ABSTRACT
Objective:
To describe the clinical features and prognosis of congenital anomalous origin of coronary artery(AOCA) in children to increase our understanding of the disease.Methods:
This retrospective study included children diagnosed with AOCA using computed tomography coronary angiography(CTCA) admitted to the Department of Cardiology, Beijing Children′s Hospital, Capital Medical University, from January 1, 2014 to December 31, 2019.The clinical presentations, laboratory results, imaging analyses, treatments, and prognoses of these patients were analyzed.Results:
A total of 208 children, including 105 boys and 103 girls, we evaluated the ages(9.03±4.18)years old with AOCA.Of these, 157 cases(75.5%) presented with cardiac symptoms, such as chest tightness, palpitations, dizziness, syncope, fatigue, and decreased endurance.Three cases(1.4%) had atypical symptoms of paroxysmal crying, dyspnoea and cyanosis, and 48 cases(23.1%) were asymptomatic.Levels of serological markers of myocardial injury were elevated in 59 cases(28.4%), and 140 cases(67.3%) had predominant ST-T abnormalities on electrocardiograms.Transthoracic echocardiography identified 27 cases (13%) with cardiac enlargement and ten cases(4.8%) with left ventricular systolic dysfunction.There were 126 cases(60.6%) with the anomalous origin of the left coronary artery revealed by CTCA, 50 cases(24.0%) with the anomalous origin of the right coronary artery and 32 cases(15.4%) with bilateral coronary arteries of anomalous origin.Five children underwent surgical treatment, and the remaining 203 children were treated conservatively with drugs.The whole group was successfully treated, and no death case was recorded during the follow-up period.Conclusion:
AOCA may cause different degrees of myocardial ischemia.Diverse clinical presentations and diagnostic limitations of transthoracic echocardiography often lead to missed diagnosis or misdiagnosis.In contrast, CTCA has high diagnostic accuracy and can be used to identify the location and course of the coronary ostia.Hence, the management of AOCA should be tailored on a case-to-case basis, taking into consideration of the specific type of coronary origin, with surgical intervention being warranted if necessary.
