Experimental investigation of the flow downstream of a dysfunctional bileaflet mechanical aortic valve [PDF]
arXiv, 2019 Mechanical heart valve replacement is the preferred alternative in younger patients with severe symptomatic aortic valve disease. However, thrombus and pannus formations are common complications associated with bileaflet mechanical heart valves. This leads to risks of valve leaflet dysfunction, a life threatening event.

T Cell Response in Patients with Implanted Biological and Mechanical Prosthetic Heart Valves
Mediators of Inflammation, 2016 The study was aimed at assessing T cell subsets of peripheral blood from recipients of long-term functioning (more than 60 months) biological and mechanical heart valve prostheses.

Tricuspid valve dysplasia in dogs [PDF]
, 2018 A general overview of tricuspid valve dysplasia in dogs is presented in this review. This congenital disease has been described in numerous large dog breeds but especially the Labrador retriever is predisposed.

Restoration of a Stuck Leaflet
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Severe aortic regurgitation (AR) for a leaflet malfunction after transcatheter aortic valve implantation (TAVI) is a dreadful complication that can lead even to cardiogenic shock. New valve's design has reduced the rate of paravalvular regurgitation, however central regurgitation is still a challenging complication.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Patients undergoing transcatheter aortic valve implantation (TAVI) often require long‐term oral anticoagulation (OAC), but it is unclear whether to continue or interrupt OAC during the procedure. This meta‐analysis compares clinical outcomes of continuing versus interrupting OAC during TAVI.

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.

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.

Exercise hemodynamics of bovine versus porcine bioprostheses: A prospective randomized comparison of the mosaic and perimount aortic valves [PDF]
, 2005 ObjectiveThis prospective randomized study compares a porcine with a bovine bioprosthesis in the aortic position with regard to hemodynamic performance during exercise.MethodsBetween August of 2000 and December of 2002, 136 patients underwent aortic ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Transcatheter aortic valve implantation (TAVI) has changed the treatment of aortic stenosis. The Myval transcatheter heart valve (THV), a novel balloon‐expandable THV, has shown promising outcomes. Our aim is to compare the comparative safety and effectiveness of Myval THV against established THVs, such as Sapien and Evolut.
