CARDIAC VALVE PROSTHESIS AND METHOD OF IMPLANTATION THEREOF Russian patent published in 2009 - IPC A61F2/24 A61B17/00 

FIELD: medicine; cardiosurgery.

SUBSTANCE: cardiac valve prosthesis contains rigid circular enclosure, obturative element installed within enclosure clearance, obturative element and enclosure junction and supraannular sewed-on cuff. Furthermore it accommodates subannular sewed-on cuff of radial dimension smaller than that of supraannular cuffs. The first stage involves that fixing suturing threads are delivered through subannular cuff of the prosthesis or behind the ventricular edge of tissue coating of the prosthesis enclosure containing one sewed-on cuff, or through the basement of the prosthesis sewed-on cuff containing one sewed-on cuff. The second stage implies through tissue fibrous ring of the natural cardiac valve from its ventricular surface, while for the third stage through the prosthesis supraannular cuff or through sewed-on cuff closer to its free edge for the prosthesis containing one sewed-on cuff.

EFFECT: reduced or eliminated prosthesis-patient inadequacy after cardiac valve prosthetics.
