Abstract
INTRODUCTION Anomalous origin of the right coronary artery from the left sinus of Valsalva (R-ACAOS) is a relatively rare condition that can potentially lead to devastating outcomes. The current study aims to investigate the cardiac-related disorders among patients with incidental R-ACAOS diagnosis through computed tomography angiography (CTA). METHODS The current cross-sectional study has been conducted on 50 patients diagnosed with R-ACAOS who underwent CTA. Based on CTA, the patients' were categorized as R-ACAOS with interarterial course and non-interarterial course. The demographic and medical characteristics, any history of cardiac intervention and New York Heart Association (NYHA) Functional Classification at the time of diagnosis were recruited. Patients were revisited to assess cardiac-associated variables, including symptoms, the presence of heart failure and current NYHA function class. RESULTS The variables including the history of cardiac intervention (P-value<0.001), the presence of heart failure (P-value = 0.010) and NYHA function class at the time of diagnosis (P-value = 0.006) were remarkably higher among those with interarterial course of R-ACAOS; while, the other variables including chest pain at rest (P-value = 0.55) or on exertion (P-value = 0.12), current NYHA function class, current cardiac-associated symptoms except for dyspnea at rest (P-value = 0.012), mortality and coronary calium score did not differ (P-value>0.05). coronary interventions led to significantly improved NYHA function class (P-value<0.05). CONCLUSION Based on the findings of the current study, R-ACAOS with interarterial course leads to significantly higher rates of atherosclerotic-related symptoms and events compared with the other types of RCA anomalies. Moreover, coronary interventions led to significantly improved NYHA functional class regardless of R-ACAOS category.

Abstract
BACKGROUND The management of adult patients with anomalous aortic origin of the right coronary artery (ARCA) from the left aortic sinus poses important challenges. The presence of symptoms or documented ischaemia, the anatomical characteristics of the ostium, and the course of the coronary determine decision-making. METHODS A retrospective review was performed of all cases of surgical management of ARCA at a single centre. The primary endpoints were mortality and myocardial infarction at 30 days. Secondary endpoints included recurrence of symptoms, freedom from re-intervention, and mortality during long-term follow-up. RESULTS From October 2019 to August 2023, 15 adult patients underwent surgery for ARCA; 13 patients were included in this study (mean age 53.9±11.1 years; 10 female). A slit-like orifice, a long intramural segment, and an interarterial course were found in all patients. Twelve (12) patients (92.3%) were symptomatic: nine with angina, combined with dyspnoea on exertion in seven. One (1) patient had history of pre-syncope. One (1) patient presented with out-of-hospital cardiac arrest. All patients underwent formal unroofing of the orifice and intramural portion of the ARCA; five patients had a concomitant procedure. No 30-day mortality nor myocardial infarction was recorded. At a mean follow-up of 20.1±12.8 months, all patients were alive. One (1) patient (7.6%) developed recurrent dyspnoea; investigations showed no ischaemia. No repeated interventions were required. CONCLUSIONS Surgical unroofing of anomalous coronary artery in the adult is safe and effective; correction of both the slit-like orifice and intramural portion of the anomaly provides a durable result in patients with ARCA.

Abstract
Coronary artery anomalies (CAAs) comprise a wide spectrum of anatomic entities, with diverse clinical phenotypes. We present a case of an anomalous right coronary artery arising from the left aortic sinus with an interarterial course, a potentially fatal condition that can precipitate ischemia and sudden cardiac death. CAAs are increasingly detected in adults, mostly as incidental findings in the course of cardiac evaluation. This is due to the expanding use of invasive and noninvasive cardiac imaging, usually in the work-up for possible CAD. The prognostic implications of CAAs in this group of patients remain unclear. In AAOCA patients, appropriate work-up with anatomical and functional imaging should be performed for risk stratification. An individualized approach to management should be adopted, considering symptoms, age, sporting activities and the presence of high-risk anatomical features and physiologic consequences (such as ischemia, myocardial fibrosis, or cardiac arrhythmias) detected on multimodality imaging or other functional cardiac investigations. This comprehensive and up to date review seeks to crystallize current data in the recent literature, and proposes a clinical management algorithm for the clinician faced with the conundrum of managing such conditions.

