Abstract
We describe what we believe to be the first reported case of a neonate with right coronary ostial atresia with the right coronary artery originating from the left circumflex coronary artery, in conjunction with a right coronary artery to right ventricle fistula in a patient with otherwise normal cardiac anatomy. This was found following an evaluation for a continuous murmur at 2 weeks of life with elevated troponin and abnormal electrocardiogram. Thus far the child has required no intervention and is asymptomatic at 17 months of age, but he will require long-term follow-up to monitor the size of the fistula and potential for myocardial insufficiency.

Clinical Outcomes in Adult Patients With an Anomalous Right Coronary Artery from the Left Sinus of Valsalva. Am J Cardiol 2023; 204:122-129. [PMID: 37541148 DOI: 10.1016/j.amjcard.2023.07.066] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 07/07/2023] [Accepted: 07/13/2023] [Indexed: 08/06/2023]
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
OBJECTIVE Anomalous aortic origin of the coronary artery is a rare congenital cardiac anomaly. The aim of this study was to present our experience with patients who underwent surgery for the anomalous aortic origin of the coronary artery. METHODS This was a retrospective review of our experience with patients who had anomalous aortic origin of the coronary artery from 2019 to 2022. RESULTS Seven patients were managed for anomalous aortic origin of the coronary artery, including five males and two females. The median age of the patients were 16 years (IQR, 14.5-26 years). Five patients had anomalous aortic origin of the right coronary artery and two patients had anomalous aortic origin of the left coronary artery. Five patients were treated surgically, one patient refused surgical treatment despite myocardial ischaemia symptoms, and the other one was not operated because she had no symptoms. Two patients underwent pulmonary root anterior translocation and left main coronary artery unroofing procedure, one patient underwent right coronary artery unroofing procedure, one patient underwent pulmonary artery lateral translocation procedure, and the last patient underwent right coronary artery osteal translocation procedure. The post-operative mortality or myocardial infarction was not observed in any patient. Patients were followed for a median of 10 months (IQR, 6.75-20.5 months) after repair. CONCLUSION The data suggest that surgical repair of anomalous aortic origin of the coronary artery can be performed confidently and can be very effective for relieving myocardial ischaemia symptoms. Different surgical techniques can be used in anomalous aortic origin of the coronary artery according to the course and origin of the coronary arteries. To the our knowledge, pulmonary root anterior translocation and coronary artery unroofing procedure were performed for the first time in the literature.

Abstract
OBJECTIVES: To evaluate the use of CABG utilising an isolated pedicled Right Internal Thoracic Artery (RITA) or Left Internal Thoracic Artery (LITA) or the Pure Internal Thoracic Artery (PITA) technique to treat anomalous aortic origin of coronary artery (AAOCA). METHODS: A retrospective review of all patients at our institution over an 8-year period (2013–2021) who underwent surgery for AAOCA was performed. Data assessed included patient demographics, initial presentation, morphology of coronary anomaly, surgical procedure, cross-clamp time, cardiopulmonary bypass time, and long-term outcome. RESULTS: A total of 14 patients underwent surgery, including 11 males (78.5%) with a median logistic EuroSCORE of 1.605 (IQR 1.34). The median age was 62.5 years (IQR 48.75). Presentation was angina (7 patients), acute coronary syndrome (5 patients), incidental findings in aortic valve pathology (2 patients). AAOCA morphology varied: RCA from left coronary sinus (6), RCA from left main stem (3), left coronary artery from the right coronary sinus (1), left main stem arising from right coronary sinus (2) and circumflex artery arising from the right coronary sinus (2). Overall, 7 patients had co-existing flow-limiting coronary artery disease. CABG was performed using either a pedicled skeletonized RITA, LITA or PITA technique. There was no perioperative mortality. Overall median follow-up time was 43 months. One patient presented with recurrent angina secondary to graft failure at 2 years and there were two non-cardiac-related deaths at 4 and 35 months. CONCLUSION: The use of internal thoracic artery grafts can provide a durable treatment option in patients with anomalous coronary arteries. The potential risk of graft failure in patients with no flow-limiting disease should be very carefully considered. However, a proposed benefit of this technique is the use of a pedicle flow to increase the long-term patency. More consistent results are obtained when ischaemia can be demonstrated preoperatively.

