Surgical Repair of Common Arterial Trunk With Ventriculoarterial Septal Defect and Dual Orifice Truncal Valve.

We present a case of a rare example of a ventriculo-arterial septal defect found in a patient with a common arterial trunk, with balanced aortic and pulmonary components, but with separate valvar orifices within the common truncal valve. We managed the lesion using a two-patch approach. Performing a palliative procedure to relieve the elevated right ventricular pressure aided in the preservation of the pulmonary component of the common valve. We validated the success of the technique using postoperative computerized tomography and four-dimensional flow magnetic resonance imaging.

Complex Atrial Baffling Procedures in Left Isomerism With Right- and Left-Hand Topology.

We describe complex atrial baffling procedures in the setting of left isomerism with right-hand as opposed to left-handed ventricular topology. An appropriate understanding of the connections of the systemic and pulmonary veins, along with the internal atrial anatomy, as revealed using 3D printing, allowed for successful biventricular repair.
