Successful heart transplantation after 4 years of bridging with HeartWare HVAD for left ventricular noncompaction in an 11-year-old boy with prohibitively high pulmonary vascular resistance

Annals of Pediatric Cardiology
End-stage heart failure due to left ventricular noncompaction (LVNC) poses unique challenges for ventricular assist device implantation, like inflow cannula obstruction due to trabeculations. We report a case of an 11-year-old boy with LVNC who underwent

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...

Hemostatic complications associated with ventricular assist devices

Research and Practice in Thrombosis and Haemostasis, 2019
Hemostatic complications are common in patients with ventricular assist devices. The pathophysiologic mechanisms that lead to dysregulated hemostasis involve complex interactions between device surface, sheer stress, and blood flow. These factors lead to

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Ventricular assist devices as bridge to heart transplantation: impact on post-transplant infections [PDF]

, 2016
BACKGROUND Ventricular assist devices (VAD) are valuable options for patients with heart failure awaiting cardiac transplantation. We assessed the impact of pre-transplant VAD implantation on the incidence of post-transplant infections in a nationwide ...