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
We report the case of a patient with anomalous right coronary artery (RCA) unmasked by acute perimyocarditis who continued to have ischemic symptoms despite total resolution of perimyocarditis and required surgical intervention of the anomalous RCA. This case was further complicated by ventricular arrhythmia after surgical repair. Collaboration among different cardiac specialists was essential in this case. (Level of Difficulty: Advanced.)

Abstract
Anomalous aortic origin of a coronary artery (AAOCA), especially the interarterial course of the right or left coronary artery, predisposes paediatric patients to myocardial ischaemia. This rare condition is a leading cause of sudden cardiac death. General paediatricians face challenges when diagnosing this anomaly, and they should pay particular attention to the recurrence of exercise-related syncope without prodromal symptoms, chest pain and dyspnoea. An accurate transthoracic echocardiogram with Doppler colour flow mapping is the best method to use to identify AAOCA. CONCLUSION: Identifying an AAOCA is challenging, and we provide advice on clinical red flags and diagnostic approaches for general paediatricians.

Abstract
Anomalous aortic origin of the coronary arteries (AAOCA) is a rare congenital abnormality. It is usually asymptomatic and often found incidentally during coronary angiography. However, it can also be discovered during the autopsy of young healthy adults who have suffered from sudden cardiac death (SCD). AAOCA represents the second most common cause of SCD in young athletes. Herein, we report a case of a 39-year-old patient with left-sided right coronary anomaly with multiple high-risk features who presented with life-threatening symptoms for SCD but normal electrocardiography, echocardiography, and cardiac markers. The coronary computed tomography revealed an anomalous coronary artery from the left sinus of Valsalva with a hypoplasic origin and a high-risk path between the aorta and the pulmonary artery with a short intramural path. He was surgically managed with a coronary artery bypass with an uneventful follow-up.

Abstract
PURPOSE OF REVIEW To review anomalous aortic origin of a coronary artery (AAOCA) anatomy, prevalence, mechanism and risk of ischemia, presentation, evaluation, management, and future directions. RECENT FINDINGS Although most anatomic variants of AAOCA are benign, a small number are associated with increased risk of sudden death. A complete evaluation, including the use of advanced noninvasive imaging and provocative testing should be performed on nearly every patient with AAOCA. On the basis of recent studies, the ischemic risk appears to be greatest with a left anomalous coronary artery but an anomalous right coronary artery is not benign. Other risk factors include: a left anomalous coronary with an intramural course, high take-off, or slit-like orifice, and a right anomalous coronary with a longer intramural course. Exercise restriction is rarely recommended. Management primarily consists of nonoperative care, or surgical repair in those who are symptomatic or who have high-risk variants. Surgery itself continues to evolve; however, it is not benign, with a higher than expected chance of morbidity. SUMMARY Advances have been made over the past decade regarding management of patients with AAOCA; however, the mechanism of ischemia and ability to predict risk is still incompletely understood. Management decisions should be based on anatomy, results of investigations, and shared decision-making with patients and their families. Surgery may be recommended for those at higher risk and should be done at centers experienced in AAOCA surgery. Future research should be collaborative in order to share experiences and insights to help advance our understanding of risk and ultimately to improve patient management.

