Cardiac parasympathetic modulation in the setting of radiofrequency ablation for atrial fibrillation
Archives of Medical Science, 2019 The cardiac autonomic nervous system plays an important role in the genesis and maintenance of atrial fibrillation. Although, pulmonary vein isolation is the cornerstone in today’s approach to atrial fibrillation ablation, a considerable proportion of ...

Histological Study of the Left Atrial Wall: A Consideration of the Compound Myocardial Architecture and Potential Durability with Respect to Catheter Ablation in Pulmonary Vein Isolation Procedures [PDF]
, 2010 Pulmonary vein isolation using radiofrequency energy is performed extensively to treat symptomatic, drug-refractory atrial fibrillation. However, anatomical knowledge of the left atrial wall surrounding the pulmonary vein (PV) openings is insufficient to

Learning Tubule-Sensitive CNNs for Pulmonary Airway and Artery-Vein Segmentation in CT [PDF]
arXiv, 2020 Training convolutional neural networks (CNNs) for segmentation of pulmonary airway, artery, and vein is challenging due to sparse supervisory signals caused by the severe class imbalance between tubular targets and background. We present a CNNs-based method for accurate airway and artery-vein segmentation in non-contrast computed tomography.

Isolated agenesis of the right pulmonary veins with pulmonary sequestration
Annals of Pediatric Cardiology, 2019 We report two cases of agenesis of the right pulmonary veins (PVs) associated with sequestration of the right lung with systemic to pulmonary collateral. Both the children were referred for evaluation of recurrent lower respiratory tract infections. Transthoracic echocardiographic evaluation showed reversal of flow in the right pulmonary artery (PA ...

Advanced Materials Technologies, Volume 10, Issue 7, April 4, 2025.The concept of “green” vessels explores naturally derived tubular structures from three decellularized plants—Water Spinach, Green Onion, and Water Horsetail—as innovative alternatives for vessel models and vascular grafts. Microstructural and mechanical testing reveal the promising suturability and mechanical properties of Water Spinach.

Application and reduction of a nonlinear hyperelastic wall model capturing ex vivo relationships between fluid pressure, area and wall thickness in normal and hypertensive murine left pulmonary arteries [PDF]
arXiv, 2022 Pulmonary hypertension is a cardiovascular disorder manifested by elevated arterial blood pressure together with vessel wall stiffening and thickening due to alterations in collagen, elastin and smooth muscle cells. Hypoxia-induced (type 3) pulmonary hypertension can be studied in animals exposed to a low oxygen environment for prolonged time periods ...

Advanced Therapeutics, Volume 8, Issue 4, April 2025.This study investigates the combination of host‐directed therapeutics (HDT) with antibiotics in a single polymeric micelle based on polypept(o)ides for the therapy of Mycobacterium tuberculosis (Mtb) and ‐marinum (Mm) infections. When the HDT and antibiotic are co‐encapsulated, it significantly reduces bacterial burden in cells and improves overall ...

A Case With Pulmonary Vein Stenosis and Obstruction After Pulmonary Vein Isolation
JACC: Clinical Electrophysiology, 2018 Pulmonary vein stenosis and occlusion are some of the major complications after radiofrequency ablation of atrial fibrillation. The prevalence of pulmonary vein stenosis and pulmonary vein occlusion decreased remarkably after the advent of area circumferential ablation and antral isolation ...
