Abstract
BACKGROUND Although anomalous aortic origin of a coronary artery (AAOCA) is associated with risk of sudden cardiac arrest (SCA), there is a spectrum of disease, with the appropriate management for many remaining unclear. Increasing data warrant review for an updated perspective on management. METHODS A panel of congenital cardiac surgeons, cardiologists, and imaging practitioners reviewed the current literature related to AAOCA and its management. Survey of relevant publications from 2010 to the present in PubMed was performed. RESULTS The prevalence of AAOCA is 0.4% to 0.8%. Anomalous left coronary artery is 3 to 8 times less common than anomalous right coronary, but carries a much higher risk of SCA. Nevertheless, anomalous right coronary is not completely benign; 10% demonstrate ischemia, and it remains an important cause of SCA. Decision-making regarding which patients should be recommended for surgical intervention includes determining anatomic features associated with ischemia, evidence of ischemia on provocative testing, and concerning cardiovascular symptoms. Ischemia testing continues to prove challenging with low sensitivity and specificity, but the utility of new modalities is an active area of research. Surgical interventions focus on creating an unobstructed path for blood flow and choosing the appropriate surgical technique given the anatomy to accomplish this. Nontrivial morbidity has been reported with surgery, including new-onset ischemia. CONCLUSIONS A proportion of patients with AAOCA demonstrate features and ischemia that warrant surgical intervention. Continued work remains to improve the ability to detect inducible ischemia, to risk stratify these patients, and to provide guidance in terms of which patients warrant surgical intervention.

Abstract
OBJECTIVES Anomalous aortic origin of a coronary artery (AAOCA) is a group of rare congenital heart defects with various clinical presentations. The lifetime-risk of an individual living with AAOCA is unknown, and data from multicentre registries are urgently needed to adapt current recommendations and guide optimal patient management. The European AAOCA Registry (EURO-AAOCA) aims to assess differences with regard to AAOCA management between centres. METHODS EURO-AAOCA is a prospective, multicentre registry including 13 European centres. Herein, we evaluated differences in clinical presentations and management, treatment decisions and surgical outcomes across centres from January 2019 to June 2023. RESULTS A total of 262 AAOCA patients were included, with a median age of 33 years (12-53) with a bimodal distribution. One hundred thirty-nine (53.1%) were symptomatic, whereas chest pain (n = 74, 53.2%) was the most common complaint, followed by syncope (n = 21, 15.1%). Seven (5%) patients presented with a myocardial infarction, 2 (1.4%) with aborted sudden cardiac death. Right-AAOCA was most frequent (150, 57.5%), followed by left-AAOCA in 51 (19.5%), and circumflex AAOCA in 20 (7.7%). There were significant differences regarding diagnostics between age groups and across centres. Seventy-four (28.2%) patients underwent surgery with no operative deaths; minor postoperative complications occurred in 10 (3.8%) cases. CONCLUSIONS Currently, no uniform agreement exists among European centres with regard to diagnostic protocols and clinical management for AAOCA variants. Although surgery is a safe procedure in AAOCA, future longitudinal outcome data will hopefully shed light on how to best decide towards optimal selection of patients undergoing revascularization versus conservative treatment.

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
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
INTRODUCTION There are many uncertainties surrounding anomalous aortic origin of a coronary artery (AAOCA) including the pathophysiology of sudden cardiac death, how to best risk stratify patients, how to best evaluate patients, who would benefit from exercise restriction, who should undergo surgical intervention, and which operation to perform. AREAS COVERED The goal of this review is to provide a comprehensive but succinct overview of AAOCA to help clinicians with the difficult task of navigating optimal evaluation and treatment of an individual patient with AAOCA. EXPERT OPINION Beginning in year 2012, some of our authors proposed an integrated, multi-disciplinary working group which has become the standard management strategy for patients diagnosed with AAOCA. A multi-disciplinary team with a focus on shared decision-making with the patients/families is likely necessary to optimize outcomes. Long-term follow-up and research are needed to improve our understanding of AAOCA.

Abstract
OBJECTIVE Management of anomalous aortic origin of coronary arteries has been variable, and limited data are available on early and late outcomes. METHODS We report a single institution's experience with a protocolized approach to 148 consecutive patients who underwent surgical unroofing of intramural anomalous aortic origin of coronary arteries (June 2003 to December 2020). The management algorithm included preoperative and postoperative cross-sectional and echocardiographic imaging, exercise testing, and a standardized operative technique. RESULTS The median age of the cohort was 44.4 years (range, 4 months to 83 years); 130 patients had an anomalous right coronary artery, and 19 patients had an anomalous left coronary artery. Surgical unroofing was an isolated procedure in 118 patients (80%) and a concomitant procedure in 30 patients (20.3%). There were 2 (1%) early deaths; both were reoperations for aortic root or valve replacement. Over a median follow-up of 9.5 (interquartile range, 5-12.3) years, there were 5 late deaths, 3 due to noncardiac causes and 2 due to unknown cause. Late survival after anomalous aortic origin of coronary arteries repair at 10 and 15 years was 94.5% and 94.5%, respectively. There were no early or late deaths in the pediatric cohort with a median follow-up of 10.9 years (interquartile range, 6.9-12.1). At a median clinical follow-up of 3.9 years (interquartile range, 1.1-9.5), 36 patients had chest pain but none with evidence of ischemia related to the unroofing. CONCLUSIONS Surgical unroofing of anomalous aortic origin of coronary arteries can be performed safely with low early mortality, even in the setting of concomitant procedures. Late survival is excellent, with the vast majority being symptom free.

