ABSTRACT
Objective To observe the clinical characteristics and prognosis in children with high take -off coronary artery.Methods The clinical characteristics,laboratory examinations and prognosis were retrospectively ana-lyzed in 49 children with high take -off coronary artery who had been admitted to Beijing Children′s Hospital Affiliated to Capital Medical University from April 2009 to December 201 2.Results Among 49 medical records of children with high take -off coronary artery,34 cases were male and 1 5 cases were female,with a mean age of (9.28 ±4.42)years old,and the youngest patient was 1 3 months old,and the oldest patient was 1 7 years and 2 months old.The 64 -section multidetector CT angiography of all patients showed one or both coronary arteries originated from 1 .0 cm higher than the junction area of sinus and aorta,including 38 high take -off of the left coronary artery,7 high take -off of the right coronary artery and 4 high take -off of both coronary arteries.The chief complaints of the patients included chest pain (22 cases,44.90%),chest tightness(1 3 cases,26.53%),declining of exercise tolerance(7 cases,1 4.29%),fatigue (5 cases,1 0.20%),palpitation(3 cases,6.21 %),syncope(1 case,2.04%).Electrocardiogram(ECG)of those pa-tients showed ST -T changes,atrioventricular block,sinus tachycardia,pathological Q -wave,proiosystole and bundle branch block.Ultrasonic cardiogram(UCG)indicated 1 4 patients with the enlarged left ventricle,including 2 patients with ejection fraction lower than 60%.After 1 0 days hospitalization,the anesis of chest pain and chest tightness were significantly different statistically(P <0.05),but there was no significant difference in ECG and UCG.Thirty -nine out of 49 children were followed for 1 year.After 3 months,6 patients with ST -T problem showed normal ST -T segment. After 6 months,1 0 patients with ST -T problem showed normal ST -T segment.After 1 year,1 7 patients with ST -T problem showed normal ST -T segment.Conclusions High take -off coronary artery is a rare malformation of the coronary artery,which can cause myocardial ischemic,leading to multiple clinical manifestations and may result in ECG changes and the left ventricle enlargement.High take -off coronary artery can be confused with myocarditis and myocar-dial lesion clinically.Patients receiving systemic treatment may have their symptoms released,but ECG and UCG may not relieve in a short term.Patients with high take -off coronary artery need long -term observation.
