ABSTRACT
Anomalous aortic origin of a coronary artery is a rare abnormal coronary artery development disease, which affects myocardial blood perfusion in the absence of significant coronary artery stenosis. Such patients have a high risk of sudden death, and their disease progresses rapidly, and their clinical manifestations are easily confused with myocardial diseases. We report a case of a 13-year-old young patient whose diagnosis was confirmed, the condition was stabilized at an early stage, and the abnormal coronary structure was corrected by coronary decapitation through a multidisciplinary combination of cardiology, cardiac surgery, ICU, and imaging. This article focuses on the diagnosis and treatment of these patients.
ABSTRACT
Anomalous aortic origin of a coronary artery is a rare congenital anomaly that can cause myocardial ischemia and ventricular arrhythmia. This disease initially manifests as cardiac arrest in half of patients. The indications and surgical strategy remain unclear, especially in patients who are asymptomatic and have poor ischemic findings. We report a surgical strategy to treat anomalous aortic origin of the right coronary artery. A 47-year-old man with a chief complaint of chest tightness was diagnosed with anomalous aortic origin of the right coronary artery, which branches from the left sinus of Valsalva and runs an inter-arterial course. Although no objective myocardial ischemia was identified with blood tests, electrocardiography, or cardiac catheterization, we suspected that the cause of the thoracic symptoms was sharp branching of the right coronary artery, which was compressed between the ascending aorta and the pulmonary artery. To reduce the risk of sudden death in the future, we performed reimplantation of the right coronary artery. Good imaging results were obtained, and the patient is currently undergoing outpatient follow up and has not experienced recurrence of chest symptoms. We conclude that our surgical strategy to treat anomalous aortic origin of a coronary artery may be useful in the clinic.
ABSTRACT
Anomalous aortic origin of a coronary artery from the opposite sinus (AAOCA)is one of the con-genital coronary artery malformations that might cause syncope,myocardial ischemia and sudden cardiac death (SCD), particularly in adolescents and young people.The most important inducing factor of myocardial ischemia and syncope is strenuous exercise.In recent years,more and more young athletes SCD events have been reported,and SCD related to AAOCA is now becoming the hot issue of common concern. Now,the concept,classification,clinical manifestations, diagnosis,and treatment strategies of AAOCA were introduced.
ABSTRACT
Anomalous aortic origin of a coronary artery (AAOCA) can cause sudden death, especially in young athletes. AAOCA does not have any clinical cardiovascular manifestations and sudden death is often the first manifestation ; hence, it is difficult to diagnose AAOCA before a major episode occurs. We report the case of a 58-year old woman with a right coronary artery arising from the left sinus and passing between the aorta and the pulmonary artery. Although the results of the exercise treadmill test and various other tests were normal, this patient underwent coronary artery bypass, surgery using the right internal thoracic artery to preventing sudden death. Two years after the operation, she is asymptomatic and has normal results on the exercise treadmill test.
