Heart valve homografts are gaining renewed interest due to improved viability techniques. Utilizing explanted donor hearts and cryopreservation offers promising alternatives to lifelong anticoagulant therapy for valve repair or replacement.

Area of Science:

  • Cardiovascular Surgery
  • Transplantation Biology
  • Cryopreservation Science

Context:

  • Growing interest in heart valve homografts driven by advancements in tissue viability.
  • Explanted hearts from multi-organ donors are utilized for valve procurement.
  • Cryopreservation techniques enhance the viability and utility of homograft valves.

Purpose:

  • To explore the renewed viability of heart valve homografts.
  • To detail the methods of homograft procurement and preservation.
  • To evaluate the clinical outcomes of homograft valve procedures.

Summary:

  • Renewed interest in heart valve homografts stems from enhanced viability achieved through explanted donor hearts and cryopreservation.
  • Surgical access, often via the right side, facilitates aortic, mitral, and tricuspid valve resection or repair in hereditary cardiopathies.
