Biological stented prostheses are the predominant choice for aortic valve replacement, favored in 85% of cases. Advances in durability and reduced reoperation risks make them a reliable option despite newer alternatives.

Area of Science:

  • Cardiovascular Surgery
  • Biomedical Engineering

Background:

  • Biological stented prostheses dominate aortic valve replacement, increasing from 30% to 85% over 15 years.
  • Implantation numbers remain stable despite competing procedures like stentless valves and transcatheter aortic valve implantation.

Purpose of the Study:

  • To review the current trends and indications for biological stented prostheses in aortic valve replacement.
  • To assess the evolving role of biological prostheses in light of new technologies and patient comorbidities.

Main Methods:

  • A comprehensive literature search was conducted for aortic valve replacement studies published between January 2000 and May 2012.

Main Results:

  • Recent revisions in heart valve replacement guidelines favor biological prostheses.

  • Newer generations offer extended durability, reduced reoperation mortality, and increased life expectancy.
  • Comorbidities like chronic renal insufficiency and atrial fibrillation are no longer absolute contraindications for bioprostheses.

    • Conclusions:

    • Stented bioprostheses remain a highly relevant and frequently utilized option for aortic valve replacement.
    • Despite innovative alternatives, biological stented valves continue to be the primary technique for aortic stenosis treatment.
