Abstract
We aimed to test whether computed tomography (CT)-diagnosed Non-Alcoholic Fatty Liver Disease (NAFLD) is a risk factor for cerebrovascular symptoms in patients with suspected atherosclerotic disease. A total of 550 patients (mean age 65.2 ± 8.8 years, 370 males) with carotid plaques who underwent carotid computed tomographic angiography (CTA) and unenhanced abdominal CT were retrospectively analyzed. NAFLD was diagnosed by abdominal CT. Carotid CTA assessed the presence of carotid artery stenosis or plaque. The relationship between NAFLD and cerebrovascular symptoms was analyzed using generalized estimating equations and receiver operating characteristic (ROC) analysis. The prevalence of NAFLD was significantly higher in symptomatic patients (76.5 vs 9.8%; P < .001). After adjusting for several confounding factors (e.g., hypertension and hyperlipidemia), univariate and multivariate logic regression analysis revealed that NAFLD was still strongly associated with cerebrovascular symptoms (odds ratio, 22.81; 95% CI 13.03-39.93; P < .001). ROC analysis showed that the area under the curve for discriminating symptomatic and asymptomatic plaques using NAFLD measurements was 0.833, with a sensitivity of 76.5% and a specificity of 90.2%. NAFLD is strongly associated with an increased risk of cerebrovascular symptoms. It may be an important predictor of symptomatic carotid plaque and cerebrovascular symptoms.

Abstract
Absence of periprocedural visualization of three-dimensional (3D) left heart anatomy and its surrounding structures in fluoroscopy may reduce the rate of successful transcatheter mitral valve repair. We proposed a multimodal imaging strategy based on 3D computed tomography (CT) angiography and 3D cone beam CT fusion images, which enabled real-time visual inspection of 3D cardiac structures on fluoroscopy, to optimize transcatheter mitral intervention. This new image fusion technology, together with standard transesophageal echocardiography guidance, improved the efficiency and safety of the procedure, and could be considered as a new workflow for transcatheter mitral valve intervention.

Abstract
OBJECTIVE In many studies on aortic disease, women are underrepresented. The present study aims to assess sex-specific morphometric differences and gain more insight into endovascular treatment of the ascending aorta (AA) and arch. METHODS Electrocardiogram-gated cardiac computed tomography scans of 116 consecutive patients who were evaluated for transcatheter aortic valve replacement were retrospectively reviewed. Measurements of the AA and aortic arch were made in multiplanar views, perpendicular to the semi-automatic centerline. Multiple linear regression analysis was performed to identify predictors affecting AA and aortic arch diameter in men and women. Propensity score matching was used to investigate whether sex influences aortic morphology. RESULTS In both sexes, body surface area (BSA) was identified as a positive predictor and diabetes as a negative predictor for aortic diameters. In men, age was identified as a positive predictor and smoking as a negative predictor for aortic diameters. Propensity score matching identified 40 pairs. Systolic and diastolic mean diameters and AA length were significantly wider in men. On average, male aortas were 7.4% wider than female aortas, both in systole and diastole. CONCLUSIONS The present analysis demonstrates that, in women, increased BSA is associated with increased aortic arch diameters, while diabetes is associated with decreased AA and arch diameters. In men, increased BSA and age are associated with increased AA and arch diameters, while smoking and diabetes are associated with decreased AA and arch diameters. Men were confirmed to have 7.4% greater AA and arch diameters than women. CLINICAL IMPACT Men had 7.4% greater ascending aorta and arch diameters than women in a retrospective cohort, gated computed tomography-based study of 116 patients. Sex-specific differences in ascending aortic and arch size should be considered by aortic endovascular device manufacturers and physicians when developing ascending and arch endografts and planning aortic interventions.

Abstract
Vasculitis is the inflammatory changes in vessels of any size that usually have a systemic involvement with a quite variable clinical presentation affecting various organs. Although systemic presentation is more common, in some cases localized inflammation of vasculature of a single organ or limited branches of aorta are reported. Here we present, an isolated vasculitis of bilateral inferior thyroidal arteries in a female patient aged 49 years, who presented with neck pain and was diagnosed with ultrasonography and computed tomographic angiography. The clinical and imaging findings were managed successfully with glucocorticoid induction and addition of methotrexate to the treatment. Localized forms of vasculitis are rarer and the limited size of the affected area makes diagnostic investigations and management more complicated. Non-invasive imaging modalities rather than conventional angiography provide useful information in a safer and easier way. Isolated vasculitis of thyroidal arteries is an extremely uncommon site and should be excluded in case of unexplained neck pain, even in the presence of normal laboratory examinations, probably because of the size of the involved vessels.

Abstract
Takayasu arteritis (TA) is an autoimmune vasculitis with unknown etiology. It can have varied presentations ranging from nonspecific symptoms to florid vasculitic symptoms. Awareness of the complications of this disease is also vital in managing patients who are already diagnosed with TA. We present the interesting case of a middle-aged woman, diagnosed case of TA who presented with an acute pulmonary embolism masquerading as an acute lower respiratory infection. Delayed diagnosis or misdiagnosis of acute major thromboembolism can be fatal. There needs to be a high index of suspicion from the clinician's end to reach a diagnosis and prompt intervention.

Abstract
PURPOSE Endoleaks are a common complication after endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR). The detection and correct classification of endoleaks is essential for the further treatment of affected patients. However, standard computed tomography angiography (CTA) provides no hemodynamic information on endoleaks, which can result in misclassification in complex cases. The aim of this study was to compare standard CTA (sCTA) with dynamic, dual-energy CTA (dCTA) for detection and classification of endoleaks following EVAR or TEVAR. MATERIALS AND METHODS This retrospective evaluation compared 69 sCTA diagnostic examinations performed on 50 different patients with 89 dCTA diagnostic examinations performed on 69 different patients. RESULTS In total, 15.9% of sCTA examinations and 49.4% of dCTA examinations led to the detection of endoleaks. With sCTA, 20.0% of patients were diagnosed with endoleaks, while with dCTA, 37.7% of patients were diagnosed with endoleaks. With sCTA, mainly Type 1 endoleaks were detected, whereas, with dCTA, the types of detected endoleaks were more evenly distributed. In comparison with the literature, the frequencies of endoleak types detected with dCTA better reflect the natural distribution than the frequencies detected with standard CTA. CONCLUSION Based on the retrospective comparative evaluation, dCTA could pose a valuable supplementary diagnostic tool resulting in a more accurate and realistic detection and classification of suspected endoleaks.

Abstract
Introduction Revision total hip arthroplasty requires meticulous planning and execution to achieve the desired outcome. Pelvic vessel injury following total hip arthroplasty is rare, but a well-known and serious complication, having a very high morbidity (15%) and mortality (7%). This case demonstrates the rare occurrence of acetabular screw abutment to the external iliac vessels, which if removed during revision hip surgery without releasing the adhesions around it, will lead to avulsion injury of the vessels and a catastrophic event. Case Report We present this challenging and unique case of a 64-year-old female patient where the acetabular component screw was found to be adherent to the external iliac vessels, with vascular injury imminent. During revision surgery, the iliac vessels were first released free of all adhesions with the intrapelvis screw using an ilioinguinal incision and retroperitoneal approach. The prosthesis was removed using a posterior approach to the hip joint. Definitive surgery was performed after 2 weeks. Conclusion Surgeons should be cognizant of the possibility of an avulsion vascular injury in revision cases having intrapelvic screws or implants. The proximity of such an implant with the intrapelvic vasculature must be confirmed preoperatively. Management should be individualized. Dual approach and staged procedure help in a favorable outcome. Vascular injury, revision total hip arthroplasty, screw abutting iliac vessel, external iliac vessel, computed tomographic angiography.

