Transposition of the Pulmonary Veins [PDF]
Circulation, 1958 The seriousness of incomplete transposition of the pulmonary veins has probably been underestimated in the past. Data on 11 patients is presented, including 10 with associated atrial septal defects. Common symptoms were dyspnea, fatigability, and frequent respiratory infections.

Data-Dependent Higher-Order Clique Selection for Artery-Vein Segmentation by Energy Minimization [PDF]
International Journal of Computer Vision 117, 142-158(2016), 2023 We propose a novel segmentation method based on energy minimization of higher-order potentials. We introduce higher-order terms into the energy to incorporate prior knowledge on the shape of the segments. The terms encourage certain sets of pixels to be entirely in one segment or the other.

Pulmonary vein stenosis and the pathophysiology of “upstream” pulmonary veins
The Journal of Thoracic and Cardiovascular Surgery, 2014 Surgical and catheter-based interventions on pulmonary veins are associated with pulmonary vein stenosis (PVS), which can progress diffusely through the "upstream" pulmonary veins. The mechanism has been rarely studied. We used a porcine model of PVS to assess disease progression with emphasis on the potential role of endothelial-mesenchymal transition

Automatic Pulmonary Artery-Vein Separation in CT Images using Twin-Pipe Network and Topology Reconstruction [PDF]
arXiv, 2021 With the development of medical computer-aided diagnostic systems, pulmonary artery-vein(A/V) separation plays a crucial role in assisting doctors in preoperative planning for lung cancer surgery. However, distinguishing arterial from venous irrigation in chest CT images remains a challenge due to the similarity and complex structure of the arteries ...

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 ...

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 ...

Catheter Entrapment in a Pulmonary Vein [PDF]
Chest, 2010 Ablation strategies for the treatment of atrial fibrillation (AF) are associated with several potential complications. During electro-anatomic mapping of the left atrium (LA) before ablation, the ablation catheter was entrapped in the right inferior pulmonary vein (RIPV). After multiple unsuccessful gentle tractions, stronger maneuvers with rotation of

A surprise aberrant pulmonary vein [PDF]
Interactive CardioVascular and Thoracic Surgery, 2017 We report an incidental discovery of the superior pulmonary vein coming from a strange anatomical location when performing a robotic left lower lobectomy. When trying to identify the superior pulmonary vein, an aberrant pulmonary vein was found leading into the innominate vein.

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.
