This study was undertaken to assess the accuracy of computerized tomographic angiography (CTA) for the evaluation of renal vascular anatomy for pre-operative donor assessment in living kidney transplantation and to compare it with conventional angiography. CTA of 70 living donor kidney donors were analyzed by two blinded observers and compared with the intraoperative findings. Similarly, findings of formal angiography of 30 living donor kidney donors were compared with the intraoperative observations. In the CTA group, there were two patients each with two main renal veins discovered during surgery that had not been recorded on CTA. In the second group, there was one patient with unrevealed two main renal veins before surgery. In both groups, accessory renal arteries were diagnosed. Overall, the accuracy for renal main artery anatomy was 100% for both CTA and conventional angiography. Accuracy for renal main vein anatomy was 97.1% and 96.6% for CTA and conventional angiography, respectively. Hence, these two modalities had comparable results for assessment of main renal vasculature anatomy.

Composite cardiac computed tomography angiography score for improved risk assessment in chronic coronary syndromes.

Agatston score, the degree of lumen narrowing categorized by CAD-RADS, high-risk atherosclerotic plaque features and pericoronary adipose tissue attenuation (PCAT) are parameters, which can be assessed non-invasively by coronary computed tomography angiography (CCTA) and aid risk stratification in patients with chronic coronary syndromes (CCS). However, few studies have so far compared the prognostic value of all those parameters together. To develop and test the prognostic value of a composite CCTA score, derived from Agatston score, CAD-RADS, high-risk plaques and PCAT in patients undergoing CCTA due to CCS.

Objectives: This study aims to investigate the relationship between ABO blood groups and the severity of Peripheral Artery Disease (PAD) lesions, the coexistence of Coronary Artery Disease (CAD) with PAD, and to identify which blood groups may be more predisposed to these conditions.
Methods: This study, which has a single-center and retrospective design, includes 305 patients diagnosed with Peripheral Artery Disease (PAD) between 2015 and 2021. The patients were selected from those with at least 50% stenosis detected by computed tomography (CT) angiography.

Fractional flow reserve (FFR) has been well validated as a modality for evaluating myocardial ischemia, demonstrating the superiority of FFR-guided percutaneous coronary intervention (PCI) over conventional angiography-guided PCI. As a result, the strategy for coronary artery bypass grafting (CABG) is shifting toward FFR guidance. However, the advantage of FFR-guided CABG over angiography-guided CABG remains unclear.

Purpose: To report the clinical presentation and follow-up, including the optical coherence tomography, angiography and electrophysiology of two individuals from the same family presenting with an isolated retinal dystrophy and optic nerve edema who were diagnosed with ROSAH-like syndrome.
Method: Observational case report of a 55-year-old woman and her 36-year-old son with a genetic analysis of ROSAH, after a long-term follow-up.
Results: Both the mother and her son displayed severe optic nerve infiltration and retinal pigment atrophy with intraocular inflammation, which were not improved by immunosuppressive treatment.

Pulmonary thromboembolism (PTE) is the third most common cause of acute cardiovascular disease, which can lead to high morbidity and mortality if left untreated. Anatomical and electrophysiological variations and obesity may complicate timely diagnosis and delay required management. While computed tomography pulmonary angiography (CTPA) remains the most accurate diagnostic tool, initial assessments using electrocardiography (ECG) or echocardiography can be helpful in early suspicion.
