Abstract
An invasive cardiac valve comprises a tubular stent () and a valve (). One end of the tubular stent () 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 () is attached to the frusto-conical end of the tubular stent (); and a delivery and retrieval hole () of the cardiac valve is provided at the top of the open end of the tubular stent (). 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 a position of aortic annulus to prevent the cardiac valve displacement caused by the impact of the blood flow. Because the valve () is attached to the frusto-conical end of the tubular stent (), the valve () can totally avoid the left and right coronary ostia and does not affect the haemodynamics of the coronary artery. Because a delivery and retrieval hole () of the cardiac valve is provided at the top of the open end of the tubular stent (), the cardiac valve can be retrieved and reset at any time by handle control if it is found to be placed in an improper position during the release process.
