Evaluating Pulmonary Vein Isolation [PDF]

Journal of Arrhythmia, 2008
AbstractPulmonary vein isolation is the electrophysiological endpoint of complete conduction block at the level of the veno‐atrial junction and must be explicitly distinguished from encircling PV ablation which frequently does not result in isolation.The prerequisites for successful PV isolation include a knowledge of the individual anatomy of the PVs ...

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.

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

Arterialization of Central Pulmonary Vein

Journal of the American College of Cardiology, 2011
, Online Figs. 3 to 5, Online Video 1) revealed uniform nar-rowing of the central vein with severe ostial stenosis. Central pulmonary-vein obstruction isknown to trigger progressive medial hypertrophy and intimal fibrosis of the affected venoustree (1). Gradually, venous pressure and waveform arterialize.

Iron‐MOFs for Biomedical Applications

Advanced Healthcare Materials, Volume 14, Issue 8, March 25, 2025.
This review introduces the unique properties of iron‐based metal–organic frameworks (Fe‐MOFs), the advances in synthesis and formulation, and their state‐of‐the‐art applications in biomedicine. It discusses the challenges in transitioning Fe‐MOFs from research to clinical use, emphasizing the need for eco‐friendly production methods, and a deeper ...

Pulmonary vein thrombosis in patients with medical risk factors

Radiology Case Reports, 2018
Pulmonary vein thrombosis in patients with medical illnesses has been rarely reported, and it is also rarely reported in those with no risk factors. We report 2 patients with pulmonary vein thrombosis, 1 with metastatic renal cell carcinoma and 1 with ...

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 ...

Pulmonary Vein Nonconduction

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.
