Patient-specific image-based computer simulation for theprediction of valve morphology and calcium displacement after TAVI with the Medtronic CoreValve and the Edwards SAPIEN valve [PDF]

open access: yes, 2016
AIMS: Our aim was to validate patient-specific software integrating baseline anatomy and biomechanical properties of both the aortic root and valve for the prediction of valve morphology and aortic leaflet calcium displacement after TAVI.

Aortic Valve Reconstruction with Ozaki Technique

open access: yesBrazilian Journal of Cardiovascular Surgery, 2021
Modern bioprostheses offer a complete and definitive solution to elderly patients who need aortic valve surgery. Nonetheless, the scenario is more demanding when dealing with younger and less fragile patients. In this setting, any prosthetic aortic valve

Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]

open access: yes, 2019
An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

Under pressure: The first valve-in-valve transcatheter aortic valve implantation for stenosis of a BioValsalva prosthesis using a Sapien 3 Ultra balloon expandable valve in a patient with complex congenital heart disease

open access: yesHeart, Vessels and Transplantation, 2022
Advances in the diagnosis and management of congenital heart disease (CHD) have resulted in an increased number of patients living into adulthood. Despite increased survival, these patients often require surgery at a young age and are susceptible to developing complications related to the degeneration of surgical prostheses and valves.

Bridging aortic valve surgery to 21st century. what can a surgeon do [PDF]

open access: yes, 2019
Aortic valve stenosis is the most clinically relevant valvular heart disease in the elderlies. Surgical aortic valve replacement (SAVR) represented, for decades, the standard of care for the treatment of severe aortic stenosis.

Transcatheter Valve Unable to Cure Patient–Prosthesis Mismatch of Mosaic Bioprosthesis

open access: yesThe Thoracic & Cardiovascular Surgeon Reports, 2016
Transcatheter aortic valve implantation (TAVI) has been recently established as a less invasive alternative to conventional aortic valve replacement (CAVR) in patients presenting with expected high procedural risk.

Interdisciplinary three-step strategy to treat aortic stenosis and coronary artery disease in a patient with end-stage chronic obstructive pulmonary disease [PDF]

open access: yes, 2012
Background: Valvular aortic stenosis is a common disease in the elderly, often in multimorbid patients. It is often associated with coronary artery disease and peripheral artery disease.
