Article Abstract
Background: Aortic stiffness is a well-known cardio-vascular risk factor. For years, different methods have been studied in the assessment of aortic elastic properties and large arterial stiffness for risk stratification. Herein is an assessment of the role of intravascular ultrasound (IVUS) imaging for the evaluation of aortic elastic properties.
Methods: Intravascular ultrasound imaging of the aorta was performed in 12 patients with transthoracic echocardiography (TTE) and computed tomography (CT) evidence for enlargement of the ascending aorta - diameter ≥ 40.0 mm. Mechanical properties of the aorta were derived from the measured diameters and intra-aortic pressure. Paired samples T-test analyses were performed to determine differences between measurements derived by TTE, CT and IVUS.
Results: Mean values of the calculated elastic properties via IVUS of the ascending aorta were as follows: compliance 0.021 ± 0.02; strain 205 ± 4.3; aortic stiffness index 4.3 ± 0.75; elastic modulus 0.31 ± 0.05. On paired T-test analysis maximum ascending aortic diameter measured by CT aortography and IVUS did not differ significantly (t = -0.19, p = 0.985), but a significant difference between IVUS measurements and TTE derived diameters was found (t = 13.118, p = 0.034). On average, IVUS diameters were 2.3 mm larger than the results acquired by TTE (95% confidence interval: 14.21-17.13).
Conclusions: Intravascular ultrasound examination of the ascending aorta provided larger diameters than the ones collected by means of TTE. However, IVUS measurements did not differ significantly from diameters derived by CT aortography.

Sonographic examination of major vessels can be a valuable bedside tool for perioperative hemodynamic assessment. In the present review, we present the anatomic and physiological aspects of internal jugular vein ultrasonography, its utility in assessing central venous pressure, intravascular volume status, fluid responsiveness, and its predictive value regarding post-spinal anesthesia hypotension. The existing literature is primarily comprised of small, observational studies with great heterogeneity in their methodology and shortcomings in data development and analysis, rendering the generalization of their results difficult to interpret for daily clinical practice.

Background: An inward force is experienced by the guide catheter during device retrieval resulting in potential risk of deep engagement into the ostio-proximal coronary segment. This undesired movement can result in coronary injury. There is no systematic data or reports of techniques to prevent such inadvertent guide movement during difficult retrieval of devices.

Background: Cardiac issues following radiotherapy are increasingly prevalent among patients with thoracic cancer and coronary disease. However, the mechanisms underlying radiotherapy-induced plaque instability and changes in plaque characteristics on imaging remain unclear. This study used single-cell RNA sequencing to identify key features of vulnerable plaques following radiotherapy.

A 33-year-old male developed pulmonary vein (PV) stenosis 3 months after PV isolation for atrial fibrillation. Stents were implanted in the left superior and inferior PVs, but 2 years later, in-stent restenosis occurred. Intravascular ultrasound and nonobstructive general angioscopy (NOGA) revealed severe ostial stenosis and neointimal hyperplasia.
