Weathering the storms of climate change: Preparing persons with disabilities and the physiatrists who provide their care for extreme hurricanes

PM&R, EarlyView.
Abstract Climate‐driven disasters have disproportionate and often devastating consequences on individuals with disabilities. Warming ocean and air temperatures are fueling more extreme tropical cyclones, further endangering those living in at‐risk regions.

Aortic Valve Replacement with a Conventional Stented Bioprosthesis versus Sutureless Bioprosthesis: a Study of 763 Patients

Brazilian Journal of Cardiovascular Surgery
Objective: The aim of this retrospective study was to compare early postoperative outcomes after aortic valve replacement (AVR) with sutureless bioprostheses and conventional stented bioprostheses implanted through median sternotomy.

In Vitro Calcification of Bioprosthetic Heart Valves: Method Validation by Comparative Heart Valve Calcification Testing

Artificial Organs, EarlyView.
We have developed a unique method for pre‐clinical heart valve prostheses evaluation of calcification propensity. Results from the test can directly be translated into improvements of prostheses design, materials, and anti‐calcification treatments, and therefore have a significant impact on heart valve prostheses quality and patient care in the future.

A Rare Case of Partial Aortic Mechanical Valve Thrombosis With Intact Mitral Mechanical Valve Presenting With ST-Elevation Myocardial Infarction Patients

Journal of Investigative Medicine High Impact Case Reports, 2020
The incidence of mechanical valve thrombosis (MVT) is around 0.4 per 100 patient-years. Mitral valve thrombosis has a higher incidence than aortic valve thrombosis with a nearly 5-fold increase. Various factors contribute to MVT. The most common cause of

Trial‐Based Hemolysis Modeling to Investigate Operating Modes of Continuous‐Flow LVADs

Artificial Organs, EarlyView.
This work presents a methodology for determining online‐capable hemolysis models for continuous‐flow LVADs, derived from in vitro trials. The models are based on fitting a modified power law and applying the Lagrangian approach. They assist clinicians in selecting treatment strategies that minimize hemolysis, as demonstrated with the Sputnik1 LVAD ...

Successful Fibrinolytic Therapy in a Challenging Obstructive Prosthetic Mitral Valve Thrombosis

Journal of Investigative Medicine High Impact Case Reports, 2020
Prosthetic valve thrombosis is a rare and severe complication of the mechanical prosthetic valve. Management can be challenging due to varying clinical presentation, overlapping features of differential diagnosis, and lack of randomized controlled trials

In Vitro Calcification Evaluation of Polycarbonate Urethane—Impact of Production Processes

Artificial Organs, EarlyView.
The study shows that hot pressing induces chemical changes in PCU, promoting calcification, while solution‐cast patches remain unaffected. ABSTRACT Background Heart valve diseases remain a leading cause of death in industrialized nations. Polycarbonate urethane (PCU) is a promising material for heart valve prostheses due to its biocompatibility and low

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

Artificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.