Abstract
AIM We aimed to explore the application of computed tomographic angiography (CTA) and echocardiography in predicting left atrial appendage (LAA) thrombosis in patients with non-valvular atrial fibrillation. METHODS The clinical data of 164 atrial fibrillation patients receiving cardiac CTA and real-time three-dimensional transoesophageal echocardiography (RT-3D-TEE) were retrospectively analysed. The patients were divided into group A (anticoagulant treatment group, n = 112) and group B (selective anticoagulant treatment group, n = 52) according to the CHA2DS2-VASc score, which scored for the presence or absence of congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke/transient ischaemic attack, vascular disease, age 65-74 years and gender (female). The CHA2DS2-VASc score was used to predict risk of thromboembolism from atrial fibrillation. The correlations of CHA2DS2-VASc score with CTA-based LAA classification and RT-3D-TEE measurement parameters were explored using Spearman's analysis. Receiver operating characteristic (ROC) curves were plotted to explore the predictive value of CTA and RT-3D-TEE for LAA thrombus. RESULTS There were significant differences in age, disease course, hypertension, diabetes mellitus, coronary heart disease, heart failure, stroke/transient ischaemic attack/thromboembolism, vascular disease, B-type natriuretic peptide and serum uric acid levels, CHA2DS2-VASc score, LAA classification, left ventricular ejection fraction (LVEF), left atrial diameter (LAD), maximum diameter of LAA orifice, minimum diameter of LAA orifice and LAA length (p < 0.05). CHA2DS2- VASc score was positively correlated with cauliflower LAA, LAD, maximum diameter of LAA orifice, minimum diameter of LAA orifice and LAA length, and negatively correlated with LVEF (p < 0.001). ROC curve analysis indicated that CTA, RT-3D-TEE and CHA2DS2-VASc score had similar predictive values for risk of LAA thrombosis in atrial fibrillation patients, with the areas under the curve being 0.778, 0.814 and 0.792, respectively. CONCLUSIONS Both CTA and RT-3D-TEE had high predictive values for LAA thrombosis in atrial fibrillation patients.

Abstract
Introduction Following subarachnoid hemorrhage, cerebral vasospasm is the primary cause of morbidity and death. The aim of this study is to predict the development of vasospasm by detecting changes in vessel diameter after surgery using computed tomography angiography. Methods We retrospectively evaluated the patients who underwent aneurysm clipping due to a bleeding aneurysm between 2019-2022. Age, gender, location, subarachnoid hemorrhage grades, development of perioperative rupture, and temporary clip use were examined. Preoperative and postoperative diameters of the internal carotid artery, A1-A2, and M1-M2 were measured. Radiological and clinical vasospasm development in the postoperative period was also documented. Results The aneurysm localizations of the 100 patients (mean age: 50.38±13.04 years) were anterior cerebral artery in 50 patients, internal carotid artery in 37 patients, and middle cerebral artery in 30 patients. In the postoperative follow-up, radiological vasospasm was apparent in 41 patients. The changes in arterial diameter reveal a statistically significant decrease in the internal carotid artery, M1-M2, and A1-A2 artery diameters on the operated side compared to the contralateral side (p<0.001). Based on the receiver operating characteristic (ROC) analysis, the most likely change in arterial diameter on the operated side to indicate the presence of vasospasm was calculated from the available data, where the decrease in total arterial diameter was 13.7%. Conclusion Vasospasm remains one of the significant causes of morbidity and mortality post subarachnoid hemorrhage. While there have been advances in imaging modalities, predicting which patients will develop vasospasm has remained elusive. Our research attempts to provide a quantifiable metric (13.7% decrease in vessel diameter) that can be an early predictor of this complication.

Abstract
Background This study aimed, first, to angiographically investigate and analyze prostatic artery (PA) origin in a Greek male population with benign prostatic hyperplasia (BPH) treated with prostatic artery embolization (PAE) and, second, to correlate prostatic arterial anatomy with technical and clinical aspects of PAE. Methodology This was a retrospective study of BPH patients who underwent PAE in a single tertiary center in Greece from June 2019 to July 2022. For the first part of the study, PA was imaged with computed tomography angiography (CTA) before PAE and with digital subtraction angiography (DSA) during PAE in all patients. A widely accepted system for the classification of PA origin was applied. Type I, a common origin of PA and superior vesical artery (SVA) from the anterior division of internal iliac artery (IIA). Type II, PA originating from the anterior division of IIA, separate from, and inferior to SVA. Type III, the origin of PA from the obturator artery. Type IV, the origin of PA from the internal pudendal artery. Type V, rarer origins of PA. For the second part of the study, a subgroup of patients from the first part (treated with the same PAE protocol and free of vascular pathology that could have interfered with the technical success of PAE) was selected. In this subgroup, differences in PA origin were correlated with technical aspects (feasibility of catheterization of PA, fluoroscopy time (FT), dose area product (DAP)) and clinical outcomes of PAE. Results After the exclusion of four patients, 159 patients were included in the first part of the study. From a total of 355 PAs, 110 (31%) were compatible with type I, 58 (16.3%) type II, 45 (12.7%) type III, 110 (31%) type IV, and 32 (9%) type V. PA origin from an accessory internal pudendal artery was the most common among the rare origins of type V. Regarding the second part of the study (a subgroup of 101 patients selected to facilitate comparisons between the different types of PA origin), type I was associated with significantly more incidences of failed or difficult catheterization of the PA compared to all other types combined (27/64 vs. 18/138, p < 0.001). Types III, IV, and V showed a relatively low degree of technical difficulty. Patients with type I PA origin of at least one pelvic side (subgroup (I), n = 48) had significantly longer FT and DAP compared to the rest (subgroup (O), n = 53). Clinical success rates of PAE were slightly lower for the subgroup (I), although the difference was not statistically significant (75.8% vs. 83.8% at 18 months post-PAE, p = 0.137). No major complications were observed. Conclusions This is the first study of PA origin in Greece. It was demonstrated that types I and IV of PA origin were the most common and had the same prevalence. Type I showed significantly higher technical difficulty compared to the others, but had no significant impact on the clinical outcomes of PAE.

Abstract
OBJECTIVE To evaluate the effect of low tube voltage (100 kV) combined with adaptive statistical iterative reconstruction-V (ASIR-V) on the visualization and image quality of the Adamkiewicz artery (AKA). METHODS One hundred patients were prospectively enrolled and randomly assigned into two groups (both n = 50). Group A (100 kV) was reconstructed with filtered back projection (FBP) and ASIR-V from 10% to 100% with 10% intervals. Group B (120 kV) was only reconstructed with FBP. The objective image quality was evaluated by using CT values of the aorta (CTAorta), background noise, signal-to-noise ratio of the descending aorta (SNRAorta), and contrast-to-noise ratio of the spinal cord (CNRSpinal cord). The subjective image quality and visualization scores of the AKA were assessed on a 5-point scale. RESULTS CTAorta was significantly higher in Group A than in Group B (p < 0.001). When ASIR-V weights were ≥60%, significant differences were found in the background noise, SNRAorta, and CNRSpinal cord between the two groups (all p < 0.05). In Group A, compared with FBP, the subjective score gradually increased as ASIR-V increased to 80%, which decreased when ASIR-V exceeded 80%. The visualization scores of the AKA (≥60%) and the ability to detect vessel continuity (≥80%) gradually increased as the ASIR-V weights increased (p < 0.05). The effective radiation dose was reduced by about 40.36% in Group A compared to Group B. CONCLUSIONS compared with conventional scanning protocol, using a combination of low tube voltage (100 kV) and 80% ASIR-V protocol could not only increase the visualization of the AKA, but also improve image quality and reduce the radiation doses.

Abstract
BACKGROUND Coarctation of the aorta (CoA) is a common congenital cardiovascular malformation, and improvements in the diagnostic process for surgical decision-making are important. We sought to compare the diagnostic accuracy of transthoracic echocardiography (TTE) with computed tomographic angiography (CTA) to diagnose CoA. METHODS We retrospectively reviewed 197 cases of CoA diagnosed by TTE and CTA and confirmed at surgery from July 2009 to August 2019. RESULTS The surgical findings confirmed that 19 patients (9.6%) had isolated CoA and 178 (90.4%) had CoA combined with other congenital cardiovascular malformations. The diagnostic accuracy of CoA by CTA was significantly higher than that of TTE (χ2 = 6.52, p = 0.01). In contrast, the diagnostic accuracy of TTE for associated cardiovascular malformations of CoA was significantly higher than that of CTA (χ2 = 15.36, p < 0.0001). Infants and young children had more preductal type of CoA, and PDA was the most frequent cardiovascular lesion associated with CoA. The pressure gradient was significantly decreased after the first operation, similar at 6 months, 1 year, and 3 years follow-ups by TTE. CONCLUSIONS CTA is more accurate as a clinical tool for diagnosing CoA; however, TTE with color Doppler can better identify associated congenital cardiovascular malformations. Therefore, combining TTE and CTA would benefit clinical evaluation and management in patients suspected of CoA. TTE was valuable for post-operation follow-up and clinical management.

