肺动脉环缩术治疗小儿心力衰竭二例

Efficacy of Pulmonary Artery Banding in Pediatric Heart Failure Patients:Two Cases Report

本文报道2例于2021年12月至2022年1月期间在中国医学科学院阜外医院接受肺动脉环缩术治疗的小儿心力衰竭病例。1例患儿8个月大,术前超声心动图及心脏磁共振成像提示左心室心肌致密化不全、左心功能不全、室间隔缺损、房间隔缺损。另1例患儿4个月大,超声心动图考虑左心室心肌致密化不全、左心功能不全、主动脉弓缩窄。经肺动脉环缩术治疗后,两例患儿左心功能及形态均显著改善,未发生严重手术相关并发症。肺动脉环缩术在小儿心力衰竭治疗的个例经验中表现出比药物治疗更满意的疗效和安全性,尤其对于药物无法控制的小儿心力衰竭,具有一定的推广价值,但仍需更多临床数据支持。

Two pediatric heart failure patients were treated with pulmonary artery banding(PAB)at Fuwai Hospital,from December 2021 to January 2022.In the first case,an 8-month-old patient presented with left ventricular non-compaction cardiomyopathy(LVNC),left ventricular systolic dysfunction,ventricular septal defect,and atrial septal defect.The second case was a 4-month-old patient with LVNC,left ventricular systolic dysfunction,and coarctation of the aorta.After PAB,the left ventricular function and shape of both patients were significantly improved,without serious surgery-related complications.In these individual cases of pediatric heart failure,pulmonary artery banding exhibited a more satisfactory efficacy and safety compared to pharmacological treatment,especially for those with unsatisfactory medication results.Future clinical data are needed to promote the rational and broader application of this therapeutic option for indicated patients.
