RESUMEN
BACKGROUND: Anomalous aortic origin of a coronary artery from the inappropriate sinus of Valsalva (AAOCA) is a rare congenital heart lesion. It is uncommon for patients with AAOCA to present with severe symptoms at a very young age. CASE PRESENTATION: We describe a very rare but critical presentation in a young infant with AAOCA that requires surgical repair and pacemaker placement. A three-month-old infant was referred because of syncope. Cardiac arrest occurred shortly after admission. The electrocardiogram indicated a complete atrioventricular block and a transvenous temporary pacemaker was implanted. A further coronary computed tomographic angiography (CTA) showed the anomalous origin of the right coronary artery from the left sinus of Valsalva. Coronary artery unroofing was performed due to an interarterial course with the intramural component, and a permanent epicardial pacemaker was implanted. The postoperative recovery was uneventful, and this patient was thriving and asymptomatic at the nine-month follow-up. However, the electrocardiogram still indicated a complete pacing rhythm. CONCLUSIONS: By timely diagnosis and treatment, this patient is successfully rescued. Although rare, AAOCA may be fatal even in infants.

A transseptal coronary artery course, also known as a transconal course, is an anomalous course of the left main coronary artery (LMCA) or the left anterior descending artery (LAD) through the conal septal myocardium. The conal septal myocardium is the posterior wall of the right ventricular outflow tract (RVOT), acting as a dividing myocardial wall between the subaortic and subpulmonary outflow tracts. The initial segment of a transseptal coronary artery has an extraconal course between the aorta and the RVOT cranial to the true intramyocardial segment. The transseptal coronary artery then emerges out of the conal septal myocardium at the epicardial surface on the lateral aspect of the RVOT. Many consider the transseptal coronary artery to be a benign entity. However, there are few case reports of severe cardiac symptoms such as myocardial ischemia, arrhythmia, and even sudden cardiac deaths due to potential coronary artery compression in the systolic phase.â In this article, we seek to describe the imaging findings of transseptal coronary artery course on coronary computed tomography angiography (CTA), discuss their clinical analysis, and briefly discuss the management of these lesions.

PURPOSE OF REVIEW: This review describes the presentation, diagnosis, and management of congenital coronary artery fistulas (CAFs) in adults. RECENT FINDINGS: CAFs are classified as coronary-cameral or coronary arteriovenous fistulas. Fistulous connections at the distal coronary bed are more likely to be aneurysmal with higher risk of thrombosis and myocardial infarction (MI). Medium-to-large or symptomatic CAFs can manifest as ischemia, heart failure, and arrhythmias. CAF closure is recommended when there are attributable symptoms or evidence of adverse coronary remodeling. Closure is usually achievable using transcatheter techniques, though large fistulas may require surgical ligation with bypass. Given their anatomic complexity, cardiac CT with multiplanar 3-D reconstruction can enhance procedural planning of CAF closure. Antiplatelet and anticoagulation are essential therapies in CAF management. CAFs are rare cardiac anomalies with variable presentations and complex anatomy. CAF management strategies include indefinite medical therapy, percutaneous or surgical CAF closure, and lifelong patient surveillance.

