Abstract
We present the case of a 4-month-old child with atrioventricular canal associated with severe left atrioventricular valve dysfunction who previously underwent 3 surgical valve reconstructions without significant improvement. A Hybrid Melody valve (Medtronic, Minneapolis, MN) insertion was planned. Because of the low weight, the risk of left ventricular outflow tract obstruction was significant and therefore evaluated preprocedurally using a cardiac computed tomography-derived 3-dimensional printed model. In vitro tests showed good anchorage of the valve without subaortic obstruction and the procedure was then achieved with an excellent clinical result.
