Improving guidance for the correctability of congenital cardiovascular shunts with increased pulmonary vascular resistance

open access: yesInternational Journal of Cardiology Congenital Heart Disease, 2021
Background: Based upon expert opinion, guidelines have been proposed for the correctability of congenital cardiovascular shunts with increased pulmonary vascular resistance. This study reports the accuracy of published guidelines using a dataset from the

Vascular phyllotaxis transition and an evolutionary mechanism of phyllotaxis [PDF]

open access: yesScientific Reports 5, 15358 (2015), 2012
Leaves of vascular plants are arranged regularly around stems, a phenomenon known as phyllotaxis. A constant angle between two successive leaves is called divergence angle. On the one side, the divergence angle $\alpha_0$ of an initial pattern of leaf primordia at a shoot apex is most commonly an irrational number of about 137.5 degrees, called limit ...

Greedy Graph Searching for Vascular Tracking in Angiographic Image Sequences [PDF]

open access: yesarXiv, 2018
Vascular tracking of angiographic image sequences is one of the most clinically important tasks in the diagnostic assessment and interventional guidance of cardiac disease. However, this task can be challenging to accomplish because of unsatisfactory angiography image quality and complex vascular structures. Thus, this study proposed a new greedy graph

ViG3D-UNet: Volumetric Vascular Connectivity-Aware Segmentation via 3D Vision Graph Representation [PDF]

open access: yesarXiv
Accurate vascular segmentation is essential for coronary visualization and the diagnosis of coronary heart disease. This task involves the extraction of sparse tree-like vascular branches from the volumetric space. However, existing methods have faced significant challenges due to discontinuous vascular segmentation and missing endpoints.
