A method for manufacturing a prosthetic heart valve using a pericardium, the method comprising: preparing three heterogeneous tissue pieces , the heterogeneous tissue pieces extracted in a quadrangular shape from a bovine pericardium or a porcine pericardium, folding each of the heterogeneous tissue pieces to form an inside tissue piece on an inside and an outside tissue piece on an outside, the outside tissue piece having a greater length than the inside tissue piece , connecting respectively the inside and outside tissue pieces , by sewing with a first connecting thread along a semicircular shape having one side open, such that each of the inside tissue pieces has a valve piece formed on an inside of the first connecting thread and a securing piece formed on an outside of the first connecting thread , arranging the heterogeneous tissue pieces next to one another to form a cylindrical form, placing both ends of the heterogeneous tissue pieces in contact with one another and exposing outward to connect the heterogeneous tissue pieces by sewing with a second connecting thread along a vertical direction, folding the heterogeneous tissue pieces at both ends to complete a valve conduit having folded portions , preparing a wire stent by intertwining wires made of a superelastic shape-memory alloy along a circumferential direction and a lengthwise direction of a cylinder in a network form, the wire stent comprising a cylindrical body having a plurality of spaces formed therein and expanding portions expanding outward from both sides of the cylindrical body , inserting the valve conduit into an inside of the wire stent and connecting the spaces and the outside tissue pieces and the securing pieces by sewing with a third connecting thread along a horizontal direction to complete a valve conduit stent , wherein the valve conduit stent is compressed by a commonly used crimper and latched onto a hook portion of a catheter and is inserted into an outer tube of the catheter by a movement of the hook portion . preparing three heterogeneous tissue pieces , the heterogeneous tissue pieces extracted in a quadrangular shape from a bovine pericardium or a porcine pericardium, folding each of the heterogeneous tissue pieces to form an inside tissue piece on an inside and an outside tissue piece on an outside, the outside tissue piece having a greater length than the inside tissue piece , connecting respectively the inside and outside tissue pieces , by sewing with a first connecting thread along a semicircular shape having one side open, such that each of the inside tissue pieces has a valve piece formed on an inside of the first connecting thread and a securing piece formed on an outside of the first connecting thread , arranging the heterogeneous tissue pieces next to one another to form a cylindrical form, placing both ends of the heterogeneous tissue pieces in contact with one another and exposing outward to connect the heterogeneous tissue pieces by sewing with a second connecting thread along a vertical direction, folding the heterogeneous tissue pieces at both ends to complete a valve conduit having folded portions , preparing a wire stent by intertwining wires made of a superelastic shape-memory alloy along a circumferential direction and a lengthwise direction of a cylinder in a network form, the wire stent comprising a cylindrical body having a plurality of spaces formed therein and expanding portions expanding outward from both sides of the cylindrical body , inserting the valve conduit into an inside of the wire stent and connecting the spaces and the outside tissue pieces and the securing pieces by sewing with a third connecting thread along a horizontal direction to complete a valve conduit stent , wherein the valve conduit stent is compressed by a commonly used crimper and latched onto a hook portion of a catheter and is inserted into an outer tube of the catheter by a movement of the hook portion . <EOS>
