Echocardiographic Screening of Anomalous Origin of Coronary Arteries in Athletes with a Focus on High Take-Off

Recommendations for cardiac screening and emergency action planning in youth football: a FIFA consensus statement

Sudden cardiac death is the leading medical cause of death among football players. Determining the optimal cardiac screening, the use of carefully selected medical assessments to detect underlying cardiovascular conditions associated with sudden cardiac arrest/death, is a desired objective of the Fédération Internationale de Football Association (FIFA) for football players of all ages. To date, cardiac screening recommendations in football have primarily focused on adult competitive players. Acknowledging its responsibility for player health worldwide, FIFA convened an international working group of cardiology and sports medicine experts to develop cardiac screening recommendations for youth football players. This group performed structured literature reviews and ultimately congregated in January of 2024, when recommendations were presented, scrutinised and judged using a systematic process. The final FIFA recommendations for youth cardiac screening include personal medical history, family medical history, focused physical examination and resting 12-lead electrocardiography. This document provides detailed rationale and clinical recommendations for youth cardiac screening and emphasises the importance of emergency action planning.

Clinical and CT Features, Clinical Management, and Decision on Sport Eligibility of Professional Athletes with Congenital Coronary Anomalies: A Case Series Study

BACKGROUND

Congenital coronary artery anomalies (CAAs) are a significant cause of sudden cardiac death and a key factor in determining athletes' eligibility for competitive sports. Their prevalence varies with diagnostic modalities and may present as asymptomatic or with life-threatening ischemic or arrhythmic events. This case series highlights the diverse manifestations of CAAs and the clinical approaches used to determine sports eligibility.

CASES DESCRIPTION

Five competitive athletes with different CAAs are presented. These cases include anomalous coronary origins, intramyocardial bridges, and coronary fistulas. Diagnostic tools, including coronary CT angiography (CCTA), cardiac magnetic resonance imaging (CMR), and stress tests, were essential in evaluating these anomalies and determining treatment strategies. In some cases, such as intramyocardial bridges, surgical intervention was necessary, while others required conservative management or exclusion from competitive sports.

CONCLUSIONS

CAAs require individualized care based on risk stratification through advanced imaging techniques and functional assessment. Surgical interventions are reserved for high-risk anomalies, while others may be managed conservatively. Early detection and tailored management are crucial for ensuring athletes' safety, and ongoing research is needed to optimize long-term outcomes.

The Spectrum of Coronary Artery Disease in Elite Endurance Athletes-A Long-Standing Debate: State-of-the-Art Review

Physical activity is recommended for the prevention of primary and secondary cardiovascular (CV) disease as it is linked to a number of health benefits, especially CV. However, recent research suggests that high-volume, long-term endurance exercise may hasten rather than slow the coronary atherosclerosis progression. This contentious theory has generated a great discussion and is still a major source of doubt when it comes to the clinical treatment of coronary artery disease (CAD) in athletes. CAD is the primary cause of sudden cardiac death in athletes over 35 years. Thus, recent studies evaluated the prevalence of CAD in athletes and its clinical and prognostic implications. Indeed, many studies have shown a relationship between endurance sports and higher volumes of coronary calcified plaque as determined by computed tomography. However, the precise pathogenetic substrate for the existence of an increased coronary calcification burden among endurance athletes remains unclear. Moreover, the idea that coronary plaques in elite athletes present a benign morphology has been cast into doubt by some recent studies showing potential association with adverse cardiovascular events. This review aims to analyze the association between physical activity and CAD, explaining possible underlying mechanisms of atherosclerotic progression and non-ischemic coronary lesions, focusing primarily on clinical and prognostic implications, multimodal evaluation, and management of CAD in endurance athletes.