Abstract
Background Most reported cases of right anomalous coronary artery from the opposite sinus (R-ACAOS) have benign clinical outcomes. However, patients with left ACAOS (L-ACAOS) and some of the patients with R-ACAOS are more at risk for arrhythmias and sudden cardiac death, which remains a major concern. Here we report the prevalence and anatomical features of ACAOS patients. Moreover, we explore the high-risk morphological signs and evaluate their mid-term prognostic value in R-ACAOS patients without surgical intervention. Methods Data from coronary computed tomography angiography (CTA) of 30,593 patients, pertaining to a single center over 5 consecutive years, were retrospectively analyzed. The image analysis included stenosis severity ranking and high-risk anatomy evaluation, based on the commercially available image post-processing software OsirX. Patients with R-ACAOS and without evidence of coronary atherosclerosis (CAD) were followed-up, with recording of the cardiovascular clinical events. Cox regression analysis was performed to identify the potential anatomical risk factors of cardiovascular clinical events for non-CAD R-ACAOS patients, using R project. Results The prevalence of ACAOS in the study population was 0.69% (211/30593). Significant differences were found between patients with mild (< 50%) and severe (> 50%) stenosis, in terms of height-to-weight ratio (HW ratio), take-off angle, and proximal stenosis length. A total of 54 cardiovascular clinical events were observed among 108 non-CAD R-ACAOS patients and an average follow-up of 27.8 ± 18.7 months. Among those patients’ anatomical features, stenosis severity was the main risk factor for cardiovascular clinical events during the mid-term follow-up, with a risk ratio of 4.14 (95% CI: 1.78 to 9.63, P < 0.001). Conclusions Among patients referred to coronary CTA, the overall incidence of ACAOS was 0.69%. For patients with R-ACAOS, severe stenosis was the independent risk factor of adverse clinical events in the mid-term follow-up, and positive clinical intervention might be needed to help them avoid the malignant clinical events.

Abstract
Endothelial nitric oxide synthase (eNOS) and oxidative stress are critical to embryonic coronary artery development. Maternal diabetes increases oxidative stress and reduces eNOS activity in the fetal heart. Sapropterin (Kuvan®) is an orally active, synthetic form of tetrahydrobiopterin (BH4) and a co-factor for eNOS with antioxidant properties. The aim of the present study was to examine the effects of sapropterin on fetal coronary artery development during pregestational diabetes in mice. Diabetes was induced by streptozotocin to adult female C57BL/6 mice. Sapropterin (10 mg/kg/day) was orally administered to pregnant mice from E0.5 to E18.5. Fetal hearts were collected at E18.5 for coronary artery morphological analysis. Sapropterin treatment to diabetic dams reduced the incidence of coronary artery malformation in offspring from 50.0% to 20.6%. Decreases in coronary artery luminal diameter, volume and abundance in fetal hearts from diabetic mothers, were prevented by sapropterin treatment. Maternal diabetes reduced epicardial epithelial-to-mesenchymal transition (EMT) and expression of transcription and growth factors critical to coronary artery development including hypoxia-inducible factor 1a (Hif1a), Snail1, Slug, β-catenin, retinaldehyde dehydrogenase 2 (Aldh1a2), basic fibroblast growth factor (bFGF) and vascular endothelial group factor receptor 2 (Vegfr2) in E12.5 hearts. Additionally, eNOS phosphorylation was lower while oxidative stress was higher in E12.5 hearts from maternal diabetes. Notably, these abnormalities were all restored to normal levels after sapropterin treatment. In conclusion, sapropterin treatment increases eNOS activity, lowers oxidative stress and reduces coronary artery malformation in offspring of pregestational diabetes. Sapropterin may have therapeutic potential in preventing coronary artery malformation in maternal diabetes.

Abstract
Anomalous origin of the right coronary artery (ARCA) is an extremely rare cardiac pathology. The coronary artery can potentially course between the aorta and the pulmonary artery, putting the patient at risk for sudden cardiac death. Even rarer is an ARCA that arises from the left main coronary artery (LMCA). To our knowledge, this is the first case where an ARCA arising entirely from the LMCA is associated with critical bicuspid aortic valve stenosis.

