Selection of Prosthesis in Aortic Valve Surgery: Short Review and Trend in our Practice in 10 Years
Albanian Journal of Trauma and Emergency SurgeryIntroduction: 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.

Tissue Heart Valve Replacement at BSMMU- Initial Experience with Two Cases [PDF]
, 2010 Research on prosthesis to replace diseased heart valves began almost simultaneously with mechanical valves which aredurable but with inherent thromboembolic complication requiring life-long anticoagulant therapy and tissue valves whichare more prone to ...

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

ESC Heart Failure, EarlyView.Abstract A 31‐year‐old male presented with unexplainable symptoms of heart failure including recurrent fatigue and orthopnoea after total arch replacement for type A aortic dissection 2 months ago. Computed tomography angiography detected a severe intra‐luminal stenosis, and we successfully implanted a balloon‐expandable stent to dilate the stenosis ...

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

Fluid dynamics of heart valves during atrial fibrillation: a lumped parameter-based approach [PDF]
, 2015 Atrial fibrillation (AF) consequences on the heart valve dynamics are usually studied along with a valvular disfunction or disease, since in medical monitoring the two pathologies are often concomitant. Aim of the present work is to study, through a stochastic lumped-parameter approach, the basic fluid dynamics variations of heart valves, when only ...

Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]
arXiv, 2022 Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

Q-fever prosthetic valve endocarditis in a patient with SLE and antiphospholipid antibody syndrome
Journal of Infection and Public Health, 2020 Q fever prosthetic valve endocarditis in association with antiphospholipid antibody syndrome (APS) in systemic lupus erythematosus (SLE) has not been previously reported. Here, we report a 22-year-old Saudi female diagnosed with SLE and APS.

Cavernous hemangioma of the mitral valve – a rare heart tumor. А clinical case [PDF]
Кардіохірургія та інтервенційна кардіологія, 2018 The article presents a clinical case of a rare benign heart neoplasm – a cavernous mitral valve hemangioma. Infiltrative growth of the tumor led to deformation of the valve with the development of mitral insufficiency and its replacement with a ...
