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

, 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 ...

Presence Of A Congenitally Bicuspid Aortic Valve Among Patients Having Combined Mitral And Aortic Valve Replacement [PDF]

, 2012
Although bicuspid aortic valve occurs in an estimated 1% of adults and mitral valve prolapse in an estimated 5% of adults, occurrence of the 2 in the same patient is infrequent.

Laser Doppler anemometry measurements of steady flow through two bi-leaflet prosthetic heart valves

Brazilian Journal of Cardiovascular Surgery, 2013
INTRODUCTION: In vitro hydrodynamic characterization of prosthetic heart valves provides important information regarding their operation, especially if performed by noninvasive techniques of anemometry. Once velocity profiles for each valve are provided,

Evolving technology: the TRIFLO tri-leaflet mechanical valve without oral anticoagulation: a potential major innovation in valve surgery

Frontiers in Cardiovascular Medicine, 2023
The aortic valve is the most frequently diseased valve and aortic stenosis (AS) is the most prevalent valvular heart disease in developed countries. The diseased native aortic valve can be replaced by either a biological or mechanical valve prosthesis ...

Infection in prosthetic material [PDF]

, 2015
Surgical site infection (SSI) occurs when a wound created as part of a surgical procedure becomes infected. SSI is one of the most common healthcare-associated infections and occurs in approximately 5% of patients undergoing a surgical procedure. SSI may

Tissue Heart Valve Replacement at BSMMU- Initial Experience with Two Cases

Bangabandhu Sheikh Mujib Medical University Journal, 2010
Research on prosthesis to replace diseased heart valves began almost simultaneously with mechanical valves which are durable but with inherent thromboembolic complication requiring life-long anticoagulant therapy and tissue valves which are more prone to

Surgical pulmonary valve replacement at a tertiary adult congenital heart centre in the current era

International Journal of Cardiology Congenital Heart Disease, 2022
Background: Surgical pulmonary valve replacement (PVR) is the standard cardiac operation in adult patients with congenital heart disease (ACHD). We report recent experience at a large tertiary centre and examine the impact of prosthesis type on outcomes.

Transcatheter Aortic Valve Implantation in Dialysis Patients [PDF]

, 2012
Background/Aims: Transcatheter aortic valve implantation (TAVI) has emerged as a new therapeutic option for high-risk patients. However, dialysis patients were excluded from all previous studies.

Choice of heart valve prosthesis [PDF]

Heart, 2002
It is 40 years since Starr and Edwards' description of successful prosthetic valve replacement in 1961. Some patients who underwent valve replacement with the original Starr-Edwards prosthesis in the 1960s are alive to this day. The Starr-Edwards ball and cage prosthesis, albeit in modified form, is still available commercially.

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]

, 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.
