A mono cusped patch for repairing cardiac outflow tract is disclosed in the present invention, which comprises an inner patch, an external supporting patch and a leaflet. An approximate semicircular slit is provided on the inner patch. The inferior border of the leaflet is set between the inner patch and the external supporting patch along the slit. The inner patch, the inferior border of the leaflet and the external supporting patch are stitched together along the slit edge of the inner patch with sutures. The inferior border of the leaflet is fixed between the inner patch and the external supporting patch. According to this special stitching structure, the present invention also provides a valved conduit of good performance. The leaflets of mono cusped patch and valved conduit are sutured with the inner patch/conduit and external supporting patch/conduit to repair cardiac outflow tract, and the inferior border of leaflet is provided between the inner patch/conduit and external supporting patch/conduit, so that the present invention avoids fixing leaflet only with sutures, makes leaflets more durable and improves postoperative longtime treatment effect of patients significantly.
