Morphological dilemma: Anomalous pulmonary venous confluence or cor triatriatum—does it matter?
Journal of the Saudi Heart Association, 2018 Cardiac variant of total anomalous pulmonary venous return is a rare entity, whereby all the pulmonary veins drain directly to the right atrium or coronary sinus. The effective left heart blood flow channels through a small stretched patent foramen ovale

Translobar Phenomenon of Pulmonary Veins and Its Clinical Significance in Lobectomy
Chinese Journal of Lung Cancer, 2021 Background and objective Lobectomy is the main treatment strategy for early lung cancer. However, there are many anatomical variations in the lungs, especially some pulmonary veins will deviate from the normal position, and even cross the border of lob ...

Vision Transformers increase efficiency of 3D cardiac CT multi-label segmentation [PDF]
arXiv, 2023 Accurate segmentation of the heart is essential for personalized blood flow simulations and surgical intervention planning. Segmentations need to be accurate in every spatial dimension, which is not ensured by segmenting data slice by slice. Two cardiac computed tomography (CT) datasets consisting of 760 volumes across the whole cardiac cycle from 39 ...

JACC: Clinical Electrophysiology, 2016 Durable isolation following pulmonary vein (PV) ablation may not be necessary for effective suppression of atrial fibrillation (AF) in certain patients with AF. However, most patients are thought to benefit from durable PV isolation, because PV reconnection seems to by and large underlie ...

Bioprinted Micro‐Clots for Kinetic Analysis of Endothelial Cell‐Mediated Fibrinolysis
Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.This paper describes the development of a microscale model that quantifies the breakdown of fibrin by endothelial cells. The small size scale of this engineered system enables fibrin breakdown to be observed without the addition of external activators. This system could help in identifying compounds which both promote and hinder thrombosis.

International Journal of Cardiology: Heart & Vasculature, 2015 Stroke remains a devastating complication following cardiac surgery. Pulmonary vein thrombi (PVT) are believed to be rare, but I have reported 37 cases of PVT in elderly patients with chest pain since 2012, indicating that PVT are not unusual.

Kidney Fibrosis In Vitro and In Vivo Models: Path Toward Physiologically Relevant Humanized Models
Advanced Healthcare Materials, Volume 14, Issue 9, April 4, 2025.This review discusses kidney diseases with a focus on kidney fibrosis and the models currently used. It highlights the limitations of animal and 2D in vitro models in replicating human kidney anatomy and physiology. Consequently, there is a significant need for humanized 3D in vitro models, such as 3D cell aggregates, membranes and hydrogels, on‐chip ...

Experimental Opacification of the Pulmonary Veins
Radiology, 1964 Angiography is of great value in the diagnosis and treatment of pulmonary disease. Celis (1) in 1946 described his technic of pulmonary angiography, and in 1951 angiographic findings in pulmonary disease were reported by D otter and Steinberg (2). Lyons (3) in 1957, after angiographic examination of over 600 patients with pulmonary disease, concluded ...

Advanced Healthcare Materials, EarlyView.Rod‐shaped particles outperform spherical particles of the same volume in preventing neutrophil infiltration to inflamed areas, both in vitro and in vivo. This therapeutic effectiveness is attributed to better cell targeting and decreased cell motility, resulting from the geometry‐driven phagocytosis and inhibited actin polymerization.