Abstract
OBJECTIVES Anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus of Valsalva is a rare cardiac anomaly associated with sudden cardiac death (SCD). Single-center studies describe surgical repair as safe, although medium- and long-term effects on symptoms and risk of SCD remain unknown. We sought to describe outcomes of surgical repair of AAOCA. METHODS We reviewed institutional records for patients who underwent AAOCA repair, from 2001 to 2016, at 2 affiliated institutions. Patients with associated heart disease were excluded. RESULTS In total, 60 patients underwent AAOCA repair. Half of the patients (n = 30) had an anomalous left coronary artery arising from the right sinus of Valsalva and half had an anomalous right. Median age at surgery was 15.4 years (interquartile range, 11.9-17.9 years; range, 4 months to 68 years). The most common presenting symptoms were chest pain (n = 38; 63%) and shortness of breath (n = 17; 28%); aborted SCD was the presenting symptom in 4 patients (7%). Follow-up data were available for 54 patients (90%) over a median of 1.6 years. Of 53 patients with symptoms at presentation, 34 (64%) had complete resolution postoperatively. Postoperative mild or greater aortic insufficiency was present in 8 patients (17%) and moderate supravalvar aortic stenosis in 1 (2%). One patient required aortic valve replacement for aortic insufficiency. Two patients required reoperation for coronary stenosis at 3 months and 6 years postoperatively. CONCLUSIONS Surgical repair of AAOCA is generally safe and adverse events are rare. Restenosis, and even sudden cardiac events, can occur and long-term surveillance is critical. Multi-institutional collaboration is vital to identify at-risk subpopulations and refine current recommendations for long-term management.

Abstract
The main objective of this article was to analyze prevalence data about myocardial bridging (MB) in published studies. To this purpose, we performed a meta-analysis of studies published in English literature that contained data about the prevalence of MB and its anatomical characteristics. The overall prevalence was 19% (CI: 17-21%); autopsy studies revealed an overall prevalence of 42% (CI: 30-55%), CT studies 22% (CI: 18-25%), and coronary angiography 6% (CI: 5-8%). Most bridges were located on the left anterior descending artery (82% overall, 63% on autopsy studies), had a mean thickness of 2.47 mm and a mean length of 19.3 mm. In conclusion, autopsy studies should be the gold standard in evaluating the actual prevalence of myocardial bridges, while in vivo high-resolution CT scanning should be preferred to coronary angiography studies.

Abstract
BACKGROUND Anomalous aortic origin of a coronary artery is a congenital cardiac condition that can be associated with increased risk of sudden death. To date, quality of life and exercise performance have not been evaluated in patients with this condition who do not undergo surgical repair. METHODS We carried out a cross-sectional analysis of patients with unoperated anomalous aortic origin of a coronary artery at our institution from 1 January, 2000 to 31 January, 2016. We prospectively assessed quality of life using standardised questionnaires. Medical records were reviewed for clinical and exercise stress test data. Statistical analyses were performed using Student's t-tests and Spearman's correlation coefficients. RESULTS In total, 56 families completed the questionnaires. The average age at enrolment was 14.7±6 years. The majority were male (n=44, 78.6%) and had interarterial anomalous right coronary artery (n=38, 67.9%). Patients had normal quality of life on the PedsQL 4.0 Report, Child Health Questionnaire Child Form 87, and SF-36v2. Their parents had normal quality of life on the PedsQL 4.0 Parent Report, but parents of exercise-restricted patients had decreased Physical Functioning, General Health Perception, Emotional Impact on Parent, and Physical Summary scores (p<0.001-0.048) on the Child Health Questionnaire Parent Form 50. CONCLUSIONS Patients with unoperated anomalous aortic origin of a coronary artery appear to have normal quality of life, but parents of exercise-restricted patients have decreased general health and emotional and physical quality of life scores. Improved counselling of families may be beneficial in this group. Future studies with more patients should evaluate quality of life and exercise performance over time.

