Fig 1 The arterial roots are made up of the sinuses supported by intervening ventricular structures. They extend from a virtual basal ring, constructed by joining together the proximal attachments of the leaflets, to the sinutubular junction. The three leaflets of the arterial valves are suspended in semilunar fashion within these cylindrical structures, with the hinge lines of each leaflet crossing the circular anatomic ventriculo-arterial junctions as they extend from the basal rings to the sinutubular junctions. The structure is comparable with both the aortic and pulmonary roots, albeit that in the pulmonary root the supporting ventricular structures are exclusively muscular, whereas in the aortic root they are made up in part of the fibrous continuity with the mitral valve and membranous septum.
