Prediction of Turbulent Shear Stresses through Dysfunctional Bileaflet Mechanical Heart Valves using Computational Fluid Dynamics

, 2018
There are more than 300,000 heart valves implanted annually worldwide with about 50% of them being mechanical valves. The heart valve replacement is often a common treatment for severe valvular disease.

Current Application Status and Innovative Development of Surgical Robot

Med Research, EarlyView.
Advantage, Challenge and Innovation of surgical robots. ABSTRACT Surgery has undergone a revolutionary development since the innovations in anesthesiology, aseptic techniques, and antibiotics. The use of modern techniques, especially minimally invasive techniques, has led to a new era of microsurgery and reduced patient trauma.

Economic Burden of Inpatient Care for Mitral Regurgitation in Maryland

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Mitral regurgitation (MR) is the most common valvular disease in the United States and increases the risk of death and hospitalization. The economic burden of MR in the United States is not known.

In vitro characterization of hemodynamics in bicuspid aortic valves: The impact of valve and ascending aortic morphologies

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose This study investigated the effect of bicuspid aortic valve (BAV) morphology and ascending aortic curvature (AAAc) bending angles on aortic hemodynamics, focusing on transvalvular jets and secondary helical flows that contribute to systolic hemodynamic stress linked to aortic complications.

Aged Zebrafish as a Spontaneous Model of Cardiac Valvular Disease

Aging Cell, EarlyView.
Natural ageing in zebrafish results in spontaneous development of valvular degeneration in both the atrioventricular (AV) and bulboventricular (BV) valves. Aged zebrafish valves are larger and exhibit cystic regions, immune cell infiltration, early osteoblast differentiation and increased regurgitation.

Paravalvular leakage after mitral valve replacement: improved long-term survival with aggressive surgery? [PDF]

, 2017
Background: Following mitral valve replacement, surgical closure of paravalvular leaks is usually advised in severely symptomatic patients and in those requiring blood transfusions for persisting haemolysis.

Associations between persistent postoperative anaemia and mortality 1 year after valvular heart surgery: a retrospective cohort study*

Anaesthesia, EarlyView.
Summary Introduction Peri‐operative anaemia is a common problem in patients undergoing cardiac surgery. Postoperative anaemia is not well understood relative to pre‐operative anaemia; limited data exist on haemoglobin recovery and mortality after discharge, especially in the era of restrictive transfusion practice.
