Double aortic arch with bilateral interruptions is a rare abnormality. Indeed, to the best of our knowledge, it has not previously been reported before. Rare variants, such as a double arch with ligamentous atresia of the left component and double arch with bilateral coarctation, have received previous attention. These rare examples can pose significant diagnostic challenges for those relying on transthoracic echocardiography. Use of cardiac CT or MRI is now critical for prompt surgical planning and correction.
