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
Congenital coronary anomalies are not an infrequent occurrence and their clinical presentation typically occurs during early years, though may be manifested only in adulthood. In the setting of anomalous aortic origin of a coronary artery, this is particularly concerning as it inflicts sudden loss of healthy young lives. Risk stratification remains a challenge and so does the best management decision-making in these patients, particularly if asymptomatic. Standardized approach to evaluation and management, with careful data collection and collaboration among centers, will likely impact future outcomes in this patient population, thus allowing for exercise participation and healthier lives.

Computed tomography angiography (CTA) of anomalous aortic origin of a coronary artery (AAOCA): Which measurements are accurate and reliable? J Cardiovasc Comput Tomogr 2023; 17:130-137. [PMID: 36804387 DOI: 10.1016/j.jcct.2023.02.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 02/03/2023] [Accepted: 02/06/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND The variation and accuracy of computed tomography angiography (CTA) features of anomalous aortic origin of a coronary artery (AAOCA) have not been completely characterized. We evaluated anomalous right (AAORCA) and left (AAOLCA) coronary arteries by CTA, with an emphasis on reproducibility, comparison with surgical measurements, and effect of nitroglycerin. METHODS CTAs were interpreted for location of coronary origin & exit from the aorta, course, and dominance; minor & major diameters of the proximal & distal coronaries; shape of orifice; and intramural length. Relationships between vessel measurements, body surface area (BSA), and nitroglycerin use were evaluated. Comparisons between CTA and surgical measurements included intramural length, surgical probe size pre-intervention vs. CTA proximal AAOCA diameter, and surgical probe size post-intervention vs. CTA distal AAOCA diameter. RESULTS Of 104 patients [81 (78%) AAORCA], all but 1 were intramural. Compared to AAOLCA, AAORCA patients were more likely to have a high origin (91% vs. 31%, p < 0.01), and slit-like orifice (58% vs. 26%, p < 0.01). When CTAs with nitroglycerin were compared to those without, no difference in proximal AAOCA dimensions was identified; however distal AAOCA and normal-origin coronary dimensions were larger in scans with nitroglycerin. Aside from slit-like orifice, reliability of coronary CTA measurements, including proximal AAOCA minor diameter and intramural length, was moderate to good between readers. In a subgroup of 54 patients, proximal AAOCA minor diameter and intramural length had good agreement and correlation with surgery. CONCLUSION Proximal AAOCA dimensions and intramural length are reproducible variables. The lack of difference in proximal AAOCA dimensions with nitroglycerin may reflect abnormal vessel mechanics. Multicenter studies are an important next step in understanding the generalizability of our findings.

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
Anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) are a challenge because of their various anatomic and clinical presentation. Although the prevalence is low, the absolute numbers of detected ACAOS are increasing because of the growing use of noninvasive anatomical imaging for ruling out coronary artery disease. As evidence-based guidelines are lacking, treating physicians are left in uncertainty for the optimal management of such patients. The sole presence of ACAOS does not justify surgical correction, and therefore a thorough anatomic and hemodynamic assessment is warranted. Invasive and noninvasive multimodality imaging provides information to the clinical question whether the presence of ACAOS is an innocent coincidental finding, is responsible for the patient's symptoms, or even might be a risk for sudden cardiac death. Based on recent clinical data, focusing on the pathophysiology of patients with ACAOS, myocardial ischemia is dependent on both the extent of fixed and dynamic components, represented by anatomic high-risk features. These varying combinations should be considered individually in the decision making for the different therapeutic options. This state-of-the-art review focuses on the advantages and limitations of the common contemporary surgical, interventional, and medical therapy with regard to the anatomy and pathophysiology of ACAOS. Further, we propose a therapeutic management algorithm based on current evidence on multimodality invasive and noninvasive imaging findings and highlight remaining gaps of knowledge.

Abstract
OBJECTIVES Timing and method of surgical reconstruction for non-sclerotic proximal coronary artery stenosis, occuring de-novo or post coronary artery transfer, are evolving. We have pursued a technique of anatomical reconstruction of ostial and short segment proximal coronary artery stenosis and atresia in children, using patch plasty or interposition vein graft. Herein, we discuss the medium- to long-term outcome. METHODS Nine consecutive children undergoing ten left main coronary artery reconstructions using autologous great saphenous vein patch (n = 4), autologous pericardium (n = 4), xenopericardium (n = 1) or great saphenous vein interposition graft (n = 1) were retrospectively analysed. Complementary wedge resection of the stenotic coronary ostium was performed in chronic cases. RESULTS The aetiology of coronary artery stenosis was post arterial switch operation (n = 6), Takayasu`s arteritis (n = 1), idiopathic left main coronary artery atresia (n = 1) and anomalous origin of the left coronary artery from the pulmonary artery (n = 1). Median age and weight at operation were 0.15 (range 0.01-13.1) years and 4.4 (range 3 -13.1) kilograms, respectively. Survival was 100% at median follow-up of 12.6 (range 1-19.2) years. All patients showed normal left ventricular ejection fraction on transthoracic echocardiogram. In one patient, kinking of the proximal left circumflex artery resulted in non-significant obstruction. In all other cases, follow-up catheter angiography revealed unobstructed coronary arteries. Cardiac magnetic resonance tomography showed no significant perfusion deficit in any child. CONCLUSIONS Anatomical reconstruction of the proximal left coronary artery using autologous saphenous vein may allow optimal restoration of physiological coronary blood flow, keeping the option of future coronary bypass operation open.