Coronary artery anomalies: what are they? when to suspect? how to treat?-a narrative review

Background and Objective

In the literature have been widely discussed different classification criteria for coronary artery anomalies (CAAs), some authors have tried to categorize them only as "major" or "hemodynamically significant" anomalies versus "minor" or "not hemodynamically significant" ones. However, the most recent literature has concluded that all possible coronary anatomy should be taken into consideration in a comprehensive classification of CAAs. The aim of the article is to review the most recent literature regarding CAAs to provide a comprehensive overview of this challenging topic.

Methods

We propose a narrative overview of the most impactful and recent literature, synthetizing and re-elaborating the most important articles concerning CAAs.

Key Content and Findings

The important gap of knowledge on the specific characteristics of CAAs has led to a progressively increased interest of the current research in this field. Albeit their nature is still unclear, an increased awareness of their fatality is spreading among clinicians and the general population, mostly associated with their clinical relevance among young patients and athletes. On the other side, we do believe that clinical and hemodynamic repercussions are of crucial importance and should always be integrated to understand the true nature of this important pathology.

Conclusions

In the field of pediatric cardiology, CAAs are one of the most fascinating and studied subject. We propose a state-of-the art review to provide a comprehensive and systematic description and subsequently an approach to the epidemiological, pathophysiological, and clinical aspects of the most important CAAs in the pediatric population.

Coronary artery anomalies and the role of echocardiography in pre-participation screening of athletes: a practical guide

Transthoracic echocardiography is an essential and widely available diagnostic tool for assessing individuals reporting cardiovascular symptoms, monitoring those with established cardiac conditions and for preparticipation screening of athletes. While its use is well-defined in hospital and clinic settings, echocardiography is increasingly being utilised in the community, including in the rapidly expanding sub-speciality of sports cardiology. There is, however, a knowledge and practical gap in the challenging area of the assessment of coronary artery anomalies, which is an important cause of sudden cardiac death, often in asymptomatic athletic individuals. To address this, we present a step-by-step guide to facilitate the recognition and assessment of anomalous coronary arteries using transthoracic echocardiography at the bedside; whilst recognising the importance of performing dedicated cross-sectional imaging, specifically coronary computed tomography (CTCA) where clinically indicated on a case-by-case basis. This guide is intended to be useful for echocardiographers and physicians in their routine clinical practice whilst recognising that echocardiography remains a highly skill-dependent technique that relies on expertise at the bedside.

Anomalous right coronary artery originating from the aorta: a series of nine pediatric cases

BACKGROUND

To investigate the clinical manifestations, prognosis, and possibly related genes of anomalous right coronary artery originating from the aorta (ARCA-L) in children.

METHODS

This case series study included pediatric patients diagnosed with ARCA-L at the Department of Cardiology in Beijing Children's Hospital affiliated to Capital Medical University, between January 2017 and December 2019.

RESULTS

Nine pediatric patients (aged 3 months to 12 years, 4 boys) were included. Two cases presented with cardiac insufficiency as their primary manifestation, while the remaining seven had post-infection or post-exercise symptoms such as chest pain, chest tightness, long exhalation, lack of strength, and dizziness. Six patients displayed varying degrees of ST-T changes on the electrocardiograph, while two patients had a reduced left ventricular ejection fraction (LVEF) of 20-32% according to echocardiography. Multislice computed tomographic angiography confirmed the presence of ARCA-L in all patients. One patient underwent the unroofing technique. The remaining eight received conservative treatment. After a follow-up of 2-64 months, eight children had a good prognosis and survived. One child experienced sudden death due to aggravated heart failure. Whole exome sequencing revealed that one child tested negative, one had mutations in the RYR2 and LDB3 genes, and the remaining four patients had a mutation in the GDF1, LRP6, MEF2A, and KALRN genes, respectively.

CONCLUSIONS

ARCA-L in children might have a wide variation in clinical manifestations and a risk of sudden death. The occurrence of the disease might be associated with genetic defects.