Abstract
Double aortic arch (DAA) is a rare, congenital anomaly in small animals, resulting in a complete vascular ring encircling the esophagus and trachea, and subsequent compression of these organs. Few studies have reported utilizing CT angiography (CTA) for diagnosing DAA in dogs; thus, the imaging features are currently lacking in the literature. The objectives of this retrospective, multicenter, descriptive case series were to report the clinical and CTA characteristics of DAA in surgically treated cases. Medical records and CTA images were reviewed. Six juvenile dogs met the inclusion criteria (median age: 4.2 months; range: 2-5 months). The most common clinical signs included chronic regurgitation (100%), decreased body condition (67%), and coughing (50%). Common CTA features of DAA included a dominant left aortic arch (median diameter: 8.1 mm) and minor right aortic arch (median diameter: 4.3 mm; 83%), an aberrant right subclavian artery arising directly from the right aortic arch (83%), segmental esophageal constriction (100%), and variable degrees of dilation cranial to the heart base, and marked tracheal luminal compression (median percent change: -55%; 100%) and leftward curvature of the trachea at the level of the bifurcation of the aortic arches (100%). All dogs underwent successful surgical correction with only minor postoperative complications. Due to the similarity of clinical and imaging characteristics described to that of other forms of vascular ring anomalies (VRA), CTA is vital for the specific diagnosis of DAA in dogs.

Abstract
Background Although coronary computed tomography angiography (CCTA) is currently utilized as the frontline test to accurately diagnose coronary artery disease (CAD) in clinical practice, there are still debates regarding its use as a screening tool for the asymptomatic population. Using deep learning (DL), we sought to develop a prediction model for significant coronary artery stenosis on CCTA and identify the individuals who would benefit from undergoing CCTA among apparently healthy asymptomatic adults. Methods We retrospectively reviewed 11,180 individuals who underwent CCTA as part of routine health check-ups between 2012 and 2019. The main outcome was the presence of coronary artery stenosis of ≥70% on CCTA. We developed a prediction model using machine learning (ML), including DL. Its performance was compared with pretest probabilities, including the pooled cohort equation (PCE), CAD consortium, and updated Diamond-Forrester (UDF) scores. Results In the cohort of 11,180 apparently healthy asymptomatic individuals (mean age 56.1 years; men 69.8%), 516 (4.6%) presented with significant coronary artery stenosis on CCTA. Among the ML methods employed, a neural network with multi-task learning (19 selected features), one of the DL methods, was selected due to its superior performance, with an area under the curve (AUC) of 0.782 and a high diagnostic accuracy of 71.6%. Our DL-based model demonstrated a better prediction than the PCE (AUC, 0.719), CAD consortium score (AUC, 0.696), and UDF score (AUC, 0.705). Age, sex, HbA1c, and HDL cholesterol were highly ranked features. Personal education and monthly income levels were also included as important features of the model. Conclusion We successfully developed the neural network with multi-task learning for the detection of CCTA-derived stenosis of ≥70% in asymptomatic populations. Our findings suggest that this model may provide more precise indications for the use of CCTA as a screening tool to identify individuals at a higher risk, even in asymptomatic populations, in clinical practice.

Abstract
BACKGROUND Neonates with ductal-dependent pulmonary blood flow (DD-PBF) are at risk for pulmonary artery (PA) stenosis. The objective of this study was to identify preoperative cardiovascular computed tomography angiography (CTA) measures that are associated with the need for branch PA intervention. METHODS We identified neonates with DD-PBF who underwent preoperative CTA at our center and were followed for 24 months. The primary outcome was requiring intervention for branch PA stenosis at the initial or subsequent procedure. Patients were divided into three groups: 1) No PA intervention, 2) Initial PA intervention, and 3) Remote PA intervention. Measurements of the branch PAs and patent ductus arteriosus (PDA) were made prospectively. RESULTS Forty patients were included, 7 (18%) did not receive a PA intervention, 23 (58%) were in the initial PA intervention group, and 10 (25%) were in the remote PA intervention group. The distance from PA bifurcation to the largest diameter of the PA that receives the PDA showed a difference between the no-intervention group versus the initial and remote intervention groups (0.8 mm [IQR 0.7, 2.0], 8.2 mm [IQR 1.9, 13.7], 8.5 mm [IQR 6.5, 11.1], respectively, P = .02). The receiver operating characteristic curve showed a distance >2.2 mm had a sensitivity = 91% and specificity = 86% in predicting the need for PA intervention. CONCLUSION The distance from the PA bifurcation to the largest diameter of the branch PA that accepts the PDA on preoperative CTA is highly predictive of the need for initial or remote PA intervention in this group. Preoperative CTA should be considered for risk stratification in neonates undergoing intervention for DD-PBF.

Abstract
Background Coronary artery fistulas (CAFs), also, known as coronary arteriovenous malformation, are aberrant connections between coronary arteries and other structures, such as other artery branches or heart chambers. CAFs are infrequent and asymptomatic in young patients, but symptoms and complications become more frequent with age. CAFs can affect hemodynamic parameters and lead to complications, such as myocardial ischemia, heart failure, arrhythmia, and infective endocarditis. Objective The aim of this article was to present a typical CAF case with severe symptoms who underwent successful embolization to resolve their symptoms. Case presentation A 50-year-old Vietnamese male visited our cardiac outpatient clinic (S.I.S General Hospital, Can Tho, Vietnam) because of exertional dyspnea and chest pain. Signs of congestive heart failure and abnormal murmur were not presented on chest auscultation. Diagnostic digital subtraction angiography was performed to determine the detailed angioarchitecture of the CAF, revealing a fistulous connection between the left anterior descending artery (LAD) and the LV chamber through an aneurysm. In addition, the RCA measured 7 mm in diameter with a fistula (16 × 9 mm) draining into an aneurysm and then terminating into the LV chamber. The patient had an RCA aneurysm with a fistula into the LV. It was treated successfully by closing the fistula with a vascular plug. Access to the fistula was complex and difficult because of complications due to the CAF. After the procedure, the patient had no chest pain or shortness of breath and was discharged after three days. After six months, he was taking dual antiplatelet therapy and antihypertensive medications and felt better. We performed contrast computed tomography (CT) to examine the fistula after a year, which showed the successful closure of the fistula without any relevant alteration in the coronary artery. Conclusion CAF closure is indicated if patients have symptoms or secondary complications, and percutaneous closure is a safe and effective method to manage CAF. A CAF is rare and does not have specific symptoms, making it difficult to diagnose. Most patients are asymptomatic and have serious recent complications. Currently, the percutaneous transcatheter method is popular because it is noninvasive and successful in most patients.

Abstract
To investigate the normal diameter of the abdominal aorta and common iliac arteries of the middle-aged and elderly people in China and the relationship of the diameters with age, sex, height, weight, body mass index (BMI), and body surface area (BSA). This retrospective study enrolled 625 patients including 380 males and 245 females aged 60.00 years (interquartile range 13.00 years). All clinical data and the diameters of the abdominal aorta and common iliac arteries were analyzed. The diameter of the abdominal aorta was 21.49 ± 2.49 mm at the proximal, 16.94 (interquartile range 2.39) mm at the middle, and 15.65 (interquartile range 2.90) mm at the distal segment. The diameter of the common iliac artery was 10.76 (interquartile range 1.99) mm at the right proximal, 10.41 (interquartile range 2.05) mm at the left proximal, 10.74 (interquartile range 2.25) mm at the right distal, and 10.67 (interquartile range 2.22) mm at the left distal segment. The height, weight, BSA, BMI, diameters of the proximal, middle and distal abdominal aorta as well as the proximal and distal left and right common iliac arteries were significantly higher in males than those in females (P < .001). Height, weight, BSA, and BMI were significantly (P < .001) positively correlated with the diameter of the abdominal aorta and common iliac artery at the proximal, middle, and distal segments. The middle and distal diameters of the abdominal aorta were significantly higher in males than those in females (P < .05). The diameter of the abdominal aorta at the proximal, middle, and distal segment as well as the diameter of the left and right common iliac artery at the distal segment were significantly (P < .05) increased with age. The normal values of the diameter of the abdominal aorta and common iliac arteries are suggested for the middle-aged and elderly Chinese people for clinical reference. The diameters are gender related and significantly positively correlated with BSA, height, weight, and BMI, which is beneficial for the diagnosis and treatment planning of relevant vascular diseases.

