Bioprosthetic Valve Fracturing in Valve‐in‐Valve TAVI: Clinical and Echocardiographic Outcomes in Failing Perimount Aortic Bioprostheses—A Multicenter Registry

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Data comparing clinical and hemodynamic outcomes of bioprosthetic valve fracturing (BVF) and “standard”‐postdilatation during valve‐in‐valve transcatheter heart valve implantation (ViV‐TAVI) are lacking. The authors aimed to analyze hemodynamic and clinical outcomes of BVF compared to “standard”‐postdilatation during ViV‐TAVI ...

Comparison of Latest Generation Intra‐ and Supra‐Annular Self‐Expanding Transcatheter Heart Valves for Aortic Valve‐in‐Valve Procedures

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Valve‐in‐valve (ViV) procedures are an established therapy. Self‐expanding (SE) supra‐annular transcatheter heart valves (THV) achieve superior hemodynamics compared to balloon‐expandable (BE) intra‐annular THV, but influence of stent design versus valve position remains unclear. Aims This study compares SE intra?

Noncalcific Mechanisms of Bioprosthetic Structural Valve Degeneration

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Bioprosthetic heart valves (BHVs) largely circumvent the need for long‐term anticoagulation compared with mechanical valves but are increasingly susceptible to deterioration and reduced durability with reoperation rates of ≈10% and 30% at 10 and 15 years,

Aortic valve replacement in patients aged 50 to 70 years: Improved outcome with mechanical versus biologic prostheses [PDF]

open access: yes, 2008
ObjectiveImproved durability of bioprostheses has led some surgeons to recommend biologic rather than mechanical prostheses for patients younger than 65 years.

Normally and abnormally functioning left-sided porcine bioprosthetic valves after long-term implantation in patients: Distinct spectra of histologic and histochemical changes [PDF]

open access: yes, 1984
This morphologic study (X-ray examination of gross specimens, histologic study and histochemical staining) compares two groups of explanted left-sided biopros-thetic valves: group 1,6 valves with normal cusp function and group II, 10 valves with ...

The International TrifectaTM and EpicTM Valve‐in‐Valve Registry: Insights Into Clinical & Hemodynamic Outcomes

open access: yesCatheterization and Cardiovascular Interventions, Volume 105, Issue 7, Page 1711-1718, June 1, 2025.
ABSTRACT Background Little is known about the clinical and hemodynamic outcome of valve‐in‐valve transcatheter aortic valve replacement (ViV‐TAVR) for failed Trifecta surgical aortic bioprotheses. Aims We aimed to compare outcomes of valve‐in‐valve transcatheter aortic valve replacement (ViV‐TAVR into failed TrifectaTM vs.

In Vitro Evaluation of Biomaterials for Heart Valve Prosthesis: High Hydrostatic and Enzymatic Treatments as Alternative for Bio‐Derived Materials

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 6, June 2025.
ABSTRACT Various biomaterials are currently used in clinical settings for heart valve repair and replacement. However, the optimal tissue preparation technique remains elusive. In this study, a non‐crosslinked tissue obtained from bovine pericardium, developed by Adeka Corporation, was compared with three commercially‐available tissues: two fixed ...
