Errors in pulmonary vein identification and ostia location in the absence of pulmonary vein imaging

, 2005
Background: A key point in atrial fibrillation (AF) ablation is the ability to identify the pulmonary vein (PVs) and locate their ostia. Objectives: The purpose of this study was to assess the error margin of PV identification and ostia location in the ...

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Dual-drainage pulmonary venous return of the left upper lobe

Annals of Pediatric Cardiology
Dual drainage of a pulmonary vein is an unusual anomaly of pulmonary venous drainage. While being evaluated for hypertension, a child was found with dual drainage of the upper left lobe through a vertical vein that connects to the normal pulmonary vein ...

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 ...

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

Advanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

Cryoballoon Pulmonary Vein Isolation with Real‐Time Recordings from the Pulmonary Veins [PDF]

Journal of Cardiovascular Electrophysiology, 2009
Introduction: Cryoballoon (CB) ablation represents a novel technology for pulmonary vein isolation (PVI). We investigated feasibility and safety of CB‐PVI, utilizing a novel spiral catheter (SC), thereby obtaining real‐time PV potential registration.

The fifth pulmonary vein

, 2016
A cadaver in Myungsung Medical College (MMC) had a 3rd pulmonary vein originating from the middle lobe of the right lung. Such anatomical variations are very rare. People with this variation have a total of five pulmonary veins entering left atrium.

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC

Advanced Science, EarlyView.
CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,