We aimed to characterize the ranges, temporal trends, influencing factors, and prognostic significance of postoperative troponin levels after congenital heart surgery. This single-center retrospective study included patients from 2006 to 2021 who had ≥ 1 postoperative troponin-T measurement collected within 96 h of congenital heart surgery (CHS). Patients were grouped as Anomalous Aortic Origin of the Coronary Artery-"AAOCA repair," or congenital heart surgery with "Other Coronary Interventions" other than AAOCA repair, or "No Coronary Intervention." In each group, information on concomitant surgery requiring one or more of the following-atriotomy, ventriculotomy, right ventricular muscle bundle resection, and/or septal myectomy-was collected. Clinical correlates of troponin values were analyzed in three postoperative windows: < 8, 8-24, and 24-48 h. The highest median [range] troponin levels (ng/mL) for the samples were 0.34 [0.06, 1.32] at < 8 h for "AAOCA repair," 1.35 [0.14, 12.0] at < 8 h for those undergoing CHS with "Other Coronary Interventions," and 0.87 [0.06, 25.1] at 8-24 h for those undergoing CHS with "No Coronary Interventions." Atriotomy was associated with higher median troponin levels in the AAOCA group at < 8 h (0.40 [0.31, 0.77] vs. 0.29 [0.17, 0.54], P = 0.043) and in the Other Coronary Intervention group at 8-24 h (1.67 [1.04, 2.63] vs. 0.40 [0.19, 1.32], P = 0.002). Patients experiencing major postoperative complications (vs. those who did not) had higher troponin levels in the AAOCA group as early as 8-24 h (0.36 [0.24, 0.57] vs. 0.21 [0.14, 0.33], P = 0.03). Similar findings were noted in the Coronary Intervention (2.20 [1.34, 3.90] vs. 1.11 [0.51, 2.90], P = 0.028) and No Coronary Intervention (2.2 [1.49, 15.1] vs. 0.74 [0.40, 2.34], P = 0.027) groups but earlier at < 8 h. In the AAOCA group, 2/18 (11%) troponin outliers experienced cardiac arrest in comparison to 0/80 (0%) non-outliers (P = 0.032). In the Other Coronary Intervention group, troponin outliers had longer median times to ICU discharge (10 vs. 4 days) and hospital discharge (21 vs. 10 days) (both P < 0.001). Postoperative troponin levels depend on a multitude of factors and may have prognostic value in patients undergoing congenital heart surgery with coronary interventions.

PURPOSE: To develop and validate a deep learning (DL)-model for automatic reconstruction for coronary CT angiography (CCTA) in patients with origin anomaly, stent or bypass graft. MATERIAL AND METHODS: In this retrospective study, a DL model for automatic CCTA reconstruction was developed with training and validation sets from 6063 and 1962 patients. The algorithm was evaluated on an independent external test set of 812 patients (357 with origin anomaly or revascularization, 455 without). The image quality of DL reconstruction and manual reconstruction (using dedicated cardiac reconstruction software provided by CT vendors) was compared using a 5-point scale. The successful reconstruction rates and post-processing time for two methods were recorded. RESULTS: In the external test set, 812 patients (mean age, 64.0 ± 11.6, 100 with origin anomalies, 152 with stents, 105 with bypass grafts) were evaluated. The successful rates for automatic reconstruction were 100% (455/455), 97% (97/100), 100% (152/152), and 76.2% (80/105) in patients with native vessel, origin anomaly, stent, and bypass graft, respectively. The image quality scores were significantly higher for DL reconstruction than those for manual approach in all subgroups (4 vs. 3 for native vessel, 4 vs. 4 for origin anomaly, 4 vs. 3 for stent and 4 vs. 3 for bypass graft, all p < 0.001). The overall post-processing time was remarkably reduced for DL reconstruction compared to manual method (11 s vs. 465 s, p < 0.001). CONCLUSIONS: The developed DL model enabled accurate automatic CCTA reconstruction of bypass graft, stent and origin anomaly. It significantly reduced post-processing time and improved clinical workflow.

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.