Abstract
BACKGROUND Coronary artery anomalies (CAAs) are rare congenital malformations with different clinical presentations and pathophysiological mechanisms. These anomalies are frequently the cause of sudden death in young patients. Most CAAs are incidental findings owing to the lack of symptoms; however, they may be associated with acute coronary syndrome in rare cases. CASE REPORT We describe the case of a 47-year-old man who presented with a 1-day history of progressive typical chest pain and elevated troponin levels. The patient underwent a coronary angiography, which unveiled the anomalous origin of the left main coronary artery arising from the right coronary artery, with an interarterial course between the ascending aorta and the pulmonary artery, without coronary artery disease. Coronary computed tomography angiography confirmed the CAA and its relationship with the symptoms. An uneventful coronary artery bypass graft was undertaken, and at the 1-year follow-up, the patient was asymptomatic, with a normal stress test. CONCLUSIONS This case depicts the presentation of atypical acute coronary syndrome in a young patient with a rare CAA. In such patients, coronary angiography and coronary computed tomography angiography are essential tools to confirm the diagnosis and to determine treatment. Although controversial, in young individuals presenting CAA with an interarterial course, such as the left main coronary artery arising from the right coronary artery, coronary artery bypass graft may be an important treatment option to avoid sudden death in the future.

Abstract
Introduction: Anomalous aortic origin of a coronary artery (AAOCA) from the opposite sinus of Valsalva is a rare congenital abnormality. Computed tomography angiography (CTA) is primarily used as a diagnostic tool to evaluate the anatomy and identify potentially malignant AAOCA variants. Limited data is available on the role of CTA during postoperative follow-up. We aimed to develop an objective CTA derived parameter for diagnostic evaluation and follow-up after surgical correction of AAOCA and correlate the anatomical features to the postoperative outcome. Methods: All consecutive patients who underwent surgical repair of AAOCA from 2001 to 2018 and had pre and postoperative CTA imaging available were included. A retrospective analysis of the pre- and postoperative CTA and the outcomes was performed. The origin and course of the anomalous coronary artery and the ostial dimensions were evaluated and correlated with restenosis of operated coronary artery. To allow an accurate evaluation of the effective orifice area at diagnosis and after surgical repair we deduce and propose a new parameter—the coronary triangulated orifice area (CTOA). Results: Out of the 54 patients who underwent surgical treatment for AAOCA, 11 fulfilled the inclusion criteria. The median follow-up was 19 months [IQR 3;42]. The mean age at surgery was 41 ± 16 years, with six patients (55%) being male. Postoperatively, the angle between the proximal coronary artery and the aortic wall increased from 20 ± 5° to 28 ± 9° (p < 0.01) and ostial diameter in the transversal plane increased from 4.1 ± 2.5 mm to 6.2 ± 2.7 mm (p < 0.01). The median CTOA increased significantly from 1.6 mm2 [IQR 0.9;4.9] to 5.5 mm2 [IQR 3;11.8] (p < 0.005). During follow-up, in three patients a restenosis of the operated coronary artery was suspected. In these patients, the CTOA only showed a limited postoperative increase of ≤ 1.4 mm2. Conclusions: CTA can play an important role in the evaluation of the pre- and postoperative anatomy in AAOCA patients. CTOA may be of use in conjunction with the acute angle take-off and ostial diameter order to comprehensively evaluate the operated ostium after unroofing or patch angioplasty.

Abstract
Anomalous aortic origin of a coronary artery (AAOCA) is reported as the second leading cause of sudden cardiac death in otherwise healthy young individuals. Several surgical studies have reported a shallow operative risk, describing repair as safe and effective with short or medium-term follow-up. However, surgical repair can also be associated with a high risk of complications. Numerous repair techniques have been described in the literature, but each technique's indications and limitations are often not well-understood or understated. Since explicit technical knowledge of the most appropriate surgical technique is highly desirable, we sought to thoroughly and clearly outline the safeguards and pitfalls of the most common surgical techniques used to repair AAOCA.