Abstract
As widely discussed in recent literature, coronary artery anomalies only occasionally lead to potentially serious myocardial ischemic events. The most important group of coronary anomalies has been called anomalous coronary artery origin from an abnormal sinus or a site in the ascending aorta (ACAOS). Only some cases of right- or left-sided intramural-course ACAOS (R-ACAOS-IM or L-ACAOS-IM) can potentially cause significant symptoms or sudden cardiac death, typically during exertion in athletes. After an ACAOS-IM case is qualitatively identified, it is necessary to establish the severity of associated stenosis (which is always present to some degree in ACAOS-IM). The 3 stages of a comprehensive diagnostic process are: 1. initial screening of high-risk populations (young elite athletes, optimally by use of magnetic resonance imaging [MRI]) to identify the prevalence of similar cases in large populations (the denominator of any risk calculation); 2. evaluating symptoms (chest pain, syncope, or sudden death) and performing stress testing; 3. in patients found to carry ACAOS-IM, evaluating the severity of coronary obstruction by intravascular ultrasonography, which is an objective, definitive, and quantifying imaging modality for this condition, essential in selected carriers of such anomalies. The possible treatment alternatives are discussed and updated.

Abstract
PURPOSE OF REVIEW Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital coronary anomaly with the potential to cause myocardial ischemia and adverse cardiac events. The presence of AAOCA anatomy itself does not necessarily implicate a need for revascularization. Therefore, the purpose of this review is to assess how noninvasive comprehensive anatomic- and physiologic evaluation may guide patient management. RECENT FINDINGS The assessment of AAOCA includes an accurate description of the anomalous origin/vessel course including anatomical high-risk features such as a slit-like ostium, proximal narrowing, elliptic vessel shape, acute take-off angle, intramural course, and possible concomitant coronary atherosclerosis and hemodynamics. Various cardiac imaging modalities offer unique advantages and capabilities in visualizing these anatomical and functional aspects of AAOCA. This review explored the role of noninvasive multimodality imaging in the characterization of AAOCA by highlighting the strengths, limitations, and potential applications of the current different cardiac imaging methods, with a focus on the pathophysiology of myocardial ischemia and stress testing protocols.

Abstract
An anomalous origin of the right coronary artery from the opposite sinus of Valsalva with an intramural course (R-ACAOS-IM) may cause sudden cardiac death in children and adolescents. However, the natural history and management of patients in whom this anomaly is detected later during adulthood remains uncertain. The goals of this study were to assess the impact of an R-ACAOS-IM on the clinical outcomes in an adult population and to determine if adult patients with this anomaly who do not have significant coronary artery disease (CAD) can be managed safely without surgical intervention. A database review identified patients aged >35 years with anomalous coronary arteries diagnosed by cardiac catheterization or coronary computed tomography angiography. The outcomes of patients with R-ACAOS-IM were compared with patients with anomalous left circumflex coronary arteries with retroaortic course (LCx-RA) (an anomaly not associated with ischemic events). The primary outcome was all-cause mortality. The study population consisted of 185 patients aged 59 ± 12 years. Clinical characteristics were similar in the R-ACAOS-IM (n = 88) and LCx-RA (n = 97) groups. At a follow-up of 6.6 ± 4.5 years, there was no difference in mortality (hazard ratio 0.64, 95% confidence interval 0.32 to 1.28, p = 0.20) when adjusted for gender, age, and CAD. A subgroup analysis of 88 patients with no obstructive CAD managed nonoperatively found no difference between the LCx and R-ACAOS-IM groups in mortality (hazard ratio 2.45, 95% confidence interval 0.45 to 13.40, p = 0.30). There was no significant difference between the 2 groups in the composite outcome of death, nonfatal myocardial infarction, or survived cardiac arrest. The outcome of adult patients who have anomalous R-ACAOS-IM are similar to patients who have anomalous LCx-RA with a known benign course. In conclusion, these results suggest that most patients who survive this anomaly into adulthood may be managed conservatively without intervention.

Abstract
Anomalous aortic origin of a coronary artery (AAOCA) is a rare congenital heart condition with fixed and dynamic stenotic elements, potentially causing ischemia. Invasive coronary angiography under stress is the established method for assessing hemodynamics in AAOCA, yet it is costly, technically intricate, and uncomfortable. Computational fluid dynamics (CFD) simulations offer a noninvasive alternative for patient-specific hemodynamic analysis in AAOCA. This systematic review examines the role of CFD simulations in AAOCA, encompassing patient-specific modeling, noninvasive imaging-based boundary conditions, and flow characteristics. Screening articles using AAOCA and CFD-related terms prior to February 2023 yielded 19 publications, covering 370 patients. Over the past four years, 12 (63%) publications (259 patients) employed dedicated CFD models, whereas 7 (37%) publications (111 patients) used general-purpose CFD models. Dedicated CFD models were validated for fixed stenosis but lacked dynamic component representation. General-purpose CFD models exhibited variability and limitations, with fluid-solid interaction models showing promise. Interest in CFD modeling of AAOCA has surged recently, mainly utilizing dedicated models. However, these models inadequately replicate hemodynamics, necessitating novel CFD approaches to accurately simulate pathophysiological changes in AAOCA under stress conditions.

