AI Article Synopsis

  • Pulmonary vascular remodeling is a key feature of pulmonary hypertension (PH), leading to structural changes in the blood vessel layers, including the intima, media, and adventitia.
  • It involves the growth and transformation of pulmonary artery cells, specifically endothelial and smooth muscle cells, along with the interaction of other cell types like fibroblasts and components of the extracellular matrix.
  • Various factors, including inflammation and cell death, contribute to these changes, and the article discusses the mechanisms that drive the progression of the disease.

Article Abstract

Pulmonary vascular remodeling is the critical structural alteration and pathological feature in pulmonary hypertension (PH) and involves changes in the intima, media and adventitia. Pulmonary vascular remodeling consists of the proliferation and phenotypic transformation of pulmonary artery endothelial cells (PAECs) and pulmonary artery smooth muscle cells (PASMCs) of the middle membranous pulmonary artery, as well as complex interactions involving external layer pulmonary artery fibroblasts (PAFs) and extracellular matrix (ECM). Inflammatory mechanisms, apoptosis and other factors in the vascular wall are influenced by different mechanisms that likely act in concert to drive disease progression. This article reviews these pathological changes and highlights some pathogenetic mechanisms involved in the remodeling process.

The implication of pericardial effusion in the third trimester for preeclampsia and heart failure in high-risk pregnant women.

J Echocardiogr

Division of Cardiology, Department of Internal Medicine, Keimyung University Dongsan Medical Center, Keimyung University School of Medicine, 1035 Dalgubeol-Daero, Dalseo-Gu, Daegu, 42601, Republic of Korea.

Background: With the growing number of high-risk pregnant women, echocardiography frequently reveals pericardial effusion (PE). However, the clinical implications of PE are unknown.

Method: We analyzed a cohort of 406 high-risk pregnant women who underwent echocardiography in the third trimester between November 2019 and December 2022.

We sought to evaluate the intracardiac morphology and associated cardiovascular anomalies in patients with double inlet right ventricle (DIRV) on multidetector CT angiography. A retrospective search of our departmental database was conducted from January 2014 to January 2023 to identify patients with a diagnosis of DIRV on CT angiography. The intracardiac anatomy and associated cardiovascular abnormalities were systematically evaluated.

Background: Anomalous systemic artery to the left lower lobe (ASALLL) is a rare congenital anomaly. The primary symptoms include hemoptysis and lung infection, though some patients may remain asymptomatic. Currently, there is no consensus on the indications for treatment or the optimal choice of therapy for this condition.

Background: Pulmonary artery sling (PAS) is a rare congenital anomaly where the left pulmonary artery (LPA) branches from the right pulmonary artery, compressing the trachea and esophagus and frequently leading to respiratory distress in infants. Surgical intervention, such as LPA reimplantation or translocation, is crucial to relieve airway compression and restore normal pulmonary function.

Case Presentation: This report highlights varied LPA anatomies, including a unique case of an anomalous LPA without true sling formation but causing tracheal compression, alongside two typical PAS cases.

Targeting Fibroblast Activation Protein for Molecular Imaging of Fibrotic Remodeling in Pulmonary Arterial Hypertension.

J Nucl Med

January 2025

Department of Pulmonary and Critical Care Medicine, First Affiliated Hospital of Guangzhou Medical University, Guangzhou Institute of Respiratory Health, State Key Laboratory of Respiratory Disease, National Clinical Research Center for Respiratory Disease, Guangzhou, China; and

The purpose of this study was to investigate the feasibility of using F-labeled fibroblast activation protein inhibitor (FAPI) PET/CT in assessing the fibrotic remodeling of the pulmonary artery (PA) and the right ventricle (RV) in pulmonary arterial hypertension (PAH). In a rat model of monocrotaline-induced PAH, rats were euthanized at different time points for tissue analysis (fibroblast activation protein immunofluorescence and Masson's trichrome staining) after completing F-FAPI PET/CT and hemodynamic measurements. Thirty-eight PAH patients were enrolled to participate in F-FAPI PET/CT imaging, with right heart catheterization and echocardiography performed within 1 wk to assess pulmonary hemodynamics and cardiac function.