Congenital coronary artery anomalies in sports medicine. Why to know them

The anomalous origin of a coronary artery (AOCA) is a challenging topic, due to its rarity, the complexity of the pathophysiological aspects, the clinical presentation (often silent), the difficulty of diagnosis, and the potential risk of causing acute cardiovascular events up to sudden cardiac death, particularly when triggered by heavy physical exercise or sport practice. Increasing interest in sport medical literature is being given to this topic. This paper reviews current knowledge of AOCAs in the specific context of the athletic setting addressing epidemiological and pathophysiological aspects, diagnostic work-up, sports participation, individual risk assessment, therapeutic options, and return to play decision after surgery.

Detection of anomalous aortic origin of a coronary artery (AAOCA) by echocardiogram: When does computed tomographic angiography add value?

BACKGROUND AND OBJECTIVE

There is limited literature comparing TTE and CCTA in children with suspected AAOCA. To determine the distribution of various coronary anomalies comparing TTE and CCTA data, and define the added value advanced imaging brings in clinical decision-making.

MATERIALS AND METHODS

Retrospective review of data was obtained in patients aged 0-18 years who underwent TTE and CCTA for suspected AAOCA. Patient demographics, CCTA and TTE findings, and interventions performed were recorded.

RESULTS

100 consecutive patients were included (60% male), mean age 11 years (7 days-18 years old). In 93 patients, CCTA detected 94 anomalous coronaries. Definitive coronary abnormality was reported on TTE in 77 patients; 76 of which were confirmed by CCTA, 1 patient was found to have a normal variant. Suspected anomalous origin was reported in 16 patients on TTE, 13 of which were abnormal on CCTA. The coronary origin was not seen on TTE in 6 patients; of these, 3 had AAOCA on CCTA and 3 had hypoplastic RCA with left dominant system. Only 1 patient who had a normal TTE was found to have AAOCA on CCTA. CCTA was better than TTE in defining ostial characteristics and the course of the anomalous coronary artery, and detecting myocardial bridge.

CONCLUSIONS

CCTA adds value in diagnosing AAOCA when the coronary origins are not well assessed or suspected anomalous origin is suggested on TTE. In addition, when a confident definitive diagnosis of AAOCA is reported on TTE, CCTA demonstrates better performance in determining additional features of AAOCA.

Screening of Coronary Artery Origin by Echocardiography: Definition of Normal (and Abnormal) Take-Off by Standard Echocardiographic Views in a Healthy Pediatric Population

Background: Echocardiographic screening of anomalous coronary artery origin is of increasing interest for children participating in sport activities. However, criteria to define normal coronary artery origins in children are poorly defined. Thus, the aim of the present investigation is to define the normal origin and angle of emergence of coronary arteries by echocardiography in healthy children. Materials and methods: The distances of the left main and right coronary artery (LMCA, RCA) origins from the aortic annulus were measured in the parasternal long-axis view (LAX). The angle of coronary artery emergence was measured in the parasternal short-axis view (SAX). Results: A total of 700 healthy subjects (mean age: 9.53 ± 5.95 years; range: 1 day−17.98 years) were prospectively enrolled. The distance of the RCA and LMCA from the aortic annulus correlated with body surface area, and nomograms (Z-scores) were generated. The RCA origin was below the sinotubular junction (STJ) in 605 patients (86.43%), at the STJ in 66 patients (9.43%), and above the STJ in 29 patients (4.14%). The LMCA origin was below the STJ in 671 patients (95.86%), at the STJ in 12 patients (1.71%), and above the STJ in 17 patients (2.43%). With respect to the RCA, an emergence angle < 18.5° in the SAX predicted a high take-off. with a sensitivity of 98.3% and a specificity of 93.1% (AUC 0.998). With respect to the LMCA, an emergence angle > 119.5° in the SAX predicted a high take-off, with a sensitivity of 70.6% and a specificity of 82.4% (AUC 0.799). Conclusion: This study establishes nomograms for LMCA and RCA origin in standard echocardiographic projections in healthy children.

The role of cardiac computed tomography in sports cardiology: back to the future!

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