Abstract
BACKGROUND We report a hitherto unreported combination of pulmonary stenosis, single coronary artery anomaly and coronary sinus to left atrial communication. Our case highlights the important value of coronary computed tomographic angiography and transthoracic echocardiography for the diagnosis of such anomalies and guidance for proper management. METHODS AND RESULTS A 64-year-old male presented chest tightness and shortness of breath for 2 days. Transthoracic echocardiography revealed a thickened pulmonary valve leaflet and subvalvular outflow tract stenosis, colour flow Doppler showed a significant accelerated blood flow in the pulmonary artery cavity originating from the subvalvular outflow tract, continuous wave Doppler revealed the transpulmonary valvular pressure gradient of 63mmHg. Computed tomographic angiography image reveals thickened pulmonary valve leaflets and subvalvular outflow tract stenosis, single coronary artery anomaly and levoatriocardinal vein. The patient underwent percutaneous pulmonary valve balloon dilatation, the post-procedural course was uneventful. DISCUSSION Pulmonary stenosis can occur as part of more congenital cardiac malformations or as rare primary isolated pulmonary stenosis, which includes the valvular, sub-valvular, or supra-valvular pulmonary stenosis. Single coronary artery anomalies are very rare, anomalous right coronary artery originates from proximal to mid-left anterior descending coronary artery is one such single coronary artery anomaly, in most cases, it is asymptomatic, diagnosed incidentally, and a benign entity has a better prognosis except if the right coronary artery is passing between the aorta and pulmonary artery. This course of the right coronary artery anomaly is malignant. Coronary sinus to left atrial communication includes a direct or indirect communication. The direct communication is described as a partial or complete absence of the roof between the coronary sinus and left atrium, as it is well known as the unroofed coronary sinus syndrome. The indirect communication is an anomalous bridging vein communicating the coronary sinus to the left atrium, which can be distinguished from classical unroofed coronary sinus syndrome. The venous collateral channel communication between the coronary sinus to the left atrium by a bridging vein is also categorized as a variant type of unroofed coronary sinus syndrome. Understanding coronary venous variations has significant clinical implications particularly in the realm of electrophysiology. The anatomical variations can have important consequences for procedures such as biventricular pacing and trans-coronary vein ablations. CONCLUSION Pulmonary stenosis combined with single coronary artery anomaly and bridging vein communication between the coronary sinus and the left atrium is an extremely rare.

Abstract
OBJECTIVES The anterolateral thigh (ALT) flap is a versatile workhorse flap for the reconstruction of head and neck defects; however, variations in the location of perforators are a significant concern. This prospective study proposes a rapid, effective, and convenient method for mapping the location of sizeable perforators on the curved thigh skin surface using the visual coordinate system in computed tomographic angiography (CTA) images. METHODS Fourteen patients suffering from defects after head and neck carcinoma resection underwent CTA prior to ALT flap reconstruction at the Department of Otolaryngology-Head and Neck Surgery, Beijing Friendship Hospital, Capital Medical University, from January 2018 to August 2021. Using sterile gauze swab developing lines pasted on the patients' thighs, we established a coordinate system visualized both in CTA images and the thighs. The perforator information was then compared between the CTA and intraoperative findings. RESULTS Twenty-one perforators were detected on CTA in the designed flaps, which were also confirmed during the operation with a visual pulse. The course and source of the perforators were consistent with the intraoperative findings. The distances of perforator coordinate points between CTA and intraoperative findings were <5 mm. Another five perforators (mostly without visual pulse) found intraoperatively could not be identified on preoperative CTA. Most flaps survived in their entirety, and one flap suffered a small area of necrosis due to perforator compression. CONCLUSION This study demonstrated the efficacy of a novel perforator mapping method for anterolateral thigh flaps.

Abstract
PURPOSE Changes in the flared end of balloon-expandable covered stent (BECS) may precede BECS-associated complications but are not regularly assessed with computed tomographic angiography (CTA) after fenestrated endovascular aneurysm repair (FEVAR). Validation of the flare geometric analysis (FGA) and assessment of intraobserver and interobserver variability are investigated in this study. METHODS Two series of 3 BeGraft BECSs (Bentley InnoMed GmbH, Hechingen, Germany) and 1 series of 3 Advanta V12 BECSs (Getinge AB, Göteborg, Sweden) were deployed in 3 side branches (45°, 60°, and 90° aortic branch angles) of an aorta phantom model. A standard post-FEVAR CTA scan was acquired. Computed tomographic angiography-derived measurements consisted of centerline reconstructions and placement of 3-dimensional coordinate markers by 2 observers in a vascular workstation. Flare geometric analysis calculates 3 BECS parameters: the circumferential flare-to-fenestration distance (FFD), which is the distance from the proximal end of the flare to fenestration, and diameters at the proximal end of the flare (Dflare) and at the fenestration (Dfenestration). Computed tomographic angiography-derived measurements were validated against microscopy measurements. Bland-Altman plots were used to determine the intraobserver and interobserver variability of the BECS parameters and intraclass correlation coefficient (ICC). RESULTS For each BECS, the FFD at 4 equidistant quadrants of the circumference, Dflare, and Dfenestration were calculated. The mean difference and repeatability coefficient (RC) of the validation were 0.8 (2.1) mm for FFD, 0.4 (1.0) mm for Dflare, and -0.2 (1.2) mm for Dfenestration. The mean intraobserver and interobserver difference (RC) was 0.5 (1.6) mm and 0.7 (2.6) mm for FFD, 0.1 (0.6) mm and 0.1 (0.7) mm for Dflare, and -0.1 (0.8) mm and -0.8 (1.0) mm for Dfenestration. The mean ICC of intraobserver variability was 0.86 for FFD, 0.94 for Dflare, and 0.78 for Dfenestration. The mean ICC of interobserver variability was 0.77 for FFD, 0.92 for Dflare, and 0.48 for Dfenestration. CONCLUSION This study showed that FGA of the flared ends of BECS can be performed with high accuracy in a phantom model, with good intraobserver and interobserver variability. Flare geometric analysis can be used to determine flare geometry of the BECS on standard post-FEVAR CTA scans.

Abstract
Aims: In this retrospective, multi-center study, we aimed to estimate the diagnostic accuracy and generalizability of an established deep learning (DL)-based fully automated algorithm in detecting coronary stenosis on coronary computed tomography angiography (CCTA). Methods and results: A total of 527 patients (33.0% female, mean age: 62.2 ± 10.2 years) with suspected coronary artery disease (CAD) who underwent CCTA and invasive coronary angiography (ICA) were enrolled from 27 hospitals from January 2016 to August 2019. Using ICA as a standard reference, the diagnostic accuracy of the DL algorithm in the detection of ≥50% stenosis was compared to that of expert readers. In the vessel-based evaluation, the DL algorithm had a higher sensitivity (65.7%) and negative predictive value (NPV) (78.8%) and a significantly higher area under the curve (AUC) (0.83, p < 0.001). In the patient-based evaluation, the DL algorithm achieved a higher sensitivity (90.0%), NPV (52.2%) and AUC (0.81). Generalizability analysis of the DL algorithm was conducted by comparing its diagnostic performance in subgroups stratified by sex, age, geographic area and CT scanner type. The AUCs of the DL algorithm in the aforementioned subgroups ranged from 0.79 to 0.86 and from 0.75 to 0.93 in the vessel-based and patient-based evaluations, both without significant group differences (p > 0.05). The DL algorithm significantly reduced post-processing time (160 [IQR:139–192] seconds), in comparison to manual work (p < 0.001). Conclusions: The DL algorithm performed no inferior to expert readers in CAD diagnosis on CCTA and had good generalizability and time efficiency.

