Numerical predictions of shear stress and cyclic stretch in the healthy pulmonary vasculature [PDF]
arXiv, 2021 Isolated post-capillary pulmonary hypertension (Ipc-PH) occurs due to left heart failure, which contributes to 1 out of every 9 deaths in the United States. In some patients, through unknown mechanisms, Ipc-PH transitions to combined pre-/post-capillary PH (Cpc-PH), diagnosed by an increase in pulmonary vascular resistance and associated with a ...

In silico modeling of oxygen-enhanced MRI of specific ventilation. [PDF]
, 2018 Specific ventilation imaging (SVI) proposes that using oxygen-enhanced 1H MRI to capture signal change as subjects alternatively breathe room air and 100% O2 provides an estimate of specific ventilation distribution in the lung.

Topology Repairing of Disconnected Pulmonary Airways and Vessels: Baselines and a Dataset [PDF]
arXiv, 2023 Accurate segmentation of pulmonary airways and vessels is crucial for the diagnosis and treatment of pulmonary diseases. However, current deep learning approaches suffer from disconnectivity issues that hinder their clinical usefulness. To address this challenge, we propose a post-processing approach that leverages a data-driven method to repair the ...

Journal of the Practice of Cardiovascular Sciences, 2019 Total anomalous pulmonary venous connection (TAPVC) consists of abnormality of blood flow in which all pulmonary veins drain into systemic veins or into right atrium with or without pulmonary venous obstruction. Systemic and pulmonary venous blood mix in

In-silico analysis of the influence of pulmonary vein configuration on left atrial haemodynamics and thrombus formation in a large cohort [PDF]
arXiv, 2022 Atrial fibrillation (AF) is considered the most common human arrhythmia. Around 99\% of thrombi in non-valvular AF are formed in the left atrial appendage (LAA). Studies suggest that abnormal LAA haemodynamics and the subsequently stagnated flow are the factors triggering clot formation.

Efficient Anatomical Labeling of Pulmonary Tree Structures via Deep Point-Graph Representation-based Implicit Fields [PDF]
, 2023 Pulmonary diseases rank prominently among the principal causes of death worldwide. Curing them will require, among other things, a better understanding of the complex 3D tree-shaped structures within the pulmonary system, such as airways, arteries, and veins.
