Background: Abnormal blood flow patterns are known to contribute to the ascending aortic dilation in patients with bicuspid aortic valve (BAV). The present study elucidated the blood flow characteristics in the dilated ascending aorta before and after transcatheter aortic valve replacement (TAVR) using computational fluid dynamics (CFD) analysis.
Methods: We performed CFD analysis in three BAV patients with ascending aortic dilation (maximum diameter ≥ 45 mm) who underwent TAVR.

Objective: To demonstrate successful treatment of a patient with aneurysmal lesions of several aortic segments.
Material And Methods: A patient with myelodysplastic syndrome and pancytopenia underwent endovascular repair for abdominal aortic aneurysm. Aneurysm of common iliac artery and borderline thoracic aortic aneurysm occurred 2 years after surgery.

Article Synopsis
- This study evaluated the effectiveness of dual-source CT with volumetric measurement for monitoring patients with Stanford Type B aortic dissection after intrathoracic aortic repair (TEVAR).
- It followed 40 patients at 3, 6, and 12 months post-surgery, measuring the diameters, areas, and volumes of the true and false lumens in various sections of the aorta.
- Results showed significant changes in the measurements, indicating that volumetric assessment is a more accurate way to gauge the remodeling of aortic dissection compared to just using diameter and area measurements.

Current guidelines recommend that surveillance imaging should be performed at least every third year for patients with ascending thoracic aortic aneurysm (ATAA) even though such aneurysms' growth rate is mostly minimal. The purpose of this study was to clarify the pattern of the growth of ATAAs in a real-life patient population to adjust the optimal timing of aortic surveillance for each patient. This study includes patients ( = 209) who had been followed due to ATAA in the central hospital of North Karelia in Eastern Finland between years 2007 and 2023.

A 14-year-old child with recurrent cyanotic spells at the age of 9 months underwent echocardiography at that time, which revealed tetralogy of Fallot (TOF). Follow-up computed tomography angiography revealed TOF with valvular pulmonary stenosis and a right-sided aortic arch with mirror image branching. Interestingly, an unusual anomalous course of the left brachiocephalic vein was seen.
