超声心动图评价动脉导管未闭封堵术后心脏结构和心功能变化
The changes of cardia morphology and function after transcatheter closure of patent ductus arteriosus by transthoracic echocardiography
摘要
Abstract
Objective To investigate the ultrasonic Heartbeat map in the evaluation of patent ductus arteriosus (PDA) changes in patients after transcatheter closure of cardiac structure, heart function and hemodynamics. Method Transthoracic echocardiography Beckoning graph (TTE) examination conifrmed the diagnosis of 84 cases of PDA patients, male 22 cases, female 62 cases, age 1~57 years, mean age (15.1±13.6) years old. PDA diameter of 1.7 ~ 18.7 mm, average diameter was (6.3±3.4) mm. All patients were all successful closure. In the preoperative, postoperative 48 hours, after 1 month, 3 months after the operation, after 6 months and 1 year after operation, determination of cardiac structure, cardiac function and haemodynamics index using TTE. Result 48 hours after operation and later left atrial diameter, left ventricular diameter than the preoperative patients, pulmonary artery diameter, mitral lfow velocity, aortic blood lfow velocity, pulmonary artery systolic pressure and left ventricular ejection fraction decreased, the difference was signiifcant (P<0.05);after 1 month and after patients 48 hours after surgery in patients with left ventricular diameter decreased, the difference was signiifcant (P<0.05). Conclusion Transcatheter closure of PDA not only can effectively cure congenital anatomic deformity, and can quickly correct the abnormal hemodynamics in the early, improve left ventricular geometry and heart function.关键词
