CT angiography prior to endovascular aortic surgery is the standard non-invasive imaging method for evaluation of aortic dimensions and access sites. A detailed report is crucial to a proper planning. We assessed Artificial Intelligence (AI)-algorithm accuracy to measure vessels diameters at CT prior to transcatheter aortic valve implantation (TAVI). CT scans of 50 patients were included. Two Radiologists with experience in vascular imaging together manually assessed diameters at nine landmark positions according to the American Heart Association guidelines: 450 values were obtained. We implemented TOST (Two One-Sided Test) to determine whether the measurements were equivalent to the values obtained from the AI algorithm. When the equivalence bound was a range of ± 2 mm the test showed equivalence for every point; if the range was equal to ± 1 mm the two measurements were not equivalent in 6 points out of 9 (p-value > 0.05), close to the aortic valve. The time for automatic evaluation (average 1 min 47 s) was significantly lower compared with manual measurements (5 min 41 s) (p < 0.01). In conclusion, our results indicate that AI-algorithms can measure aortic diameters at CT prior to endovascular surgery with high accuracy. AI-assisted reporting promises high efficiency, reduced inter-reader variabilities and time saving. In order to perform optimal TAVI procedure planning aortic root analysis could be improved, including annulus dimensions.

Background: The personalized, free-breathing, heart rate-dependent computed tomography angiography (CTA) protocol can significantly reduce the utilization of contrast medium (CM). This proves especially beneficial for patients with chronic obstructive pulmonary disease (COPD) undergoing coronary artery CTA examinations.

Objective: The aim of this study was to evaluate the feasibility of a personalized CT scanning protocol that was tailored to patients' heart rate and free-breathing for coronary CTA of patients with COPD.

Article Synopsis
  • The study investigates the effectiveness of 3D virtual modeling (3DVM) and indocyanine green perfusion angiography (ICGPA) in improving surgical planning and outcomes during laparoscopic right hemicolectomy for colon cancer.
  • Advanced imaging techniques allowed for precise preoperative planning, showing a high correlation with intraoperative findings, which enabled better decisions regarding vessel management and anastomotic site selection.
  • The results indicate that using 3DVM and ICGPA not only enhances the surgical team’s ability to visualize vascular structures but also leads to successful surgeries without postoperative complications.

Assessment of bystander coronary artery disease in transcatheter aortic valve replacement (TAVR) patients using noncoronary-dedicated planning computed tomography angiography (CTA): diagnostic accuracy in a retrospective real-world cohort.

Department of Radiology, Division of General Radiology, Medical University of Graz, Auenbruggerplatz 9, 8036 Graz, Austria; Department of Radiology and Nuclear Medicine, University Hospital Wiener Neustadt, Corvinusring 3-5, 2700 Wiener Neustadt, Austria.

Aim: To assess the diagnostic potential of a noncoronary-dedicated pre-TAVR CT angiography (CTA) conducted as a prospective ECG-gated scan without premedication and standard cardiac reconstructions in evaluating bystander coronary artery disease (CAD) against invasive coronary angiography (ICA) as the gold standard.

Materials And Methods: This retrospective study included 232 patients who underwent both CTA and ICA as part of their pre-TAVR evaluation. Exclusion criteria included prior stent, pacemaker, coronary artery bypass, or valve surgery.

Catheter-related thrombosis (CRT) is a frequent and potentially serious complication associated with the widespread use of intravascular devices such as central venous catheters, including peripherally inserted central catheters and implantable port systems, pacemakers or implantable cardioverter-defibrillators. Although CRT management has been informed by guidelines extrapolated from lower extremity deep vein thrombosis (DVT), unique challenges remain due to the distinct anatomical, pathophysiological, and clinical characteristics of upper extremity DVT. Risk factors for CRT are multifactorial, encompassing patient-related characteristics such as cancer, prior venous thromboembolism, and infection, as well as catheter-specific factors like device type, lumens, and insertion site.