Abstract
Background: Thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (TBAD) induces false lumen (FL) thrombosis, promotes favorable aortic remodeling, and makes an impact on abdominal aortic branch perfusion patterns. However, little is known about the long-term fate of aortic remodeling and abdominal aortic branch perfusion after TEVAR for TBAD and the effect of FL thrombosis status on these changes. Materials and methods: Between January 2014 and May 2021, 59 enrolled patients with acute TBAD were treated with TEVAR and had post-operative or follow-up images. Pre-operative, post-operative, and latest follow-up CT angiography (CTA) data were analyzed for the largest diameter of true lumen (TL), FL, and transaorta and for the FL thrombosis status on the stented thoracic aorta, unstented thoracic aorta, and abdominal aorta. Abdominal aorta perfusion patterns were characterized. Results: The mean follow-up period was 17.1 months. In the stented thoracic aorta, average TL diameters increased, average FL diameters decreased, and average transaortic diameters did not change; 82.6% of the patients had either a stable or shrinking transaortic size and 87% of the patients achieved total FL thrombosis. In the unstented thoracic aorta, average TL diameters increased, transaortic growth and no changes occurred in 39.1 and 45.7% of the patients, respectively, and complete FL thrombosis was present in 50% of the patients. In the abdominal aorta, average FL and transaortic diameters increased, aorta was expanded in 52.2% of the patients, and FL remained patent in 65.2% of the patients. Of the 354 branches, 37 branches (10.5%) exhibited changes in perfusion patterns, 22 branches (6.2%) demonstrated an increased TL perfusion, and 15 branches (4.2%) had an increased FL contribution. Compared with patent or partially thrombosed FL, complete FL thrombosis was accompanied by a bigger decrease in FL diameters, a larger increase in TL diameters, and a higher percentage of abdominal branch TL perfusion. Conclusions: In majority of the patients, TEVAR stabilized the size of the stented thoracic aorta, namely TL expansion and FL obliteration. However, abdominal aortic FL remained patent FL, and it was expanded with the resultant transaortic growth over a long follow-up period. Abdominal aortic branch perfusion patterns remained largely stable after TEVAR. The failure to achieve FL thrombosis negatively affects the remodeling of a contagious abdominal aortic dissection.

Abstract
OBJECTIVES The purpose of this study was to develop a risk prediction model for patients with nonobstructive CAD. BACKGROUND Among stable chest pain patients, most cardiovascular (CV) events occur in those with nonobstructive coronary artery disease (CAD). Thus, developing tailored risk prediction approaches in this group of patients, including CV risk factors and CAD characteristics, is needed. METHODS In PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) computed tomographic angiography patients, a core laboratory assessed prevalence of CAD (nonobstructive 1% to 49% left main or 1% to 69% stenosis any coronary artery), degree of stenosis (minimal: 1% to 29%; mild: 30% to 49%; or moderate: 50% to 69%), high-risk plaque (HRP) features (positive remodeling, low-attenuation plaque, and napkin-ring sign), segment involvement score (SIS), and coronary artery calcium (CAC). The primary end point was an adjudicated composite of unstable angina pectoris, nonfatal myocardial infarction, and death. Cox regression analysis determined independent predictors in nonobstructive CAD. RESULTS Of 2,890 patients (age 61.7 years, 46% women) with any CAD, 90.4% (n = 2,614) had nonobstructive CAD (mean age 61.6 yrs, 46% women, atherosclerotic cardiovascular disease [ASCVD] risk 16.2%). Composite events were independently predicted by ASCVD risk (hazard ratio [HR]: 1.03; p = 0.001), degree of stenosis (30% to 69%; HR: 1.91; p = 0.011), and presence of ≥2 HRP features (HR: 2.40; p = 0.008). Addition of ≥2 HRP features to: 1) ASCVD and CAC; 2) ASCVD and SIS; or 3) ASCVD and degree of stenosis resulted in a statistically significant improvement in model fit (p = 0.0036; p = 0.0176; and p = 0.0318; respectively). Patients with ASCVD ≥7.5%, any HRP, and mild/moderate stenosis had significantly higher event rates than those who did not meet those criteria (3.0% vs. 6.2%; p = 0.007). CONCLUSIONS Advanced coronary plaque features have incremental value over total plaque burden for the discrimination of clinical events in low-risk stable chest pain patients with nonobstructive CAD. This may be a first step to improve prevention in this cohort with the highest absolute risk for CV events.

Abstract
BACKGROUND There is no consensus on the method of obtaining abdominal aortic aneurysm (AAA) maximum diameters based on computed tomographic angiography, and the reproducibility and accuracy of different methods have recently been debated due to advancements in imaging. This study compared the two most common methods based on orthogonal planes and centerline of flow to determine the discordances and accuracy amongst experiences readers. METHODS The computed tomographic angiography max diameters of 148 AAAs were measured by three experienced observers, including a vascular surgeon, a radiologist and an imaging cardiologist. Observers used two different methods with standardized protocols: multiplanar reformations based on orthogonal planes, and a software using 3D aortic reconstructions to create centerline flow lumen providing diameters based on cross sections perpendicular to this lumen. Agreements and reliability of measurement methods were assessed by intra-class correlation coefficient and Bland - Altman analysis. Discordances between measurements of the methods and the original reported measurement, as well as outside hospitals were compared. RESULTS The average age of the cohort was 75 years and aortic diameters ranged from 3.8 to 9.6 cm. For orthogonal readings, there were agreements within 3 mm between 86% and 92% of the time, while centerline - reading agreement was between 88% and 94%, which was not statistically significant. The intra-class correlation coefficient was high between method type and between readers. Within methods, agreement was between 0.96 and 0.97, while within - reader agreement measures was between 0.96 and 0.98. In comparison to the original and the outside hospital reports, 10% ≥ of the original and 20% ≥ of the outside hospital reported measurements were discordant between the readers. CONCLUSION Maximal AAA measurements can have substantial variability leading to clinical significance and change in patient management and outcomes. Based on the results, orthogonal and centerline measurement methods have equally high agreements and concordance within 3 mm and low variations at a high volume center. However, when compared to the official read reports, there is high discordance rates that can significantly alter patient outcomes. A standardized method of measurement maximum diameter can reduce variations and discordances among different methods.

Abstract
Computed tomographic coronary angiography (CTCA) has prognostic value for early major adverse cardiac events (MACEs) after liver transplantation. However, the association between CTCA and long-term MACEs in liver transplant (LT) recipients remains unknown. We evaluated the association between CTCA and long-term MACEs within 5 years after living donor liver transplantation (LDLT). A total of 628 LDLT recipients who underwent CTCA were analyzed between 2010 and 2012. MACEs were investigated within 5 years after LDLT. The factors associated with long-term MACEs in transplant recipients were evaluated. Only 48 (7.6%) patients developed MACEs. In the Fine and Gray competing risk regression, a coronary artery calcium score (CACS) of >400 combined with obstructive coronary artery disease (CAD) (subdistribution hazard ratio: 5.01, 95% confidence interval: 2.37–10.58, p < 0.001), age (1.05, 1.01–1.10, p = 0.018), diabetes mellitus (2.43, 1.37–4.29, p = 0.002), dyslipidemia (2.45, 1.23–4.70, p = 0.023), and creatinine (1.19, 1.08–1.30, p < 0.001) were independently associated with long-term MACEs. CACS (>400) combined with obstructive CAD may be associated with MACEs within 5 years after LDLT, suggesting the importance of preoperative noninvasive CTCA in LT recipients. The evaluation of coronary artery stenosis on CTCA combined with CACS may have a prognostic value for long-term MACEs in LT recipients.

Introduction Vascular calcification is a recognized indicator of cardiovascular morbidity and mortality. Calcium scoring is a widely used tool to measure coronary artery calcification, however has limitations for use elsewhere in the body. There is currently no gold standard for quantifying abdominal aortic calcification (AAC). We propose a simple and reproducible method to assess the severity of AAC using multiplanar reconstruction (MPR) in CT angiograms (CTA). Methods A retrospective analysis of CTAs from 75 patients over two years was performed. Using a novel six-point scoring system, three radiologists independently scored the severity of AAC in the distal abdominal aorta. Interclass correlation (ICC) was used to assess the degree of agreement between the three raters. Calcium scoring of the same region was also calculated for each patient. We used Spearman's rank correlation coefficient to compare the CT calcium score with the corresponding average rater's atheroma score. Results There was significant agreement between raters’ scores, with an ICC value = 0.972, 95% (CI 0.959-0.981, p < 0.0001). There was also a strong correlation between an average rater's atheroma score with the corresponding CT calcium score, rho = 0.85 (p < 0.0001). Conclusion The results show excellent reproducibility of scores between radiologists, as well as a strong correlation between this novel scoring tool and calcium scores, indicating that it is a reliable method for the grading of AAC. We propose that this simple semi-quantitative method could form a widely used system for AAC disease stratification.

