Abstract:
Objective Explore the influence of different surgical methods on right coronary artery opening after congeni-tal supravalvular aortic stenosis correction surgery, to avoid right coronary artery obstruction caused by surgery.Methods A retrospective analysis was made on the surgical methods and results of continuous records of 91 supravalvular aortic stenosis sur-gery cases operated from 2008 to 2015, while analyzing the cause of early death, early reoperation, and ECMO assisted.Re-sults 4 cases of perioperative death,6 cases of ECMO assisted,8 cases of reoperation,all above are concerned with early ma-lignant arrhythmia.The surviving cases were followed up for 15 months,no death cases during the followed-up.Conclusion Different surgical methods have different influences on right coronary artery, related to the operation of right coronary incision. If the patch is oversize,it will cause obstruction of right coronary artery opening and cause malignant arrhythmia,however,un-dersized patch can not relieve aortic stenosis.So different surgical methods should be used according to different age and weight of patients.
