Automatic pulmonary artery-vein separation in CT images using a twin-pipe network and topology reconstruction [PDF]

PeerJ Computer Science, 2023
Background With the wide application of CT scanning, the separation of pulmonary arteries and veins (A/V) based on CT images plays an important role for assisting surgeons in preoperative planning of lung cancer surgery.

Cardiovascular agents affect the tone of pulmonary arteries and veins in precision-cut lung slices.

PLoS ONE, 2011
IntroductionCardiovascular agents are pivotal in the therapy of heart failure. Apart from their action on ventricular contractility and systemic afterload, they affect pulmonary arteries and veins. Although these effects are crucial in heart failure with

Anomalous single pulmonary venous trunk

Avicenna Journal of Medicine, 2012
We present a rare case of a single pulmonary venous trunk that drains all pulmonary segments to the left atrium. This anomaly may mimic pulmonary arteriovenous malformation on imaging.

Bigeminal Pulmonary Vein Ectopy Suppressed by Pulmonary Vein Isolation

International Heart Journal, 2008
A 58-year-old man with atrial fibrillation underwent pulmonary vein (PV) isolation (PVI). Bigeminal atrial premature beats persisted from the beginning of the PVI. The cardiac recordings from a basket catheter (BC) revealed the PV ectopic origin in the distal right superior PV.

Snowman heart

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

Imaging of the pulmonary vasculature in congenital heart disease without gadolinium contrast: Intraindividual comparison of a novel Compressed SENSE accelerated 3D modified REACT with 4D contrast-enhanced magnetic resonance angiography

Journal of Cardiovascular Magnetic Resonance, 2020
Background Patients with Congenital heart disease (CHD) require repetitive imaging of the pulmonary vasculature throughout their life. In this study, we compared a novel Compressed SENSE accelerated (factor 9) electrocardiogram (ECG)- and respiratory ...