Abstract
Background We examined sex differences in nonstenotic carotid plaque composition in patients with embolic stroke of undetermined source (ESUS). Methods and Results Patients with anterior circulation ischemic stroke imaged with neck computed tomographic angiography who met criteria for ESUS or had atrial fibrillation were identified. Patients with atrial fibrillation were included as a negative control. Semiautomated plaque quantification software analyzed carotid artery bifurcations. Plaque subcomponent (calcium, intraplaque hemorrhage [IPH], and lipid rich necrotic core) volumes were compared by sex and in paired analyses of plaque ipsilateral versus contralateral to stroke. Multivariate linear regressions tested for associations. Ninety‐four patients with ESUS (55% women) and 95 patients with atrial fibrillation (47% women) were identified. Men with ESUS showed significantly higher volumes of calcified plaque (63.9 versus 19.6 mm3, P<0.001), IPH (9.4 versus 3.3 mm3, P=0.008) and a IPH/lipid rich necrotic core ratio (0.17 versus 0.07, P=0.03) in carotid plaque ipsilateral to stroke side than women. The atrial fibrillation cohort showed no significant sex differences in plaque volumes ipsilateral to stroke. Multivariate analyses of the ESUS cohort showed male sex was associated with IPHipsi (β=0.49; 95% CI, 0.11–0.87) and calciumipsi (β=0.78; 95% CI, 0.33–1.23). Paired plaque analyses in men with ESUS showed significantly higher calcified plaque (63.9 versus 34.1 mm3, P=0.03) and a trend of higher IPHipsi (9.4 versus 7.5 mm3, P=0.73) and lipid rich necrotic coreipsi (59.0 versus 48.4 mm3, P=0.94) volumes. Conclusions Sex differences in carotid plaque composition in ESUS suggest the possibility of a differential contribution of nonstenosing carotid plaque as a stroke mechanism in men versus women.

Abstract
Objective We investigated whether thoraco-cervical CTA provided useful information to determine an access route (AR) for mechanical thrombectomy (MT). Methods We included acute stroke patients who (1) were admitted between January 2018 and December 2018 and (2) underwent MT for large artery occlusion in the anterior circulation and were able to be treated within 24 hours of the time last known to be well. We evaluated the AR, occlusion site, aortic arch (AA) type, take-off angles (TOA) between the arch and the left common carotid artery (CCA) or the brachiocephalic artery (BCA), successful insertion rate (SIR) of the guiding catheter, puncture-to-initial angiography time (PtIA), and puncture-to-reperfusion time (PtR). Results We analyzed 32 patients: femoral-artery access (group F) in 26 and brachial-artery access (group B) in 6 patients. There were no differences in arch types between the two groups, but there were differences in occlusion sites: proximal CCA occlusion in two patients in the B group. Moreover, the TOA of the CCA was less than 25° in two patients in the B group. In the F and B groups, the SIR was 100%, the median PtIA was 9.0 and 9.6 minutes, and the median PtR was 54 and 72 minutes, respectively. Conclusion Thoraco-cervical CTA provided useful information to determine the appropriate AR for MT. SIR of 100% and short PtIA were achieved.

Abstract
Objective: To evaluate the clinical value of early post-operative computed tomographic angiography (CTA) after direct extracranial-intracranial (EC-IC) bypass surgery in moyamoya patients. Methods: A retrospective analysis of all adult moyamoya patients treated at our center from 2013 to 2019 with a direct EC-IC bypass was performed. Early post-operative CTA (within 24 h after surgery) was compared with conventional digital subtraction angiography (DSA) 6-12 months after surgery. If available, magnetic resonance time-of-flight angiography (MR-TOF) was evaluated 3 months and 6-12 months post-operatively as well. Imaging results were analyzed and compared with CTA, MR-TOF and DSA, whereat DSA was used as the final and definite modality to decide on bypass patency. Results: A total of 103 direct EC-IC bypasses in 63 moyamoya patients were analyzed. All inclusion criteria were met in 32 patients (53 direct bypasses). In 84.9% the bypass appeared definitively, in 5.7% uncertainly and in 9.4% not patent according to early post-operative CTA. MR-TOF suggested definitive bypass patency in 86.8% 3 months after surgery and in 93.5% 6-12 months after surgery. DSA 6-12 months post-operatively showed a patency in 98.1% of all bypasses. The positive predictive value (to correctly detect an occluded bypass) on post-operative CTA was 12.5%, the negative predictive value (to correctly detect a patent bypass) was 100% with a sensitivity of 100% and a specificity of 86.5%. Conclusion: Early post-operative CTA has a high predictive value to confirm the patency of a bypass. On the other hand, a high false positive rate of (according to CTA) occluded bypasses after direct EC-IC bypass surgery can be seen. This must be considered critically when initiating possible therapeutic measures.

Abstract
BACKGROUND LVADs provide life-sustaining treatment for patients with heart failure, but their complexity allows for complications. One complication, LVAD outflow graft obstruction, may be misdiagnosed as intraluminal thrombus, when more often it is extraluminal compression from biodebris accumulation. It can often be treated endovascularly with stenting. This case series describes diagnostic and procedural techniques for the treatment of left ventricular assist device (LVAD) outflow graft obstruction. METHODS We present four patients with LVADs who developed LVAD outflow graft obstruction within the bend relief-covered segment. All were initially diagnosed with computed tomographic angiography (CTA). All underwent invasive evaluation with intravascular ultrasound (IVUS), then were treated with stenting. After misdiagnosing a twist, we developed the technique of balloon "graftoplasty" to ensure suitability for stent delivery in subsequent cases. RESULTS All patients presented with low-flow alarms and symptoms of low output, and were diagnosed with outflow graft obstruction by CTA. In all four, IVUS confirmed an extraluminal etiology. Patient 1 was treated with stenting and had a good outcome. Patient 2's obstruction was from twisting, rather than biodebris accumulation, and had sub-optimal stent expansion and ultimately required surgery. Balloon "graftoplasty" was used in subsequent cases to ensure subsequent stent expansion. Patients 3 and 4 were successfully stented. All improved after treatment. CONCLUSIONS In patients with LVAD outflow graft obstruction, IVUS can distinguish intraluminal thrombus from extraluminal compression. Balloon "graftoplasty" can ensure that the outflow graft will respond to stenting. Many cases of LVAD outflow graft obstruction should be amenable to endovascular treatment.

Abstract
Inflammation is a pivotal driver of atherosclerotic plaque progression and rupture and is a target for identifying vulnerable plaques. However, challenges arise with the current in vivo imaging modalities for differentiating vulnerable atherosclerotic plaques from stable plaques due to their low specificity and sensitivity. Herein, we aimed to develop a novel multimodal imaging platform that specifically targets and identifies high-risk plaques in vivo by detecting active myeloperoxidase (MPO), a potential inflammatory marker of vulnerable atherosclerotic plaque. Methods: A novel multimodal imaging agent, 5-HT-Fe3O4-Cy7 nanoparticles (5HFeC NPs), used for active MPO targeting, was designed by conjugating superparamagnetic iron oxide nanoparticles (SPIONs) with 5-hydroxytryptamine and cyanine 7 N-hydroxysuccinimide ester. The specificity and sensitivity of 5HFeC NPs were evaluated using magnetic particle imaging (MPI), fluorescence imaging (FLI), and computed tomographic angiography (CTA) in an ApoE-/- atherosclerosis mouse model. Treatment with 4-ABAH, an MPO inhibitor, was used to assess the monitoring ability of 5HFeC NPs. Results: 5HFeC NPs can sensitively differentiate and accurately localize vulnerable atherosclerotic plaques in ApoE-/- mice via MPI/FLI/CTA. High MPI and FLI signals were observed in atherosclerotic plaques within the abdominal aorta, which were histologically confirmed by multiple high-risk features of macrophage infiltration, neovascularization, and microcalcification. Inhibition of active MPO reduced accumulation of 5HFeC NPs in the abdominal aorta. Accumulation of 5HFeC NPs in plaques enabled quantitative evaluation of the severity of inflammation and monitoring of MPO activity. Conclusions: This multimodal MPI approach revealed that active MPO-targeted nanoparticles might serve as a method for detecting vulnerable atherosclerotic plaques and monitoring MPO activity.