Abstract
PURPOSE OF REVIEW To better understand the risk of sudden death from coronary anomalies. RECENT FINDINGS Most coronary anomalies are benign, but there are certain coronary anomalies that increase the risk of sudden cardiac death (SCD) in the young, notably anomalous aortic origin of a coronary artery from the wrong sinus. Previously, the risk of SCD attributed to certain coronary anomalies was felt to be quite high, as the risk assessment was based on autopsy series. Recent studies have shown that the risk attributed to anomalous coronary arteries is much lower than once believed. Risk appears to be highest with anomalous left coronary artery from the right sinus of Valsalva with interarterial course, notably when the young patient is participating in vigorous physical exertion, such as with competitive sports. SUMMARY Treatment strategies may include exercise restriction or surgical repair. Management decisions should be based on a complete understanding of the risk for SCD because of anomalous coronary arteries. Future directions should focus on better methods to risk stratify these pediatric patients.

Abstract
OBJECTIVE Isolated congenital coronary artery fistula is a rare condition, and the surgical experience for treating this condition is limited. METHODS This was a retrospective review of 47 patients who underwent surgical repair of isolated congenital coronary artery fistula from January 2001 to March 2015. RESULTS All but 1 patient presented with no symptoms. The median age at operation was 3.9 years (range, 0.4-15.2 years), and the median weight was 15.2 kg (range, 6.3-77.0 kg). Right coronary artery to right ventricle fistula was the most common pattern, which was present in 16 patients. Epicardial ligation without cardiopulmonary bypass was used to treat 4 patients, whereas cardiopulmonary bypass was used in the remaining 43 patients. Surgical techniques included transcoronary closure in 20 patients, transcameral or transpulmonary closure in 20 patients, a combination of both transcameral and transcoronary closure in 2 patients, and a conversion from transcameral closure to epicardial ligation in 1 patient. There were no deaths during our study period. Injury to the mitral valve occurred in 1 patient. Residual shunt was observed in 8 patients, 2 of which closed spontaneously during the follow-up. Extracardiac repair was associated with a higher risk of recanalization (P = .004). Freedom from recanalization was 89.4%, 85.1%, 83.0%, and 83.0% at discharge, 6 months, 1 year, and 5 years postsurgery, respectively. Two patients required transcatheter closure for residual shunts. CONCLUSIONS Surgical repair of isolated congenital coronary artery fistula in pediatric patients can be performed with low mortality and morbidity. Careful evaluation after surgery is necessary to monitor the occurrence of residual shunt.

Abstract
A number of criteria are used in the literature to describe high take-off coronary arteries, which can in part, explain the divide in the literature on the pathological significance of this anomaly. This study presents the anatomical variations of high take-off coronary arteries to draw attention to the possible clinical implications they may cause during angiography and other surgical procedures. The English Literature was searched to review high take-off coronary arteries. A high take-off coronary artery arising at least 1 cm in adults or 20% the depth of the sinus in children above the sinutubular junction, is considered of greater clinical relevance and was included in our meta-analysis. High take-off coronaries by other criteria was also included as part of the comprehensive review. Exclusion criteria were reports made in case studies or case reviews. The prevalence of high take-off coronary arteries in our study was 26 of 12,899 (0.202%). High take-off coronary arteries were found to originate up to 5 cm above the sinutubular junction. Right coronary arteries made up 84.46% of high take-off coronary arteries reported in the literature. Three (0.023%) cases that originated more than one centimeter above the sinutubular junction was associated with sudden cardiac death. This is a higher reported association than in studies that used other criteria for classification. It is important for clinicians to recognize the importance of correctly diagnosing high take-off coronary arteries in patients with coexisting cardiac morbidities so that suitable management plans can be developed.

Abstract
Anomalous origin of a coronary artery from the aorta is a potentially serious anomaly that occurs in about 0.1-0.2% of the population. This percentage is small; however, it translates into about 4000 annual births with these anomalies. The clinical presentation of these anomalies is rare, and hence most are and will remain asymptomatic. The various anatomic anomalies are described, with anomalous origin of the left coronary artery that then passes between the aorta and pulmonary artery being the most serious of these anomalies. The pathophysiology resulting from these anomalies is described, as are methods for identifying those who require treatment; however, we still do not know the best methods of determining which patients need treatment.
