A novel rat model of pulmonary artery embolism and the application value of lung ultrasound B‐lines in early‐stage pulmonary embolism

open access: yesAnimal Models and Experimental Medicine, EarlyView.
We report a novel embolus‐induced PE rat model prepared via the inferior vena cava under ultrasound guidance. The embolus employed featured a tubular plastic casing filled with thrombus. By minimizing the contact surface between plasmin and thrombus, it effectively restrains the elevated plasmin activity in rats.

The Impact of Aging on the Anatomical Course of the Azygos Vein: A Retrospective, Computed Tomography Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The azygos vein (AV) is typically described as ascending vertically to the right of the vertebral column before arching anteriorly to drain into the superior vena cava. However, a small number of studies suggest that it is found leftward in older adults.

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

The Impact of a Visualized Steerable Sheath on Radiofrequency Catheter Ablation for First‐Time Atrial Fibrillation Ablation: A Prospective, Randomized, Single‐Blind Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background A 3D electroanatomical mapping (3D‐EAM) visualized steerable sheath was designed to improve catheter placement and reduce radiation exposure during ablation, an established treatment for atrial fibrillation (AF). However, prospective randomized data comparing the procedural and clinical outcomes of visualized and non‐visualized ...

Disappearing Inferior Vena Cava in A Pediatric Patient with Down Syndrome and Hereditary Thrombophilia

open access: yesJournal of the Belgian Society of Radiology, 2016
Absence of the infrarenal segment of the inferior vena cava is an extremely rare anomaly. The reasons for such a developmental failure are unclear. Most researchers believe that the cause lies in embryonic dysgenesis affecting separate segments or the ...

MELD score predicts outcomes in patients with advanced heart failure: A longitudinal evaluation

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 839-847, April 2025.
Abstract Aims Advanced heart failure (AHF) is characterized by recurrent episodes of haemodynamic instability and frequent hospitalizations, leading to a progressive decline in quality of life and high mortality rates. The objectives of this study were to evaluate the effect of the model for end‐stage liver disease (MELD) score and its variations in ...

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...

Transitional Cell Carcinoma of the Renal Pelvis with Extension into the Inferior Vena Cava: A Report of Two Cases

open access: yesKaohsiung Journal of Medical Sciences, 2003
Of all primary malignant renal tumors, 10% to 15% originate from the renal pelvis, and 90% to 92% of these tumors are transitional cell carcinomas. Nonetheless, renal pelvis transitional cell carcinoma extending into the inferior vena cava is very rare ...

Inferior vena cava filters

open access: yesCanadian Medical Association Journal, 2015
Under fluoroscopic guidance, IVC filters are placed percutaneously via the jugular or femoral vein. Current guidelines recommend use in patients with known venous thromboembolism who have an absolute contraindication to anticoagulant therapy (e.g., patients with hemorrhagic stroke or ...

Prognostic role of TAPSE to PASP ratio in outpatients with left ventricular systolic dysfunction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 912-922, April 2025.
Abstract Aims Few data are available regarding the role of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), a measurement of right ventricular to pulmonary artery coupling, in patients with chronic heart failure and left ventricular systolic dysfunction.