Abstract
The aortic anomaly of the right coronary artery (AAORCA) originating from the left aortic sinus (LCS) is a rare malformation that may result in sudden cardiac death (SCD), which may be due to the dilated aorta-pulmonary artery affecting the blood supply of the coronary artery. However, there are still some disputes about the treatment of the AAORCA. Herein, we present a rare case of AAORCA from the LCS with aortic dissection (AD). Considering the risk of dissection rupture and SCD, an emergency surgery of aortic replacement and coronary anomaly correction was performed successfully for the patient. This report illustrated that AAORCA complicated with acute AD (AAD) is lethal and may promote the occurrence of coronary ischemia or sudden death by a new “double-kill” mechanism that myocardial ischemia was based on the extent of a fixed and a dynamic component like slit-like ostium, proximal narrowing, acute take-off angle and intramural course with the elliptic vessel shape. There is no doubt that surgery is the best treatment option for the AAORCA with AAD.

Abstract
Objectives This study sought to characterize coronary artery disease (CAD) among adults diagnosed with an anomalous aortic origin of a coronary artery (AAOCA). We hypothesized that coronaries with anomalous origins have more severe CAD stenosis than coronaries with normal origins. Methods This single-center study of 763 adults with AAOCA consisted of 620 patients from our cardiac catheterization database (1958-2009) and 273 patients from electronic medical records query (2010-2021). Within left main, anterior descending, circumflex, and right coronary arteries, the CAD stenosis severity, assessed by invasive or computer tomography angiography, was modeled with coronary-level variables (presence of an anomalous origin) and patient-level variables (age, sex, comorbidities, and which of the four coronaries was anomalous). Results Of the 763 patients, 472 (60%) had obstructive CAD, of whom, 142/472 (30%) had obstructive CAD only in the anomalous coronary. Multivariable modeling showed similar CAD stenosis severity between coronaries with anomalous versus normal origins (P = .8). Compared with AAOCA of other coronaries, the anomalous circumflex was diagnosed at older ages (59.7 ± 11.1 vs 54.3 ± 15.8 years, P < .0001) and was associated with increased stenosis in all coronaries (odds ratio, 2.7; 95% confidence interval, 2.2-3.4, P < .0001). Conclusions Among adults diagnosed with AAOCA, the anomalous origin did not appear to increase the severity of CAD within the anomalous coronary. In contrast to the circumflex, AAOCA of the other vessels may contribute a greater ischemic burden when they present symptomatically at younger ages with less CAD. Future research should investigate the interaction between AAOCA, CAD, and ischemic risk to guide interventions.

However, the specific anatomic indications for surgery are unclear, so dobutamine-stress instantaneous wave-free ratio (iFR) is increasingly used. Meanwhile, advances in fluid–structure interaction (FSI) modeling can simulate the pulsatile hemodynamics and tissue deformation. We sought to evaluate the feasibility of simulating the resting and dobutamine-stress iFR in AAORCA using patient-specific FSI models and to visualize the mechanism of ischemia within the intramural geometry and associated lumen narrowing. Methods We developed 6 patient-specific FSI models of AAORCA using SimVascular software. Three-dimensional geometries were segmented from coronary computed tomography angiography. Vascular outlets were coupled to lumped-parameter networks that included dynamic compression of the coronary microvasculature and were tuned to each patient's vitals and cardiac output. Results All cases were interarterial, and 5 of 6 had an intramural course. Measured iFRs ranged from 0.95 to 0.98 at rest and 0.80 to 0.95 under dobutamine stress. After we tuned the distal coronary resistances to achieve a stress flow rate triple that at rest, the simulations adequately matched the measured iFRs (r = 0.85, root-mean-square error = 0.04). The intramural lumen remained narrowed with simulated stress and resulted in lower iFRs without needing external compression from the pulmonary root. Conclusions Patient-specific FSI modeling of AAORCA is a promising, noninvasive method to assess the iFR reduction caused by intramural geometries and inform surgical intervention. However, the models’ sensitivity to distal coronary resistance suggests that quantitative stress-perfusion imaging may augment virtual and invasive iFR studies.

Abstract
BACKGROUND Un-roofing is the most common technique utilized for repair of anomalous aortic origin of a coronary artery (AAOCA). There are very few publications directly comparing un-roofing to another surgical technique, like reimplantation. METHODS The prospectively collected Children's Memorial Hermann Heart Institute Society of Thoracic Surgeon's Database was retrospectively reviewed from 2007 to 2021. Surgical patients were included if they underwent un-roofing or reimplantation of the AAOCA. The primary outcomes of this study were operative characteristics and postoperative outcomes. Secondary outcomes included angiographic outcomes, aortic regurgitation incidence, ventricular function, and symptom relief. RESULTS From 2007 to 2021, there were 12 patients who underwent either a reimplantation (n = 9, 73%) or un-roofing (n = 3, 27%) for an AAOCA. The hospital length of stay was a median of 1.8 days longer for reimplantation compared to un-roofing. The last follow-up echocardiogram was a median of 52.2 days later in the reimplantation group. There was one patient (11%) in the reimplantation group that had more than or equal to mild aortic regurgitation and mild systolic ventricular dysfunction. Outpatient follow-up was incomplete and there was no postoperative computed tomographic angiography in the un-roofing cohort. CONCLUSIONS Coronary artery reimplantation is a valuable alternative surgical technique to un-roofing for the repair of AAOCA. There are still some concerns with the creation of aortic regurgitation or incomplete symptom relief with any surgical technique. Longer-term follow-up and prospective studies will be needed to show an effective reduction of myocardial ischemia and risk of sudden cardiac death.
