterized by massive left ventricular hypertrophy. The diagnosis was suspected on echocardiographic findings and confirmed by computed tomography angiography. Both patients refused surgical repair given the high operative risk.

LEARNING OBJECTIVES: -The evaluation of severe resistant high blood pressure should include complementary investigation for adult form interrupted aortic arch.-To understand the major impact of multimodality imaging for the recognition, localization, and stratification of interrupted aortic arch.