Objective: To analyze the diagnosis and surgical treatment of high-risk anomalous aortic origin of coronary artery (AAOCA). Methods: This is a retrospective case series study. From January 2016 to July 2023, 24 cases of high-risk AAOCA underwent surgical treatment in Department of Cardiac Surgery, Guangdong Provincial People's Hospital. There were 18 males and 6 females, operatively aged (M (IQR)) 13 (26) years (range: 0.3 to 57.0 years). They were confirmed by cardiac ultrasound and cardiac CT, all of which had anomalous coronary running between the aorta and the pulmonary artery. There were 15 cases of the right coronary artery from the left aortic sinus of Valsalva, 6 cases of left coronary artery from the right aortic sinus of Valsalva, 3 cases of the sigle coronary artery. Only 3 patients had no obvious related symptoms (2 cases were complicated with a positive exercise stress test and 1 case with other intracardiac malformations), 21 cases had a history of chest tightness, chest pain, or syncope after exercise. Three patients suffered syncope after exercise and underwent cardiopulmonary resuscitation (2 cases were treated with an extracorporeal membrane oxygenerator (ECMO)). The gap from the first symptom to the diagnosis was 4.0 (11.5) months (range: 0.2 to 84.0 months). The detection rate of coronary artery abnormalities suggested by the first cardiac ultrasound was only 37.5% (9/24). Seven patients were complicated with other cardiac diseases (4 cases with congenital heart defects, 2 cases with coronary atherosclerotic heart disease, 1 case with mitral valve disease). Results: All 24 patients underwent surgical treatment (23 cases underwent abnormal coronary artery unroofing, 1 case underwent coronary artery bypass grafting), and 5 patients underwent other intracardiac malformation correction at the same time. There were no death or surgery related complications in the hospital for 30 days after the operation. A patient with preoperative extracorporeal cardiopulmonary resuscitation was continuously assisted by ECMO after emergency AAOCA correction and had complications such as limb ischemia necrosis and renal dysfunction after the operation. During the follow-up of 2.2 (3.3) years (range: 1 month to 7.2 years), one patient who previously underwent percutaneous transluminal coronary angioplasty with a stent implant experienced significant postoperative symptomatic relief, and the other discharged patients had no related symptoms. Conclusions: The accurate rate of initial diagnosis for high-risk AAOCA is still low, but the risk of cardiovascular accidents is high. For sports-related chest pain and other symptoms, more attention should be paid to the detection of AAOCA, especially for adolescents. Exercise stress testing can be helpful in evaluating the cardiovascular risk of asymptomatic AAOCA. Instant surgical treatment can achieve satisfactory curative effects.

BACKGROUND: Anomalous coronary arteries are rare congenital variations with cases ranging from asymptomatic to life-threatening. Given the wide variability of coronary anomalies, it is challenging to predict their clinical consequences. Here, we present the 'malignant' variant - interarterial course of the left coronary artery between the aorta and pulmonary trunk - given the highest risk of sudden cardiac death among the various coronary anomalies. CASE PRESENTATION: Our case presents a 22-year-old male presenting to the emergency department after a syncopal episode that occurred while the patient was driving a motor vehicle. Initial Computed Tomography (CT) of the chest performed as part of the trauma work-up revealed a rare case of an anomalous origin of the left main coronary artery (LMCA) originating from a common ostium with the right coronary artery (RCA). The LMCA was found to have a malignant course, as it was positioned between the aorta and pulmonary artery. Given the high risk of sudden cardiac arrest with this congenital variant, the patient underwent coronary artery bypass grafting. CONCLUSION: Anomalous coronary arteries remain the second leading cause of sudden cardiac death in young adult patients. The risk of sudden cardiac death depends on the congenital variant of the anomalous coronary artery as well as the course these vessels take. This case highlights a rare congenital variant featuring both the LMCA and RCA originating from a common ostium, with the LMCA having a malignant course, a variant with the highest risk of sudden cardiac death.

Patients with anomalous aortic origin of a coronary artery (AAOCA) require imaging to clarify the multiple potential anatomic sites of obstruction (fixed or dynamic). Once repaired, the pathway of blood to the myocardium must not encounter: (1) intrinsic ostial stenosis, (2) obstruction from compression or distortion near the commissure or the intercoronary pillar, (3) stenosis where the artery exits the aortic wall (due to an acutely angled "take-off"), (4) compression due to a pathway between the great vessels, (5) stenosis or compression along an intramural course, or (6) compression due to an intramuscular (intraseptal/intraconal) course. Detailed anatomic evaluation of each of these locations allows the surgeon to select an appropriate repair strategy, and each of these abnormal anatomic features should be "matched" with a particular surgical correction. We speculate that the most common surgical repair, unroofing with or without tacking, is often inadequate, as in isolation, it may not allow for correction with a large orifice from the appropriate sinus, without an interarterial course. While the evidence base is insufficient to call these recommendations formal guidelines, these recommendations should serve as a basis for further validity testing, and ultimate evolution to more granular guidelines on AAOCA management.