Abstract
BACKGROUND Anomalous coronary artery originating from the opposite sinus of Vasalva with interarterial course (ACAOS-IAC) is associated with sudden cardiac death (SCD) in young athletes. If identified in adulthood prognosis is usually more benign, resulting in a dilemma regarding revascularization. METHODS This is a retrospective observational single-center study, including adults with ACAOS-IAC. Medical records between 2012 and 2019 were reviewed for management approach, mortality, cardiac death and coronary related adverse events. Coronary computed tomographic angiography (CCTA) were reviewed. We provide a literature review in regard to clinical outcome. RESULTS We identified 40 patients with ACAOS-IAC (mean age 51). Presentation was acute in 7/40 (18%). Ischemia detection with single photon emission tomography (SPECT), cardiac magnetic resonance (CMR) or dobutamine stress echocardiography were performed in 25/40 (63%) patients. Ischemia in the vascular territory of the anomaly was present in 2/25 (8%). In 39/40 (98%) patients were treated expectative. During median follow-up of 2.7 years (IQR 1.5-5.3) no cardiovascular death was observed. Mortality occurred in 1/40 (3%) and coronary related adverse events in 2/40 (5%). We identified 20 studies describing 1194 patients. Revascularization was performed in 376/1154 (32.6%) patients. Mortality stratified for clinical management was 23/431 (5.3%) in the non-revascularization versus 16/253 (6.3%) in the revascularization group during 4.0 years follow-up (weighted median). Cause of death was cardiovascular in 10/596 (1.7%) in 4.2 years (weighted median) follow up. CONCLUSIONS Both revascularization and non-invasive management have good prognosis in adults with ACAOS-IAC during early follow up. There is need for guidelines and long-term surveillance.

Outcomes in anomalous aortic origin of a coronary artery after surgical reimplantation. J Thorac Cardiovasc Surg 2021; 162:1191-1199. [PMID: 33541731 DOI: 10.1016/j.jtcvs.2020.12.100] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 11/19/2020] [Accepted: 12/19/2020] [Indexed: 10/22/2022]
Abstract
OBJECTIVE Anomalous aortic origin of a coronary artery (AAOCA) can be associated with myocardial ischemia and sudden cardiac arrest. We compared outcomes data of patients who underwent transection and reimplantation (TAR) and patients who underwent an unroofing. METHODS Patients who presented to the Coronary Artery Anomalies Program were evaluated and managed following a standardized approach. Anatomy was determined using computed tomography angiography, myocardial perfusion using advanced stress imaging, and surgical intervention according to anatomic features. RESULTS Sixty-one patients underwent surgical repair of AAOCA between 2012 and 2019: 16 (26%) patients underwent TAR of the anomalous coronary without an aortic button and 45 (74%) patients underwent coronary unroofing. Compared with patients who underwent an unroofing, patients who underwent TAR had similar intramural length (5 mm with interquartile range of 4-7.7 vs 6 mm with interquartile range of 5-7; P = .6). One patient with an anomalous right coronary underwent coronary artery bypass grafting after TAR because of persistent postoperative ischemic changes. One patient with unroofing of an anomalous left coronary artery presented with recurrent aborted sudden cardiac death and underwent subsequent TAR, without further events. At last follow-up, 15 of 16 patients (94%) who underwent TAR and 42 of 45 (93%) patients who underwent an unroofing were released to unrestricted exercise activities. CONCLUSIONS Coronary artery TAR is a useful surgical alternative for AAOCA when there is a course below the commissure, when unroofing does not relocate the ostium to the appropriate sinus, or when unroofing results in compression by the intercoronary pillar.

