Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Comparison of 2D and 4D Flow MRI in Neonates Without General Anesthesia

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 71-82, January 2023., 2023
Background Neonates with critical congenital heart disease require early intervention. Four‐dimensional (4D) flow may facilitate surgical planning and improve outcome, but accuracy and precision in neonates are unknown. Purpose To 1) validate two‐dimensional (2D) and 4D flow MRI in a phantom and investigate the effect of spatial and temporal resolution;

Enhanced Drug Effect With Cutting Balloon Followed by Drug Coated Balloon in a Rabbit Model

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Drug‐coated balloon (DCB) are effective treatment options for patients with coronary artery disease and using of scoring or cutting balloon before the DCB usage were recommended. However, the effectiveness of lesion preparation with cutting balloons (CB) followed by DCB (CB + DCB) has not been evaluated before.

Low‐field MRI: Clinical promise and challenges

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023
Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

Pencil‐beam scanning proton therapy for the treatment of glomus jugulare tumours

Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 456-462, December 2022., 2022
The rare locally destructive glomus jugulare tumours could be treated using pencil‐beam scanning proton therapy (an alternative to surgery). Proton therapy provides good local control and acceptable toxicity. This paper reports treatment outcomes, acute and early late toxicities of 12 patients with glomus jugulare tumours.

Physics-informed graph neural networks for flow field estimation in carotid arteries [PDF]

arXiv
Hemodynamic quantities are valuable biomedical risk factors for cardiovascular pathology such as atherosclerosis. Non-invasive, in-vivo measurement of these quantities can only be performed using a select number of modalities that are not widely available, such as 4D flow magnetic resonance imaging (MRI).

DBF-UNet: A Two-Stage Framework for Carotid Artery Segmentation with Pseudo-Label Generation [PDF]

arXiv
Medical image analysis faces significant challenges due to limited annotation data, particularly in three-dimensional carotid artery segmentation tasks, where existing datasets exhibit spatially discontinuous slice annotations with only a small portion of expert-labeled slices in complete 3D volumetric data.

Salvage Trans‐Sylvian Peri‐Insular Hemispherotomy After Embolic Hemispherectomy

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Background Hemispherectomy and hemispherotomy represent well‐established treatments for drug‐resistant hemispheric epilepsy. An alternative endovascular procedure has been explored for cases with challenging surgical anatomy, which seeks to achieve the clinical effect of hemispherectomy via embolization of the major cerebral arteries and ...

Origin of thyroid arteries in a Kenyan population

The Annals of African Surgery, 2012
Introduction: The thyroid gland receives blood supply predominantly from paired superior and inferior thyroid arteries. The superior thyroid artery originates from external carotid while the inferior thyroid artery is a branch of thyrocervical trunk ...
