Abstract：Objective To investigate the causes and preventive measures of misdiagnosis of congenital single cor-onary artery anomaly(CAA).Methods From March 2022 to October 2023,the clinical data of 2 patients with congenital single CAA misdiagnosed as coronary heart disease(CHD)were analyzed.Results Both patients had a history of chest tightness and palpitation after repeated activities,which aggravated after exertion and improved after rest.Both patients had a history of hypertension.One patient had a history of diabetes,cerebral infarction and atrial fibrillation.Multiple electrocar-diograms and other related examinations revealed myocardial ischemic changes.Cervical vascular ultrasound showed plaque formation and dyslipidemia.However,no obvious abnormality was found in cardiac color Doppler ultrasound,and no coronary artery-related examination was performed,so they were misdiagnosed as CHD.The patient was diagnosed with congenital single CAA by relevant examinations and coronary angiography.The duration of misdiagnosis was 5 and 8 years respectively.After the diagnosis was made,the patient's symptoms were improved and the effect was obvious.Up to now,there was no ob-vious discomfort.Conclusion Congenital single CAA is a rare disease in clinical practice and often presents with clinical symptoms,which is similar to CHD.Timely coronary artery-related examinations helps to confirm the diagnosis and is not only beneficial to disease prevention and risk notification,but also beneficial to the rehabilitation of patients.
