ABSTRACT
Objective Analyze the surgical and follow-up outcomes of congenital coronary artery fistula(CAF) in children and to discuss the treatment methods.Methods The clinical data were analyzed retrospectively in 22 patients who were diagnosed as congenital CAF and received surgical treatment between July 2008 and January 2017 in Guangzhou Women and Children's Medical Center.There were 14 boys and 8 girls.The median age was 17 months ranging from 14 days to 12 years old.The median weight was 8.8 kilograms ranging from 3.0 to 31.0 kilograms.Results Two patients had shortness of breath.Three had growth retardation with recurrent respiratory infection or tachypnea.The remaining 17 patients were asymptomatic.Twenty had heart murmurs.Fistulas originated from right coronary artery accounted for 11 patients,with 10 from left coronary artery,1 from both right and left coronary arteries.Fistulas drained into coronary sinus in 1 patient,right atrium in 6 patients,right ventricular in 13 patients and left ventricular in 2 patients.Single fistula occurred in 20 patients and multiple fistulas in 2 patients.The coronary arteries were obviously dilated in all patients with diameter from 4.0 to 12.0 millimeters.There were 8 cases with aneurysmal dilation of coronary arteries.Two patients underwent fistula ligation without cardiopulmonary bypass(CPB).The remaining 20 cases received fistula correction with beating heart CPB.Direct suture was used in 3 patients for closure of fistula inlet and 11 children for outlet.Both inlet and outlet were closed in 6 patients,and in 2 of them autologous pericardial patch was used for outlet.Other associated intra-cardiac anomalies in 7 children were corrected during the operation.The aneurysmal coronary arteries remained original shape without any intervention during the operation.The mean hospital delay was(12.3±3.2) days.Two patients appeared decreased heart function within 3 days after the operation,and recovered in return visit one month later.Another 2 patients showed a residual shunt with size of 1 to 2 millimeters through the fistula without further intervention after the surgical closure.During the perioperative period and the follow-up period(3 months to 8 years),all 22 patients were asymptomatically alive without regular anticoagulation management.Transthoracic echocardiography showed normal cardiac function.Compared with preoperative status,the diameter of dilated coronary arteries was reduced over 6 months follow up after the operation.There were no formation of thrombus in the coronary arteries.Electrocardiography showed no ST-T changes or arrhythmia or myocardial ischemia.Conclusion Clinical symptoms can be appeared in children with congenital CAF due to large shunt.Surgical correction is an effective method for the management of single CAF or CAF with coexisted intra-cardiac anomalies.The outcome was well.