Abstract
BACKGROUND AND PURPOSE: When the femoral approach for mechanical thrombectomy (MT) in acute ischemic stroke (AIS) is limited, trans-brachial or-radial access is an alternative. However, transbrachial insertion of a 9Fr (outer diameter [OD]) balloon guide catheter (BGC) into the carotid artery is not feasible. Computed tomographic (CT) angiography (CTA) may provide vascular anatomical information for successful insertion. We investigated CTA anatomical features for successful transbrachial insertion of a 9Fr BGC into the carotid artery. MATERIALS AND METHODS: We analyzed AIS patients who underwent CTA and transbrachial MT using a 9Fr BGC between 2014 and 2016. We evaluated the successful insertion rate and CT angiographic anatomical features. RESULTS: Twenty-four patients met our inclusion criteria. We achieved successful insertion in 18 (75%) of 24 cases: 7 (58.3%) of 12 for left carotid arteries and 11 (91.7%) of 12 for right carotid arteries. Successful insertion was achieved in 4 of 4 bovine aortic arch for left carotid occlusion and in 3 of 8 nonbovine aortic arches for left carotid occlusion. We achieved successful insertion in 3 nonbovine cases with takeoff angles ≥23° and failed insertion in 5 cases with takeoff angles <23°. We achieved successful insertion in 10 of the 10 cases with takeoff angles ≥25° in the right common carotid artery. The BGC was broken in 1 of 2 cases with takeoff angles <25°. CONCLUSIONS: The CTA provided a high likelihood of successful 9Fr OD BGC insertion without an introducer sheath. Successful transbrachial insertion was achieved in bovine left carotid cases, in nonbovine left carotid cases with takeoff angles ≥23°, and in right carotid cases with takeoff angles ≥25°.

Abstract
Background The objective was to validate the hypothesis and evaluate whether the presence or absence of accessory renal artery can be predicted on the basis of volumetric parameters of kidney and diameter of the main renal artery (mRA). Methods This retrospective analysis was performed in a total of 60 kidneys in 30 patients, who had computed tomographic (CT) angiography. The kidneys were segregated into control and study groups depending on the absence or presence of accessory renal artery. The total renal volumes were measured using renal length, breadth, and height in mm3. The renal artery diameters were also measured in mm, in the postostial segment. Renal volume/renal artery diameter (V/d) was measured for each kidney in two groups, and the difference in mean V/d values (in mm2) in two groups was measured for statistical significance. Results The mean V/d value in the study group with presence of the accessory renal artery was found to be 23,444.7 mm2 (range: 16,229.1-32,490.0). The V/d value in the control group with the absence of accessory renal artery was found to be 19,717.15 mm2 (range: 13,704.6-28,000.0). The mean values in the two groups showed a statistically significant difference in the V/d with a P value of 0.001 (P < 0.05). Conclusion The study suggests that the possibility of the presence of the accessory renal artery is directly proportional to the total renal volume and inversely proportional to the diameter of mRA. The use of integrated volumetric parameter (V/d) is therefore likely to play a key role in the prediction of the presence of accessory renal artery on imaging studies. Renal volumetry on CT angiography may help predict the presence of accessory renal artery and thus may have implications on renal Doppler studies.

Abstract
BACKGROUND Despite advances in non-invasive vascular imaging, detection of renal artery stenosis via catheter angiography is the criterion standard for the diagnosis of renovascular hypertension (RVH). However, because of lack of evidence, the utility of various blood tests and imaging modalities remains unclear. METHODS We retrospectively analyzed the utility of blood tests (plasma renin activity [PRA], aldosterone, and renal vein renin [RVR] values) and imaging studies (computed tomography angiography [CTA], kidney ultrasonography [US]) by comparing them with catheter angiography. Ten pediatric patients with RVH at two institutions from January 2008 to December 2017 were recruited. The sensitivities for diagnosing RVH via imaging and blood tests (kidney [US], PRA, and aldosterone) were derived by examining patient records. Furthermore, the sensitivity and specificity of CT angiography were calculated by considering both the affected and non-affected renal arteries of the patients. RESULTS A high sensitivity for diagnosing RVH via kidney US (89%) and PRA (80%) was observed. The sensitivity and specificity of CTA were 100%, each. RVR sampling did not aid in the diagnosis of RVH; only two of six patients with unilateral RVH showed significant laterality of RVR boundary ratios. Renal scintigraphy facilitated detection of a non-functional kidney (split renal function <5%). CONCLUSIONS RVH in children could be diagnosed utilizing non-invasive blood and imaging tests, without catheter angiography. We recommend kidney length measurement along with measurement of PRA level, as a simple and highly useful screening test, followed by CTA as a diagnostic test.

Abstract
OBJECTIVE The purpose of this study was to evaluate the feasibility of posterior occipital condyle screw (OCS) placement analysis of the safe trajectory area for screw insertion. METHODS Computed tomographic angiography scans of patients (46 males and 27 females) with normal occipitocervical structures were obtained consecutively. Vertebral artery (VA)-occiput distance <4.0 mm was defined as "unfeasible" for OCS fixation, and occipital-atlas angulation was measured to assess the feasibility of screw placement. Next, the placement of 3.5 mm diameter OCS was simulated, the probability of breach of structures surrounding occipital condyles was calculated, and placement parameters were analyzed. RESULTS OCS placement was feasible in 91.1% (133/146) of occipital condyles, and the feasible probability also presented a significant sex-related difference: The probability was higher for males than for females (95.7% vs. 83.3%, p < 0.05). The incidence of anatomical structures injured under screw placement limitation was 18.8% (VA), 81.2% (hypoglossal canal), 59.4% (occipital-atlas joint), and 40.6% (occiput bone surface). There were no significant differences between the left and right condyles in relation to the measured parameters (p > 0.05). The screw range of motion was significantly smaller in females than in males (p < 0.05). The feasibility of OCS placement and OCS range of motion were significantly greater in the kyphosis group (>5°) than in the other two groups (p < 0.05). CONCLUSION OCS placement is a feasible technique for occipital-cervical fusion. The male group and occipitocervical region kyphosis group had a wider available space for OCS placement. Tangent angulation may be useful for the accurate and safe placement of an OCS.

Abstract
Background Transthoracic echocardiography (TTE) plays a vital role in the assessment of the surgical management of patients with tetralogy of Fallot (TOF). Accurate assessment of the main pulmonary valve annulus, main pulmonary artery (MPA), and branch pulmonary arteries are crucial for decision-making regarding the surgical approach in the form of total correction. It is also important for performing a systemic-to-pulmonary artery shunt operation and affects the outcome. In some patients with poor echogenic windows, it is sometimes difficult to obtain accurate measurements. Cardiac computed tomographic angiography (CTA) can be a superior diagnostic modality. Therefore, the aim of this study was to evaluate the degree of agreement between TTE and CTA in assessing the main pulmonary valve annulus and the size of the MPA and its branches among patients with TOF patients. Methodology Patients above one year of age, with TOF, presented during the study period of six months - from January 1, 2019, to June 30, 2019, were included in the study. All the patients had TTE and cardiac CTA to assess the annulus and the size of the MPA and its branches (right pulmonary artery (RPA) and left pulmonary artery (LPA)). CTA measurement of all parameters was compared with TTE measurement of the same on three different views each by computing the Bland-Altman plot and Pearson correlation coefficients. Results A total of 73 TOF patients were included in this study. The correlation coefficients between CTA and TTE for the measurement of the annulus were 0.767 and 0.833 for the parasternal short-axis view and the subcostal view, respectively. The correlation coefficients between CTA and TTE for the measurement of MPA were 0.820 and 0.866 for the parasternal short-axis view and the suprasternal view, respectively. The correlation coefficients between CTA and TTE for the measurement of RPA were 0.883 and 0.897 for the parasternal short-axis view and the suprasternal view, respectively. Similarly, the correlation coefficients between CTA and TTE for the measurement of LPA were 0.848 and 0.877 for the parasternal short-axis view and the suprasternal view, respectively. Conclusion In conclusion, there is a strong correlation and agreement between cardiac CTA and TTE for the assessment of the annulus and the size of the pulmonary artery (PA) and its branches in patients with TOF.

