The hemodynamics of transcatheter aortic valves in transcatheter aortic valves
The Journal of Thoracic and Cardiovascular Surgery, 2021 The durability of transcatheter aortic valves (TAVs) remains their greatest disadvantage, given that fixed tissue leaflets are not immune to structural degeneration from calcification and thrombosis. Therefore, a second intervention is necessary, especially given that TAV in low-risk patients has shown noninferior outcomes compared with surgery.

Valve-Sparing Operation in Patients with Aortic Root Aneurysm
Український журнал серцево-судинної хірургії, 2020 Background. Aortic root aneurysm is rare but life-threatening disease which affects not only aortic wall, but aortic valve as well. Valve-sparing operation was developed by Tirone David and gave a chance to save native aortic valve in patients with ...

The living aortic valve: From molecules to function. [PDF]
, 2014 The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle.

The phyllotaxis of the aortic valve
Monaldi Archives for Chest Disease, 2019 Biological systems ubiquitously and inevitably exhibit stochasticity in traits from the molecular level to the multicellular and morphological level. However, there are several examples of natural events that might be described in mathematical terms. Plants grow in a structured and geometric way to maximize their sun exposure for photosynthesis while ...

Frontiers in Physiology, 2017 Bicuspid aortic valve (BAV) is a common congenital cardiac malformation affecting 1–2% of people. BAV results from fusion of two adjacent aortic valve cusps, and is associated with dilatation of the aorta, known as bicuspid valve associated aortopathy ...

Quality of life after aortic valve repair is similar to Ross patients and superior to mechanical valve replacement: A cross-sectional study [PDF]
, 2016 Background: In patients after aortic valve surgery, the quality of life is hypothesized to be influenced by the type of the valve procedure. A cross-sectional study on the postoperative quality of life was carried out in patients after aortic valve ...

Long-term outcomes after transcatheter aortic valve implantation in failed bioprosthetic valves.
European Heart Journal, 2020 AIMS Due to bioprosthetic valve degeneration, aortic valve-in-valve (ViV) procedures are increasingly performed. There are no data on long-term outcomes after aortic ViV.

Aortic valve repair and aortic valve–sparing operations [PDF]
The Journal of Thoracic and Cardiovascular Surgery, 2015 Attempts to correct aortic insufficiency by means of aortic valve repair started soon after the advent of open-chest cardiac surgery. Correction of cusp prolapse was performed by suturing the free margins of 2 cusps from the commissures to the central portion or by excising the noncoronary aortic cusp and sinus, transforming a tricuspid into a bicuspid
