Computer aided design renderings of the commissure geometric alignment device. This device contains the left ventricular outflow tract base, the left ventricular outflow tract mount, the distal aortic outflow mount, and a threaded mounting post where a custom-sized c-arm is attached. The position of the c-arm can be adjusted along the height of the anchor, allowing for commissure height adjustment. Along the c-arm, multiple anchor sites were designed such that commissure anchors can be secured onto the c-arm to adjust the inter-commissure angle