Abstract
OBJECTIVES Iodixanol contrast media with different doses using computed tomography angiography (CTA) and perfusion (CTP) to diagnose coronary artery disease (CAD) in overweight patients lacks assessment. Our study compared iodixanol 320 mg I/ml and 270 mg I/ml on image quality and accuracy of CTA combined CTP (CTA-CTP) to diagnose CAD. METHODS Overweight patients with suspected of CAD were randomized into iodixanol 270 group (received iodixanol 270 mg I/ml) and iodixanol 320 group (received iodixanol 320 mg I/ml). Based on these characteristics data, receiver operating characteristic (ROC) curve and corresponding area under the curve (AUC) were plotted to assess the sensitivity and specificity of the two administrations. RESULTS The subjective definition score, signal to noise ratio, and CT value of aorta in iodixanol 320 group were higher than iodixanol 270 group. In iodixanol 270 group: the image exhibited a normal state of both vessels and myocardial perfusion; and the AUC, specificity, and sensitivity were 0.376, 66.67, and 80.46, respectively. In iodixanol 320 group: the image exhibited a diameter stenosis in right coronary artery and myocardial infarction of inferior wall and proximal inferior wall septum, as well as myocardial perfusion defects; and the AUC, specificity, and sensitivity in iodixanol 320 group were 0.824, 75.00, and 89.87, respectively. CONCLUSION Accuracy and image quality of iodixanol 320 mg I/ml in the diagnosis of CAD with CTA-CTP was higher than using iodixanol 270 mg I/ml.

Abstract
Invasive fractional flow reserve (FFR) measured by a pressure wire is a reference standard for evaluating functional stenosis in coronary artery disease. Coronary computed tomography angiography-derived fractional flow reserve (CT-FFR) uses advanced computational analysis methods to noninvasively obtain FFR results from a single conventional coronary computed tomography angiography data to evaluate the hemodynamic significance of coronary artery disease. More and more evidence has found good correlation between the results of noninvasive CT-FFR and invasive FFR. CT-FFR has proven its potential in optimizing patient management, improving risk stratification and prognosis, and reducing total health care costs. However, there is still a lack of standardized interpretation of CT-FFR technology in real-world clinical settings. This expert consensus introduces the principle, workflow, and interpretation of CT-FFR; summarizes the state-of-the-art application of CT-FFR; and provides suggestions and recommendations for the application of CT-FFR with the aim of promoting the standardized application of CT-FFR in clinical practice.

A comprehensive analysis of the intramural segment in interarterial anomalous coronary arteries using computed tomography angiography. EUROPEAN HEART JOURNAL OPEN 2022; 2:oeac031. [PMID: 35919578 PMCID: PMC9277063 DOI: 10.1093/ehjopen/oeac031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 04/08/2022] [Accepted: 04/25/2022] [Indexed: 11/12/2022]
Abstract
Abstract
Aims
An anomalous coronary artery originating from the opposite sinus of Valsalva (ACAOS) with an interarterial course can be assessed using computed tomography angiography (CTA) for the presence of high-risk characteristics associated with sudden cardiac death. These features include a slit-like ostium, acute angle take-off, proximal luminal narrowing, and an intramural segment. To date, no robust CTA criteria exist to determine the presence of an intramural segment. We aimed to deduct new CTA parameters to distinguish an intramural course of interarterial ACAOS.
Methods and results
Twenty-five patients with an interarterial ACAOS (64% female, mean age 46 years, 88% right ACAOS) from two academic hospitals were evaluated. Inclusion criteria were the availability of a preoperative CTA scan (0.51 mm slice thickness) and peroperative confirmation of the intramural segment. Using multiplanar reconstruction of the CTA, the distance between the lumen of the aorta and the lumen of the ACAOS [defined as ‘interluminal space’ (ILS)] was assessed at 2 mm intervals along the intramural segment. Analysis showed a mean ILS of 0.69 ± 0.15 mm at 2 mm from the ostium. At the end of the intramural segment where the ACAOS becomes non-intramural, the mean ILS was significantly larger (1.27 ± 0.29 mm, P < 0.001). Interobserver agreement evaluation showed good reproducibility (intraclass correlation coefficient 0.77, P < 0.001). Receiver operator characteristic analysis demonstrated that at a cut-off ILS of <0.95 mm, an intramural segment can be diagnosed with 100% sensitivity and 84% specificity.
Conclusion
The ILS is introduced as a novel and robust CTA parameter to identify an intramural course of interarterial ACAOS. An ILS of <0.95 mm is indicative of an intramural segment.