Abstract
OBJECTIVES It remains unclear when sudden cardiac event risk outweighs surgical risk for patients with anomalous aortic origin of a coronary artery. The Congenital Heart Surgeons' Society sought to characterize the surgical risks by determining the techniques, complications, and outcomes of repair. METHODS Between January 2000 and September 2018, 682 patients with anomalous aortic origin of a coronary artery aged 30 years or less were enrolled. Demographic, morphologic, operative, imaging, and ischemia-related data were analyzed. RESULTS There were 395 of 682 (57%) surgical patients (45 centers, median follow-up 2.8 years). In addition to primary repair (87% unroofing, 26% commissural manipulation), 13 patients had 15 coronary-related reoperations. Of 358 patients with pre/postoperative aortic insufficiency assessment, 27 (8%) developed new mild or greater aortic insufficiency postoperatively, and 7 (2%) developed new moderate or greater aortic insufficiency. Freedom from mild aortic insufficiency differed in those with versus without commissural manipulation (85%/91% at 6 months, 83%/90% at 1 year, and 77%/88% at 3 years, respectively) (P = .05). Of 347 patients with preoperative/postoperative ejection fraction, 6 (2%) developed new abnormal ejection fraction (<50%) within 30 days of surgery which persisted. Although 64 of 395 patients (16%) had preoperative ischemia, after surgery 51 of 64 patients (80%) no longer had ischemia (13 = new postoperative ischemia, P < .0001). Four patients died postoperatively (preoperatively 2 asymptomatic, 1 symptomatic, 1 in extremis). Composite surgical adverse event rates were 7% to 13% in the entire cohort (increasing/decreasing by presentation/anatomy/repair strategy). CONCLUSIONS Anomalous aortic origin of a coronary artery surgery may relieve ischemia with low mortality; however, it can result in a variety of important morbidities, varying by the group evaluated. Strategies avoiding commissural manipulation may decrease the risk of developing aortic insufficiency. Understanding these risks should inform surgical decision-making and support the need for standardized assessment and management.

Abstract
We describe a case of an adult patient with mitral valve regurgitation and the anomalous origin and course of the left circumflex coronary artery. Use of a ringless procedure or a microinvasive approach, such as transapical neochordae implantation, would have possibly avoided a life-threatening post-operative complication.

Abstract
OBJECTIVES Although surgical repair of an anomalous aortic origin of the coronary artery has low operative mortality, longer-term risk of ischemia and aortic regurgitation remains concerning. We routinely perform aortic commissure resuspension after unroofing and sought to evaluate the outcomes with regard to aortic valve competence, symptoms, and signs of ischemia with this approach. METHODS Twenty-six consecutive patients who received the unroofing procedure for anomalous aortic origin of the coronary artery (10 left; 16 right) between 2004 and 2016 were reviewed. In addition to complete unroofing of the intramural coronary, patients early in the cohort (n = 9) received unroofing only, and aortic commissural resuspension was performed routinely in the subsequent patients (n = 17). Outcomes between commissural resuspension versus no commissural resuspension were compared. The occurrence of mild and greater aortic regurgitation was assessed using a time-to-event analysis after varying lengths of time. Commissural resuspension was considered as the predictor, and the groups were compared using a log-rank test. RESULTS There was no operative mortality. One patient in the no commissural resuspension group died 10 years later of prosthetic aortic valve endocarditis (aortic valve replacement 7 years after unroofing). The follow-up duration was 6.9 years (4.9-9.1) and 3.7 years (2.1-4.3) in the no commissural resuspension and commissural resuspension groups, respectively (P = .001). Available postoperative exercise stress test data (n = 14) revealed that 50% had an endurance level at the 25th percentile or greater for age. After a median follow-up of 1.9 years (3 months to 10.6 years), no patient in the commissural resuspension group had aortic regurgitation, whereas 6 of 9 patients (67%) in the no commissural resuspension group had stable but mild or greater aortic regurgitation. Time-to-event analysis with the primary event of occurrence of mild or greater aortic regurgitation showed significantly higher freedom from the occurrence of aortic regurgitation in the commissural resuspension group (P = .035). CONCLUSIONS Surgical repair of an anomalous aortic origin of the coronary artery can be performed with excellent early and midterm outcomes. Routine commissural resuspension of the aortic valve may lead to a lower rate of aortic valve regurgitation without increasing the risk of ischemia.

Abstract
Anomalous aortic origin of coronary arteries (AAOCA) is a congenital disease that can lead to cardiac ischemia during intense physical activity. Although AAOCA is responsible for sudden cardiac death (SCD) among young athletes and soldiers, the mechanisms underlying the coronary occlusion during physical effort still have to be clarified. The present study investigates the correlation between geometric features of the anomaly and coronary lumen narrowing under aortic root dilatations. Idealized parametric computer-aided designed (CAD) models of the aortic root with anomalous and normal coronary are created and static finite element (FE) simulations of increasing aortic root expansions are carried out. Different coronary take-off angles and intramural penetrations are investigated to assess their role on coronary lumen narrowing. Results show that increasing aortic and coronary pressures lead to lumen expansions in normal coronaries, particularly in the proximal tract, while the expansion of anomalous coronary is impaired especially at the ostium. Concerning the geometric features of the anomaly, acute take-off angles cause elongated coronary ostia, with an eccentricity increasing with aortic expansion; the impact of intramural penetration of coronary on its luminal narrowing is limited. The present study provides a proof of concept of the biomechanical reasons underlying the lumen narrowing in AAOCA during aortic expansion, promoting the role of computational simulations as a tool to assess the mechanisms of this pathology.

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.