Objective of this study is to summarize surgical outcomes of patients with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in a single center. The clinical data of 89 children undergoing surgical treatment in Beijing Children's Hospital from January 2007 to January 2022 were retrospectively analyzed. seven patients underwent ECMO support for acute left heart failure after operation, and 2 patients were discharged after weaning successfully. Eight patients died in the early postoperative period, all of them were infants, of which 5 patients underwent ECMO support, 2 patients died of cerebral hemorrhage, 2 patients died of multiple organ dysfunction, and 4 patients died of left heart failure. Three patients died late, 3 patients were lost to follow-up, and 78 patients (96.3%) completed long-term follow-up. A logistic regression model multivariate analysis showed that postoperative moderate or severe mitral regurgitation (MR) (OR 26.948 P = 0.024) and prolonged aortic cross-clamp time (OR 1.038 P = 0.050) were independent risk factors of early mortality. Compared with the Non-MVP group (20/36), the MVP group (patients with moderate or severe MR who underwent MVP at the same time) (16/36) had more significant improvement in early postoperative LEVEF [(50.68 ± 13.85)% vs (40.50 ± 13.58)% P = 0.033] and had a lower proportion of moderate or severe MR after operation (2/16 vs 11/20 P = 0.014). Children with ALCAPA can obtain a good prognosis by reconstructing the blood supply of both coronary arteries. Mitral valvuloplasty (MVP) is more helpful in improving the prognosis of children with moderate or severe MR and mitral valve structural disease. Reasonable placement of ECMO can help reduce the mortality of critically ill children after operation, but be alert to complications in the central system.

Anomalous aortic origin of the left coronary artery from an incorrect aortic sinus has been reported as the second most common causes of sudden cardiac arrest in young athletes. Intramural course of the proximal left coronary artery is considered a high-risk morphology. It is associated with a slit-like ostium and elliptical shape of the proximal artery. In this case, all pre-operative cardiac images demonstrated a round ostium and round luminal shape of the left coronary artery, which suggested no evidence of intramural course. On intraoperative inspection, although the ostium and proximal left coronary artery appeared round, the patient had a long intramural course of the left coronary artery which our surgeons performed a successful unroofing procedure. The post-operative images showed a patent new ostium from the correct aortic sinus. These findings are very unusual and proved that we should not exclude intramural course even in the absence of a slit-like ostium and elliptical shape of the proximal left coronary artery.

Coronary artery fistulas are rare, but one of the most common forms of congenital coronary abnormalities. These patients are often diagnosed incidentally undergoing coronary angiography, but with the advent of novel cardiac imaging tools, there is an increasing rate of detection as well as transcatheter management of these fistulas. Our case is unusual in a way that it involved a combination of two separate coronary artery fistulas arising from both the coronary systems draining into the same site.

Coronary artery fistula is a rare but well-documented complication of right ventricular endomyocardial biopsy, particularly in the adult population. Typically, these fistulae never reach clinical or hemodynamic significance, but some may cause coronary steal and ventricular dysfunction. We report a case of a significant coronary artery fistula requiring device closure in the cardiac catheterization laboratory with subsequent improvement of clinical symptoms and cardiac function.

BACKGROUND: Anomalous aortic origin of the left coronary artery with intraseptal course is a rare coronary anomaly associated with an increased risk of myocardial ischaemia. The role and techniques for surgical intervention are evolving, with numerous novel surgical techniques for this challenging anatomy reported in the last 5 years. We report our single-centre experience with surgical repair of intraseptal anomalous left coronary artery in the paediatric population, including clinical presentation, evaluation, and short- to mid-term outcomes. METHODS: All patients with coronary anomalies presenting to our institution undergo standardised clinical evaluation. Five patients aged 4 to 17 years underwent surgical intervention for intraseptal anomalous aortic origin of the left coronary artery between 2012 and 2022. Surgical techniques included coronary artery bypass grafting (n = 1), direct reimplantation with limited supra-arterial myotomy via right ventriculotomy (n = 1), and transconal supra-arterial myotomy with right ventricular outflow tract patch reconstruction (n = 3). RESULTS: All patients had evidence of haemodynamically significant coronary compression, and three had evidence of inducible myocardial ischaemia pre-operatively. There were no deaths or major complications. Median follow-up was 6.1 months (range 3.1-33.4 months). Patients who underwent supra-arterial myotomy (with or without reimplantation) had improved coronary flow and perfusion based on stress imaging and catheterisation data. CONCLUSIONS: Surgical approaches to intraseptal anomalous left coronary artery with evidence of myocardial ischaemia continue to evolve, with new techniques demonstrating promising improvement in coronary perfusion. Further studies are warranted to determine long-term outcomes and refine indications for repair.

