Bioprosthetic Aortic Valve Replacement in <50 Years Old Patients – Where is the Evidence?

open access: yesBrazilian Journal of Cardiovascular Surgery, 2019
Aortic valve disease is one of the most common valvular heart diseases in the cardiovascular category. Surgical replacement of the diseased aortic valve remains the definitive intervention for most diseases.

Transcatheter tricuspid valve‐in‐valve implantation for degenerative surgical bio‐prosthesis using SAPIEN 3: A case series

open access: yesClinical Case Reports, 2021
We evaluated early outcomes of transcatheter valve‐in‐valve (ViV) implantation in patients with degenerated bio‐prosthesis in tricuspid position. Total of 5 patients were included in our case series.

Allegra Transcatheter Heart Valve inside a Degenerated Sutureless Aortic Bioprosthesis

open access: yesThe Thoracic & Cardiovascular Surgeon Reports, 2021
Transcatheter aortic valve-in-valve implantation (VIV) is increasingly being used to successfully treat degenerated surgical aortic valve bioprostheses (SAVs).

Experimental investigation of the flow downstream of a dysfunctional bileaflet mechanical aortic valve [PDF]

open access: yesarXiv, 2019
Mechanical heart valve replacement is the preferred alternative in younger patients with severe symptomatic aortic valve disease. However, thrombus and pannus formations are common complications associated with bileaflet mechanical heart valves. This leads to risks of valve leaflet dysfunction, a life threatening event.

Modeling the Mitral Valve [PDF]

open access: yes, 2019
This work is concerned with modeling and simulation of the mitral valve, one of the four valves in the human heart. The valve is composed of leaflets, the free edges of which are supported by a system of chordae, which themselves are anchored to the papillary muscles inside the left ventricle.

Transcatheter aortic valve‐in‐valve implantation of a corevalve in a degenerated stenotic sapien heart valve prosthesis

open access: yesCatheterization and cardiovascular interventions, 2013
Treatment options for re‐stenotic aortic valve prosthesis implanted by transcatheter technique have not been evaluated systematically. We describe the case of a 75‐year‐old dialysis patient who was treated by transcatheter aortic valve implantation 3.5 ...

Selection of Prosthesis in Aortic Valve Surgery: Short Review and Trend in our Practice in 10 Years

open access: yesAlbanian Journal of Trauma and Emergency Surgery
Introduction: In our country, the predominant condition treated in aortic valve surgery in its early stages was aortic valve disease of rheumatic origin, primarily in patients under the age of 60.

3D Printing-Assisted Energy Loss Testing of Artificial Aortic Heart Valves [PDF]

open access: yesarXiv, 2019
With the development of additive manufacturing, 3D printing technology has become more common nowadays. We designed and 3D printed a cost-effective liquid fluid pressure measurement device that can convert liquid pressure to air pressure. Air pressure was measured by a low-cost manometer in this study.
