Wireless blood pressure sensor implantation in sheep: A detailed technique

Animal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Admission Shock Index Is an Independent Predictor of In‐Hospital All‐Cause Mortality in Patients With Acute Aortic Dissection and Intramural Hematoma

Clinical Cardiology, Volume 49, Issue 5, May 2026.
An admission shock index (SI) ≥ 0.6 is a simple, rapid predictor of higher in‐hospital mortality in patients with acute aortic dissection and intramural hematoma. This early risk stratification tool is especially valuable for identifying high‐risk patients managed with conservative treatment.

Secondary Endoleak Management Following TEVAR and EVAR [PDF]

CardioVascular and Interventional Radiology, 2020
AbstractEndovascular abdominal and thoracic aortic aneurysm repair and are widely used to treat increasingly complex aneurysms. Secondary endoleaks, defined as those detected more than 30 days after the procedure and after previous negative imaging, remain a challenge for aortic specialists, conferring a need for long-term surveillance and ...

Mixed Reality‐Assisted Thoracic Endovascular Aortic Repair: A Retrospective Study on Efficacy and Safety

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
This study demonstrates the significant clinical utility of Mixed Reality (MR) in Thoracic Endovascular Aortic Repair (TEVAR). Our findings reveal that MR‐assisted workflows enhance patient comprehension and satisfaction preoperatively and provide intuitive intraoperative navigation.

Adverse Hemodynamics in Kommerell's Diverticulum: A Comparative Case Report Linking Oscillatory Shear Index to Aortic Dissection

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Hemodynamic evaluation using four‐dimensional flow magnetic resonance imaging or computational fluid dynamics can identify a high‐risk phenotype in Kommerell's diverticulum, which is characterized by intradiverticular vortex formation, low wall shear stress, and elevated oscillatory shear index (OSI).

Stent-Graft Migration Post-Endovascular Repair of Thoracic Aorta: A Retrospective Cohort Study

Indian Journal of Radiology and Imaging, 2022
Background Migration of the stent-graft post-thoracic endovascular aortic repair (TEVAR) is not uncommon; however, it is sparsely reported. The objective of this study was to assess the incidence, risk factors, and complications of stent-graft migration ...