INTRODUCTION: In this study, we present a case of directing persistent left superior vena cava drainage into the unroofed coronary sinus to the right atrium in a patient with tetralogy of Fallot and coronary sinus orifice atresia without innominate vein. CASE REPORT: A 16-month-old boy diagnosed with tetralogy of Fallot was admitted. Following intracardiac repair, the left superior vena cava was divided from the left atrial junction, passed through under the ascending aorta and anastomosed to the right superior vena cava. CONCLUSION: To our knowledge, this is the first patient reported with persistent left superior vena cava, unroofed coronary sinus, coronary sinus orifice atresia, and tetralogy of Fallot. The extracardiac direct anastomosis technique was used successfully to direct persistent left superior vena cava to the right atrium without any post-procedure complications.

A coronary artery fistula usually originates in the right coronary artery and often opens into the right ventricle. In approximately 50% of cases with a main pulmonary artery opening, aberrant blood vessels originate from both coronary arteries. Only a few cases of both coronary and bronchial artery-pulmonary artery fistulas have been reported. The patient was an 83-year-old man. Echocardiography showed severe aortic stenosis, while coronary angiography revealed aberrant vessels from both coronary arteries to the pulmonary artery. The right heart catheterization revealed a 26% left-to-right shunt ratio and a pulmonary/body blood flow ratio (Qp/Qs) of 1.36. MDCT scan confirmed that the aberrant vascular plexus originating from both coronary arteries was connected to the bronchial artery. We performed surgery on the patient, replacing the aortic valve and resecting the coronary arteriovenous fistulas. On the 11th postoperative day, the shunt had disappeared, as evidenced by a 1.2% left-toright shunt ratio and a Qp/Qs of the right heart catheterization of 1.02. The patient progressed uneventfully and was discharged on the 25th postoperative day.

Anomalous origin of the coronary artery is a rare congenital malformation that can cause myocardial ischemia and arrhythmia in patients with or without atherosclerotic lesions. We present a case of aortic stenosis (AS) and coronary artery stenosis complicated by anomalous origin of the right coronary artery (RCA) from the aortic valve sinus and its intramural course. The patient was a 66-year-old woman who was diagnosed with AS 4 years prior, and scheduled for surgery owing to gradual progression of stenosis. Preoperative coronary angiography revealed an abnormal origin of the RCA, and during the surgery, the RCA was found located within the aortic wall close to the aortotomy. Thus, bypass surgery was performed using a great saphenous vein, to prevent ischemia of the RCA territory. The patient had good intraoperative and postoperative course, and a coronary computed tomography scan clearly showed the reconstructed RCA.

BACKGROUND: Anomalous aortic origin of the coronary artery (AAOCA) refers to a congenital abnormality of the origin and/or course of a coronary artery that arises from the aorta. It can be classified according to the sinus from which the coronary artery arises. The most common type is an anomalous origin of the right coronary artery. CASE PRESENTATION: Herein, we report a 7-year-old male that was diagnosed with AAOCA. Although the patient had not complained of obvious symptoms before the onset, echocardiography showed that the left coronary artery originated from the noncoronary sinus at an anatomical location. CONCLUSION: AAOCA is a rare congenital disease that often causes a sudden death in young athletes. Originating from the noncoronary sinus at the level of the sinotubular junction in the anomalous origin of the left coronary artery is even more rare which is presented in this case. Surgical intervention should be actively performed if the patient has symptoms or if the anatomy is complex.
