Case Report: Double-Decker Repair of Partial Pulmonary Venous Return Into the Coronary Sinus

Frontiers in Cardiovascular Medicine, 2022
We present a case of persistent left superior vena cava (LSVC) draining into the right atrium (RA) via the coronary sinus (CS), while the left superior pulmonary vein returns abnormally to the CS.

Prediction of need for bowel resection in acute superior mesenteric artery occlusion: A retrospective study of 48 Japanese patients

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 175-181, January 2023., 2023
In a study of 48 patients with acute superior mesenteric artery occlusion, a logistic regression model using time from onset to diagnosis and the occlusion site of superior mesenteric artery showed 78.6% sensitivity in ruling out cases requiring bowel resection.

Semi-supervised Left Atrium Segmentation with Mutual Consistency Training [PDF]

arXiv, 2021
Semi-supervised learning has attracted great attention in the field of machine learning, especially for medical image segmentation tasks, since it alleviates the heavy burden of collecting abundant densely annotated data for training. However, most of existing methods underestimate the importance of challenging regions (e.g.

Non-invasive estimation of left atrial dominant frequency in atrial fibrillation from different electrode sites: Insight from body surface potential mapping [PDF]

, 2014
© 2014, CardioFront LLC. All rights reserved. The dominant driving sources of atrial fibrillation are often found in the left atrium, but the expression of left atrial activation on the body surface is poorly understood.

Bruton tyrosine kinase inhibitors in the management of Waldenström macroglobulinemia

American Journal of Hematology, Volume 98, Issue 2, Page 338-347, February 2023., 2023
Abstract Bruton tyrosine kinase (BTK) inhibitors have taken a central role in the management of patients with Waldenström macroglobulinemia and are the only agents approved by the Food and Drug Administration (FDA) to treat these patients. Although associated with high rates of durable responses, unmet needs with BTK inhibitor therapy include ...

Anatomic Study of Number of Pulmonary Veins Draining into the Left Atrium and Their Variations

Journal of Medical Sciences and Health, 2020
Introduction: Pulmonary veins originate from the alveolar capillary plexus and carry oxygenated blood to the left atrium. The fibrous pericardium is perforated by the pulmonary veins and they drain separately in the posterosuperior aspect of the left ...

Birth defects associated with paternal firefighting in the National Birth Defects Prevention Study

American Journal of Industrial Medicine, Volume 66, Issue 1, Page 30-40, January 2023., 2023
Abstract Background Few studies have evaluated birth defects among children of firefighters. We investigated associations between birth defects and paternal work as a firefighter compared to work in non‐firefighting and police officer occupations. Methods We analyzed 1997–2011 data from the multi‐site case‐control National Birth Defects Prevention ...
