Primary pulmonary artery tumors (PPATs), originating from the pulmonary artery intima, are rare tumors characterized by pulmonary artery luminal occlusion and pulmonary hypertension. Diagnosis of this rare entity is a challenging dilemma with the need for a high expertise in the radiological and pathological identification of PPATs. computed tomographic pulmonary angiography of PPATs may show filling defects, which are easily misdiagnosed. The radionuclide scan, along with other imaging examinations, can assist with the diagnosis, but the pathological diagnosis requires a puncture or surgical resection. Most primary pulmonary artery tumors are malignant, with poor prognosis and lack of specificity in clinical manifestations. However, there is no unified understanding and standard for diagnosis and treatment. In this review, we discuss the status, diagnosis, and treatment of primary pulmonary artery tumors, as well as how clinicians can better understand and treat the disease.

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.

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.

Aim: To investigate the relationship between epicardial adipose tissue (EAT) and myocardial strain and the severity of coronary artery disease (CAD), and to evaluate the predictive value of EAT parameters in early left ventricular (LV) diastolic dysfunction.
Materials And Methods: One hundred seventy patients with suspected CAD who underwent both coronary computed tomography angiography and echocardiography were enrolled in 2020. LV global strains were calculated using commercial software.

Fluid shear stress (FSS) from blood flow sensed by vascular endothelial cells (ECs) determines vessel behavior, but regulatory mechanisms are only partially understood. We used cell state transition assessment and regulation (cSTAR), a powerful computational method, to elucidate EC transcriptomic states under low shear stress (LSS), physiological shear stress (PSS), high shear stress (HSS), and oscillatory shear stress (OSS) that induce vessel inward remodeling, stabilization, outward remodeling, or disease susceptibility, respectively. Combined with a publicly available database on EC transcriptomic responses to drug treatments, this approach inferred a regulatory network controlling EC states and made several notable predictions.
