Summary
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.
