A semilunar stentless valve is formed entirely of biological tissue, and has a plurality of leaflets that are joined to form an annulus and coapt to form a one-way valve. The leaflets open fully to minimize obstruction. A narrow rim of tissue is provided over commissures where the leaflets join and around a base of the valve for a sewing ring. The valves can be sutured to heart tissue wall in a single suture row.
