Is distortion of the bioprosthesis ring a risk factor for early calcification ?

Journal of Cardiothoracic Surgery, 2010
Background As the population ages, bioprosthesis are increasingly being used in cardiac valve replacement. Pericardial bioprosthesis combine an excellent hemodynamic performance with low thrombogenicity, but valve failure associated with calcification ...

Pulsed Cavitational Ultrasound Softening

JACC: Basic to Translational Science, 2017
The authors propose a novel noninvasive therapeutic approach for degenerative calcified bioprosthetic heart valves based on pulsed cavitational ultrasound (PCU) to improve the valvular function by remotely softening calcified stiff cusps. This study aims

Experimental Study and Early Clinical Application Of a Sutureless Aortic Bioprosthesis

Brazilian Journal of Cardiovascular Surgery, 2015
INTRODUCTION: The conventional aortic valve replacement is the treatment of choice for symptomatic severe aortic stenosis. Transcatheter technique is a viable alternative with promising results for inoperable patients.

Bicuspid mitral bioprosthesis. [PDF]

Thorax, 1981
A bicuspid mitral bioprosthesis was prepared by mounting glutaraldehyde-processed porcine pericardium onto commercially available Brownlee-Yates stents. The bioprostheses were inserted into 17 dogs. Haemodynamic performance and long-term function of the valve was assessed.

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

, 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.

Biomechanical analysis of novel leaflet geometries for bioprosthetic valvesCentral MessagePerspective

JTCVS Open, 2023
Objectives: Although bioprosthetic valves have excellent hemodynamic properties and can eliminate the need for lifelong anticoagulation therapy, these devices are associated with high rates of reoperation and limited durability.

Off-pump transapical balloon-expandable aortic valve endoprosthesis implantation [PDF]

, 2009
OBJECTIVE: The aortic valve replacement is a routine procedure, and involves replacement of the native valve/prosthesis. In most of the patients who undergo such procedure the risk is acceptable, but in some cases, such risk can justify contraindication.
