Background: Percutaneous pulmonary valve implantation (PPVI) has emerged as a less invasive alternative for treating severe pulmonary regurgitation after tetralogy of Fallot (TOF) repair in patients ...
Among the most dangerous issues facing patients in need of replacement mechanical heart valves is aortic regurgitation — a ...
Purpose: Current intervention guidelines for bicuspid aortic valve (BAV) associated ascending aorta (AAo) dilatation are suboptimal predictors of clinical outcome. There is growing interest in ...
Researchers have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart's aortic valve and the surrounding structures that mimic the exact look and feel of a ...
Scientists are making custom 3D-printed replicas of human hearts in an effort to improve replacement valve procedures, according to a study that holds promise to optimize the life-saving technology ...
Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.
Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...
At Fakuma 2023, Hasco will introduce its new 3D-printed hot runner system manifold concept — Streamrunner Shadowfree — which it says will eliminate “shadow formations” behind valve pins or areas of ...
