Decreased Quality of Life in Children With Anomalous Aortic Origin of a Coronary Artery

Anatomical Variants of the Origin of the Coronary Arteries: A Systematic Review and Meta-Analysis of Prevalence

PURPOSE

The most common anomaly is an anomalous left coronary artery originating from the pulmonary artery. These variants can be different and depend on the location as well as how they present themselves in their anatomical distribution and their symptomatological relationship. For these reasons, this review aims to identify the variants of the coronary artery and how they are associated with different clinical conditions.

METHODS

The databases Medline, Scopus, Web of Science, Google Scholar, CINAHL, and LILACS were researched until January 2024. Two authors independently performed the search, study selection, and data extraction. Methodological quality was evaluated using an assurance tool for anatomical studies (AQUA). Pooled prevalence was estimated using a random effects model.

RESULTS

A total of 39 studies met the established selection criteria. In this study, 21 articles with a total of 578,868 subjects were included in the meta-analysis. The coronary artery origin variant was 1% (CI = 0.8-1.2%). For this third sample, the funnel plot graph showed an important asymmetry, with a p-value of 0.162, which is directly associated with this asymmetry.

CONCLUSIONS

It is recommended that patients whose diagnosis was made incidentally and in the absence of symptoms undergo periodic controls to prevent future complications, including death. Finally, we believe that further studies could improve the anatomical, embryological, and physiological understanding of this variant in the heart.

Trends in surgical management of anomalous aortic origin of the coronary artery over 2 decades

Objective

To evaluate outcomes of patients undergoing surgery for anomalous aortic origin of the coronary artery (AAOCA) at a tertiary care center and determine the influences of a coronary artery program on management strategies and outcomes.

Methods

This retrospective review of consecutive surgical patients who had isolated AAOCA at a tertiary care center between August 1, 1999, and October 31, 2022, compared patient characteristics, interventional timing, and surgical strategies before and after program inception in 2018. Comparisons between time periods and anatomical subgroups were performed using Fisher exact and Wilcoxon rank-sum tests.

Results

Of 149 surgical AAOCA patients, 102 (69%) had AAO of the right coronary artery. Compared with AAO of the left coronary artery (AAOLCA), AAO of the right coronary artery (AAORCA) was associated with greater athletic participation (intramural, varsity, and college-level) (74% vs 43%; P < .001) and preoperative functional imaging (72% vs 49%; P = .01), but were less likely to have ischemic changes on functional imaging (5% vs 23%; P = .03) or any postoperative complications (7% vs 19%; P = .04). Moderate or greater aortic insufficiency occurred postoperatively in 1 (1%) of AAORCA and 1 (3%) of AAOLCA patients. After the coronary artery program inception, there was an increase among patients with AAOCA undergoing preoperative computed tomography angiography (pre-2018: 39 out of 98 [40%] vs post-2018: 48 out of 51 [94%]; P < .001) and a decrease in isolated AAOCA unroofing procedures performed (30 [31%] vs 5 [10%]; P = .004).

Conclusions

Surgical management of AAOCA evolved over time, and can be achieved with low instance of postoperative aortic insufficiency. Establishment of a coronary artery program has streamlined care.

Management of Adults With Anomalous Aortic Origin of the Coronary Arteries: State-of-the-Art Review

As a result of increasing adoption of imaging screening, the number of adult patients with a diagnosis of anomalous aortic origin of the coronary arteries (AAOCA) has grown in recent years. Existing guidelines provide a framework for management and treatment, but patients with AAOCA present with a wide range of anomalies and symptoms that make general recommendations of limited applicability. In particular, a large spectrum of interventions can be used for treatment, and there is no consensus on the optimal approach to be used. In this paper, a multidisciplinary group of clinical and interventional cardiologists and cardiac surgeons performed a systematic review and critical evaluation of the available evidence on the interventional treatment of AAOCA in adult patients. Using a structured Delphi process, the group agreed on expert recommendations that are intended to complement existing clinical practice guidelines.

Sport resumption and quality of life after surgical correction of anomalous origin of a coronary artery from the opposite sinus

Objectives

We sought to assess the resumption of sport, exercise performances, and quality of life (QoL) in adults and children after surgical repair of anomalous coronary arteries originating from the opposite sinus (ACAOS).

Materials and methods

Patients who underwent surgical repair for ACAOS between 2002 and 2022 were retrospectively identified. Information about sports activity and exercise performance based on metabolic equivalents of task (METs) calculated at the last exercise stress test, were collected. QoL was assessed using age-appropriate questionnaires (Paediatric QoL Inventory, cardiac module version 3.0 for patients <18 years; SF-36 QoL Inventory for adults). Patients' METS and patients' QoL-scores were compared to reference population using the Wilcoxon test.

Results

45 patients were enrolled (males 71%, adults 49%, anomalous right coronary 84%). Median age at surgery was 15 years; median follow-up after surgery was 2.3 years [4 months-12 years]. All post-operative exercise stress tests were normal, METs and VO2 max patients' values did not differ from healthy children or adults (Exercise intensity: 12.5 ± 4.7 vs. 13.4 ± 2 METS, p = 0.3; VO2 max: 43.6 ± 16.6 vs. 46.9 ± 7 ml/kg/min, p = 0.37). For adults, QoL-scores were similar between ACAOS patients and controls. For children, there was no significant difference between the study patients' scores and those of the reference population, except for physical appearance proxy-report (p = 0.02).

Conclusion

In our study, the practice of sports, exercise stress testing and QoL were not adversely affected after ACAOS repair.

Decision making in anomalous aortic origin of a coronary artery

INTRODUCTION

There are many uncertainties surrounding anomalous aortic origin of a coronary artery (AAOCA) including the pathophysiology of sudden cardiac death, how to best risk stratify patients, how to best evaluate patients, who would benefit from exercise restriction, who should undergo surgical intervention, and which operation to perform.

AREAS COVERED

The goal of this review is to provide a comprehensive but succinct overview of AAOCA to help clinicians with the difficult task of navigating optimal evaluation and treatment of an individual patient with AAOCA.

EXPERT OPINION

Beginning in year 2012, some of our authors proposed an integrated, multi-disciplinary working group which has become the standard management strategy for patients diagnosed with AAOCA. A multi-disciplinary team with a focus on shared decision-making with the patients/families is likely necessary to optimize outcomes. Long-term follow-up and research are needed to improve our understanding of AAOCA.

Surgery for Anomalous Aortic Origin of a Coronary Artery (AAOCA) in Children and Adolescents: A Meta-Analysis

We conducted a systematic review and meta-analysis of the literature to assess the outcomes of surgery for the anomalous aortic origin of a coronary artery in children and young adults (<30 years). Thirteen publications were selected, including a total of 384 patients. Unroofing of the intramural segment was adopted in 92% (95% CI: 81%-98%) of cases, with pooled early and late mortality of 0% (95% CI: 0%-0.3%) and 0.1% (95% CI: 0%-1%), respectively. Reoperation for aortic regurgitation was anecdotal. Surgical management of anomalous aortic origin of coronary arteries can be achieved with excellent results in pediatric patients, but concerns remain about the durability of surgery.
