The aortic arch and its branches form during the third week of embryogenesis. The most common human pattern has the innominate artery, the left common carotid artery and the left subclavian artery all as separate branches. Large imaging studies have shown 70% of people have a normal branching pattern with 20% having a common origin of the innominate artery and left common carotid artery, but these studies were performed without reference to the anatomy of the aortic valve (bicuspid versus tricuspid).Bicuspid aortic valve (BAV) is the commonest congenital cardiac malformation and as the arch branching patterns are developmental in origin we decided to see if the frequency of arch variants in BAV and tricuspid aortic valve (TAV) patients differed, as this has not previously been looked at. We examined Computerised Tomographic aortograms and echocardiograms of BAV and TAV patients to assess the aortic arch branching pattern and any possible association with the valve morphology. 28 BAV and 57 TAV patients were assessed. For BAV the branching patterns were: 86% normal (24/28) and 14% abnormal (4/28), and for TAV: 70% normal (40/57) and 30% abnormal (17/57). Although this is a small study our TAV group demonstrated comparable normal/abnormal arch variants as the published literature, but the BAV group appears to have fewer arch variants. This is the first study in the literature to look at the arch branching variants when consideration of the aortic valve morphology (BAV versus TAV) is taken into account.