Abstract
Objective Pericardial adipose tissue volume (PATV) is related to the mechanism of coronary artery disease (CAD), but its association with CAD risk factors is not clear. This study aimed to investigate the relationships between PATV and its associated factors. Methods A total of 682 inpatients were consecutively enrolled in this study. Patients were divided into the high PATV group (PATV ≥174.5 cm3; n = 506) and low PATV group (PATV < 174.5 cm3; n = 176). Multiple linear regression analysis was conducted to evaluate the related factors of PATV. Multivariable logistic regression was used to analyze the risk factors of CAD. Results Left ventricular fat volume, right ventricular fat volume, body mass index, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were significant and independent risk factors of enlargement of PATV. Increased PATV was identified as an independent risk factor of CAD, and increased pulse pressure was also independently and positively correlated with CAD. Conclusions PATV is significantly correlated with the classic risk factors of CAD. Pulse pressure is also correlated with PATV. PATV is an independent risk factor of CAD, and pericardial adipose tissue may alternatively be used in non-invasive diagnostic examination of CAD.

Abstract
BACKGROUND Patients with non-ST-segment elevation myocardial infarction and elevated high-sensitivity cardiac troponin levels often routinely undergo invasive coronary angiography (ICA), but many do not have obstructive coronary artery disease. OBJECTIVES This study investigated whether cardiovascular magnetic resonance imaging (CMR) or computed tomographic angiography (CTA) may serve as a safe gatekeeper for ICA. METHODS This randomized controlled trial (NCT01559467) in 207 patients (age 64 years; 62% male patients) with acute chest pain, elevated high-sensitivity cardiac troponin T levels (>14 ng/l), and inconclusive electrocardiogram compared a CMR- or CTA-first strategy with a control strategy of routine clinical care. Follow-up ICA was recommended when initial CMR or CTA suggested myocardial ischemia, infarction, or obstructive coronary artery disease (≥70% stenosis). Primary efficacy and secondary safety endpoints were referral to ICA during hospitalization and 1-year outcomes (major adverse cardiac events and complications), respectively. RESULTS The CMR- and CTA-first strategies reduced ICA compared with routine clinical care (87% [p = 0.001], 66% [p < 0.001], and 100%, respectively), with similar outcome (hazard ratio: CMR vs. routine, 0.78 [95% confidence interval: 0.37 to 1.61]; CTA vs. routine, 0.66 [95% confidence interval: 0.31 to 1.42]; and CMR vs. CTA, 1.19 [95% confidence interval: 0.53 to 2.66]). Obstructive coronary artery disease after ICA was found in 61% of patients in the routine clinical care arm, in 69% in the CMR-first arm (p = 0.308 vs. routine), and in 85% in the CTA-first arm (p = 0.006 vs. routine). In the non-CMR and non-CTA arms, follow-up CMR and CTA were performed in 67% and 13% of patients and led to a new diagnosis in 33% and 3%, respectively (p < 0.001). CONCLUSIONS A novel strategy of implementing CMR or CTA first in the diagnostic process in non-ST-segment elevation myocardial infarction is a safe gatekeeper for ICA.

Abstract
Venous thromboembolism is a common disease which remains underdiagnosed because of nonspecific presentations which can range from asymptomatic incidental imaging findings to sudden death. Symptoms can overlap with comorbid cardiopulmonary disease, and risk factors that offer clues to the clinician are not always present. The diagnostic approach can vary depending on the specific clinical presentation, but ruling in the diagnosis nearly always depends on lung imaging. Overuse of diagnostic testing is another recognized problem; a cautious, evidence-based approach is required, although physician gestalt must be acknowledged. The following review offers an approach to the diagnosis of acute pulmonary embolism based on the assessment of symptoms, signs, risk factors, laboratory findings, and imaging studies.

Abstract
Background/aim Acute aortic dissection (AAD) is a rare but fatal disease if left untreated. Symptoms are often similar to common conditions; therefore, the diagnostic strategy is important. We aimed to identify the atypical symptoms in a timely manner without putting patients at greater risk for undetected AAD. Materials and methods We conducted a retrospective observational study of 59 AAD patients with both atypical and typical symptoms from January 2012 to December 2016. Patients with atypical symptoms continuing more than 30 min underwent a D-dimer test and computed tomography (CT) or computed tomographic angiography (CTA). Results Of the 59 AAD patients, 22 were atypical. In the atypical group, the median delay time in our hospital was 3.1 h; average delay time after July 2015 was shorter than average delay time before June 2015 (16.59 ± 24.70 vs. 1.90 ± 0.57 h, P = 0.076). Conclusions For patients in the emergency department who are suspected of having AAD, incorporating atypical symptoms with high levels of D-dimer into a triage strategy could improve the efficiency of clinical decision making. Furthermore, essential education directed towards the recognition of the atypical symptoms of AAD for front-line physicians may aid in a timely diagnosis, as compared with the usual assessments in the emergency department.

Abstract
Evaluation of the left atrium and left atrial appendage for the presence of thrombus prior to cardioversion and pulmonary vein isolation, and of the entire heart for embolic sources in the setting of cryptogenic stroke, has long been standard medical care. Guidelines have uniformly recommended transesophageal echocardiography (TEE) to accomplish these goals. In recent years, computed tomographic angiography has demonstrated diagnostic accuracy similar to that of TEE for the detection of thrombus. Analysis of the pertinent data and relative merits of the 2 technologies leads to the conclusions that: 1) both modalities have some unique, nonoverlapping capabilities that may dictate their use in specific situations; 2) computed tomographic angiography is a reasonable alternative to TEE when the primary aim is to exclude left atrial and left atrial appendage thrombus and in patients in whom the risks associated with TEE outweigh the benefits; and 3) both options should be discussed with the patient in the setting of shared decision making.

Abstract
BACKGROUND Renal fibromuscular dysplasia (FMD) is typically diagnosed in young hypertensive women. The 2014 European FMD Consensus recommended screening in all hypertensive women <30 yo. However, the prevalence of renal FMD in young/middle-aged hypertensive women remains unclear. The aim of this work was to assess the prevalence and characteristics of renal FMD in hypertensive women ≤50 yo. METHODS We retrospectively included all consecutive women aged ≤50 years referred to our Hypertension Unit from 2014 to 2017 and collected standardized information on patient characteristics and screening modalities. RESULTS Of 1083 incident hypertensive patients, 157 patients fitted with inclusion criteria. The prevalence of renal FMD varied between 3.2% in the whole sample and 7.5% in patients explored by CTA and/or MRA (n = 67). In the subgroup of patients ≤30 yo (n = 32), the corresponding figures were 3.1% and 5.6%. The yearly prevalence of FMD tended to increase over time, in parallel with increased use of CTA/MRA as a first-line imaging modality. Out of 5 patients with renal FMD, 2 were revascularized and 1 had extra-renal FMD. CONCLUSIONS The prevalence of renal FMD in young/middle-aged hypertensive women is probably one order of magnitude higher than previously assumed, in the range of 3%-8%, depending on imaging modalities. While the diagnosis of FMD does not influence short-term management in all patients, it may allow close monitoring and prevention of complications of the disease over time. This analysis provides the rationale for a prospective, multicentre study aiming at determining the cost-effectiveness of systematic screening for renal FMD.

Abstract
Aim: The purpose of the study is to evaluate the relationship between red blood cell distribution width (RDW) and coronary calcium score in diabetic patients. Methods: Hematological parameters of 100 diabetic (Type II) patients were assessed. Computed tomographic angiography was used to asses coronary artery calcium (CAC) score. Results: Mean age of the study cohort was 55 years (males: 60%). Mean RDW was 12.7%. Mean CAC score was 243. There was a significant correlation between RDW and each of: CAC scores (r = 0.53; p < 0.001) and severity of coronary artery disease (CAD; r = 0.25; p = 0.047). A cut-off value >14.2% (receiver operating characteristic curves) predicted CAC score >400. A cut-off value >-14.6% predicted the presence of significant CAD. Conclusion: Diabetic patients with high-CAC scores and significant CAD had higher RDW.

Abstract
Isolated sinus of Valsalva aneurysm is a rare congenital pathology associated with a life-threatening course when untreated. In this article, we report a 60-year-old male patient with an isolated aneurysm of right sinus of Valsalva treated by modified Bentall procedure. The patient with cardiac symptoms applied to our clinic for further evaluation. Enhanced computed tomographic angiography and transthoracic echocardiography revealed an isolated aneurysm of right sinus of Valsalva. An optimal management for the condition is not clear, while early surgical intervention is recommended due to potentially life-threatening complications.
