Imaging of Bioprosthetic Valve Dysfunction after Transcatheter Aortic Valve Implantation

Diagnostics, 2023
Transcatheter aortic valve implantation (TAVI) has become the standard of care in elderly high-risk patients with symptomatic severe aortic stenosis. Recently, TAVI has been increasingly performed in younger-, intermediate- and lower-risk populations ...

Performance of xenogeneic pulmonary visceral pleura as bioprosthetic heart valve cusps in swine

Frontiers in Cardiovascular Medicine, 2023
ObjectiveBovine pericardium is common biological material for bioprosthetic heart valve. There remains a significant need, however, to improve bioprosthetic valves for longer-term outcomes.

Bioprosthetic tricuspid valve stenosis in a case of rheumatic mitral valve stenosis and tricuspid valve replacement

Journal of the Practice of Cardiovascular Sciences, 2022
Very little is known about the occurrence of bioprosthetic tricuspid valve stenosis in the Indian population that usually occurs within 8–10 years following tricuspid valve replacement (TVR) with a bioprosthetic valve.

Circulating Progenitor Cells Are Associated With Bioprosthetic Aortic Valve Deterioration: A Preliminary Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Mechanisms underlying bioprosthetic valve deterioration are multifactorial and incompletely elucidated. Reparative circulating progenitor cells, and conversely calcification‐associated osteocalcin expressing circulating progenitor cells, have ...

Porcine or Bovine Tissue Valves: Which are Better for Surgical Aortic Valve Replacement? [PDF]

Journal of Biomedical & Clinical Research, 2023
The choice between mechanical and bioprosthetic aortic valve implants is affected by relatively clear criteria. However, the choice between porcine or pericardial valve is more complex regarding bioprosthetic devices.

Intracardiac Echocardiography to Diagnose Bioprosthetic Pulmonary Valve Thrombosis

JACC: Case Reports, 2021
A 48-year-old woman presented with heart failure and bioprosthetic pulmonary valve regurgitation 2 years after pulmonary valve replacement. Intracardiac echocardiography demonstrated uniform thickening of a single prosthetic valve leaflet suggesting ...

Valve-in-valve transcatheter aortic valve replacement on a self-expandable nitinol frame due to degeneration of primary bioprosthetic valve cusps. Clinical case of a high-risk surgical female patient

Вестник трансплантологии и искусственных органов, 2020
Introduction. We present the clinical observation of a 72-year-old female patient with high surgical risk and structural degeneration of a bioprosthetic aortic valve (AV) cusps in the form of stenosis, accompanied by severe dysfunction.

Unexpected bioprosthetic mitral valve thrombus during left ventricular assist device implantation

JA Clinical Reports, 2017
Acute bioprosthetic valve thrombosis can occur after surgery and sometimes cause hemodynamic instability and cardiogenic shock. Risk factors for bioprosthetic valve thrombosis are hypercoagulability, atrial fibrillation, atrial dilatation, low cardiac ...
