Definitions

  • the invention relates to a heart valve prosthesis for replacing the aortic valve or pulmonary valve according to the preamble of claim 1, as is known from DE 83 27 414 U1.
  • the sails of the biological heart valve preparation are attached to a wave-shaped plastic carrier.
  • the invention is therefore based on the object of providing a prosthetic heart valve of the type mentioned at the beginning, in which the location at which the commissures of the valve leaflets are anchored can move radially in accordance with the respective pressure conditions when the aorta is expanded or contracted.
  • Fig. 1 is a perspective view of such a heart valve prosthesis
  • FIG. 2 shows a central sectional view through such a heart valve prosthesis, one of the felt strips forming the commissure elements being recognizable in section on the left.
  • the heart valve prosthesis consists of a support ring 10 with a substantially constant height over the circumference.
  • a seam ring 16 is arranged on the outside around the support ring.
  • a biological heart valve preparation - preferably obtained from pork - is sewn to the aortic wall 14 'below and above the anchoring X on the support ring, while the commissures 14 *' of the biological heart valve preparation are attached to the flexible felt strips 12 are sewn on.
  • the suture ring 16 which is firmly connected to the support ring 10
  • the suture ring 16 is sewn close to the heart of the patient's aortic wall.
  • the free ends of the felt strips 12 pointing away from the support ring 10 are attached to the aortic wall of the patient. Due to the resilience of the felt strips 12 forming the commissure elements, the heart valve prosthesis according to the invention behaves approximately like the natural human heart valve: the location at which the commissures of the valve leaflets are anchored moves radially as the aorta widens or narrows Pressure ratios accordingly, which contributes to the reliable function of the valve leaflets.
  • the flow cross-section that can be achieved is larger since the anchoring points of the commissures correspondingly move outwards when the aorta is widened due to the ejection pressure.
  • a divergent flow is brought about because, unlike in the prior art, there are no rigid commissure elements. The dead spaces which form behind the commissure members in the prior art are avoided.
