An invasive cardiac valve includes a tubular stent (1) and a valve (2). One end of the tubular stent (1) is of a frusto-conical structure, the other end is wide open, and the diameter of the open end is greater than the diameter of the frusto-conical end. The valve (2) is attached to the frusto-conical end of the tubular stent (1) a delivery and retrieve hole (4) of the cardiac valve is provided on the top of the open end of the tubular stent (1). Because the diameter of the open end is greater than the diameter of the frusto-conical end, the cardiac valve can be effectively fixed in position of aortic annulus, which can prevent the cardiac valve displacement caused by the blood flow pushing. Because the valve (2) is attached to the frusto-conical end of the tubular stent (1), the valve (2) can totally avoid the left and right coronary ostium and do not affect the haemodynamics of the coronary artery. Because a delivery and retrieve hole (4) of the cardiac valve is provided on the top of the open end of the tubular stent (1), the cardiac valve can be retrieved and reset at any time through a handle if it is discovered to be placed in an improper position during the release process.