Abstract
Abstract
In recent years, the role of pre-participation evaluation (PPE) in the prevention of sudden cardiac death in competitive athletes has become evident. Most physicians routinely supplement assessment by resting electrocardiogram with imaging techniques, such as echocardiography. The primary goal of imaging in the clinical assessment of competitive athletes is to exclude cardiovascular conditions associated with adverse outcomes. Cardiac computed tomography is emerging as an important technique for stratifying cardiovascular risk and assessing coronary artery disease (CAD), particularly in master athletes. Conversely, in young athletes, this technique has the best non-invasive coronary artery resolution and provides valuable details on coronary artery anatomy. Recent technical developments have brought about a dramatic reduction in radiation exposure, a major drawback of this diagnostic method; nowadays cardiac computed tomography may be performed at a dose of barely one millisievert. The present review provides a practical guide for the use of cardiac computed tomography in the PPE of competitive athletes, with a specific focus on its value for detecting congenital coronary anomalies and CAD in young and master athletes, respectively.

Evaluation of the Ostium in Anomalous Origin of the Right Coronary Artery with an Interarterial Course Using Dynamic Cardiac CT and Implications of Ostial Findings. Korean J Radiol 2022; 23:172-179. [PMID: 35029074 PMCID: PMC8814709 DOI: 10.3348/kjr.2021.0270] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 10/14/2021] [Accepted: 10/19/2021] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVE We aimed to evaluate the ostium of right coronary artery of anomalous origin from the left coronary sinus (AORL) with an interarterial course throughout the cardiac cycle on CT and analyze the clinical significance of the ostial findings. MATERIALS AND METHODS From January 2011 to December 2015, 68 patients (41 male, 57.3 ± 12.1 years) with AORL with an interarterial course and retrospective cardiac CT data were included. AORL was classified as high or low ostial location based on the pulmonary annulus in the diastolic and systolic phases on cardiac CT. In addition, the height, width, height/width ratio, area, and angle of the ostium were measured in both cardiac phases. After cardiac CT, patients were followed until December 31, 2020 for major adverse cardiac events (MACE). Clinical and CT characteristics associated with MACE were explored using Cox regression analysis. RESULTS During a median follow-up period of 2071 days (interquartile range, 1180.5-2747.3 days), 13 patients experienced MACE (19.1%, 13/68). Seven (10.3%, 7/68) had the ostial location change from high in the diastolic phase to low in the systolic phase. In the univariable analysis, younger age (hazard ratio [HR] = 0.918, p < 0.001), high ostial location (HR = 4.008, p = 0.036), larger height/width ratio (HR = 5.621, p = 0.049), and smaller ostial angle (HR = 0.846, p = 0.048) in the systolic phase were significant predictors of MACE. In multivariable cox regression analysis, younger age (adjusted HR = 0.917, p = 0.002) and high ostial location in the systolic phase (adjusted HR = 4.345, p = 0.026) were independent predictors of MACE. CONCLUSION The ostial location of AORL with an interarterial course can change during the cardiac cycle, and high ostial location in the systolic phase was an independent predictor of MACE.

Abstract
Anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva is a rare but clinically relevant congenital anomaly, since the RCA may be subjected to cyclical compression due to its interarterial course. At least in the past, most patients experienced bad outcomes before being diagnosed with a malignant variant. Chronic (often subclinical) myocardial ischemia and possible arrhythmias are common complications. Once symptoms or electrocardiographic signs of myocardial ischemia become apparent, a quick diagnosis is mandatory. We report the case of a late symptomatic woman in whom RCA originated from the opposite sinus of Valsalva. The malignant variant was confirmed at transesophageal echocardiography directly in the catheterization laboratory, soon after angiographic diagnosis of aberrant origin.

Abstract
Coronary artery anomalies (CAA) represent a heterogeneous group of congenital disorders of the arterial coronary circulation, defined by an anomalous origin of the coronary ostium and/or vessel course. Of particular interest are anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS). The interarterial variants (with the anomalous vessel situated between the great arteries) are historically called "malignant," based on an anticipated higher risk for myocardial ischemia and sudden cardiac death (SCD), especially affecting young patients during strenuous physical activity. However, the interarterial course itself may not be the predominant cause of ischemia, but rather represents a surrogate for other ischemia-associated anatomical high-risk features. As the exact pathophysiology of ACAOS is not well-understood, there is a lack of evidence-based guidelines addressing optimal diagnostic work-up, downstream testing, sports counseling, and therapeutic options in patients with ACAOS. Therefore, treating physicians are often left with uncertainty regarding the clinical management of affected patients. This review focuses on the pathophysiologic consequences of ACAOS on myocardial ischemia and discusses the concept of the interplay between fixed and dynamic coronary stenosis. Further, we discuss the advantages and limitations of the different diagnostic modalities and give an outlook by highlighting the gaps of knowledge in the assessment of such anomalies.
