Primary dysfunction of Hancock pericardial bioprosthesis occurred at 3.20% valve-year for mitral and 0.92% for aortic valves. Tearing of cusps was the main cause, highlighting the need for improved valve fitting techniques.

Area of Science:

  • Cardiovascular Surgery
  • Biomaterials Science
  • Medical Device Engineering

Context:

  • Hancock pericardial bioprosthesis used in 432 patients.
  • Mean follow-up of 53.1 months per patient.
  • Previous studies led to discontinuation of Hancock prosthesis.

Purpose:

  • Evaluate the frequency of primary dysfunction in Hancock pericardial bioprosthesis.
  • Analyze causes of bioprosthetic valve dysfunction.
  • Compare long-term results with other pericardial prostheses.

Summary:

  • Primary dysfunction occurred at 3.20% valve-year (mitral) and 0.92% valve-year (aortic).
  • Dysfunction primarily caused by cusp tearing (25 cases) and tissue retraction (4 cases).
  • Pathology revealed fibrin formation leading to tissue retraction or fragilization.

Impact:

  • Highlights need for echocardiographic monitoring of implanted valves.
  • Suggests new pericardial valve fitting techniques could improve mechanical reliability.
  • Emphasizes unquestionable advantages of pericardial valves in thrombogenesis and hemodynamics.
