Abstract

Seven patients (four adults, three children) with discrete subaortic membranous stenosis underwent balloon dilatation using a single or double balloon technique with reduction in systolic gradient across the membrane from 100.42 +/- 19.23 to 29.14 +/- 12.54 mmHg (P less than 0.001). Echocardiography demonstrated thin membranes in all the patients and postprocedure torn fragments could be visualized. The excellent hemodynamic benefits are sustained during 4-24 months follow-up. The results indicate that transluminal balloon dilatation can be a safe and effective treatment for thin subaortic membrane.

摘要

7例（4例成人，3例儿童）患有孤立性主动脉瓣下膜性狭窄的患者接受了单球囊或双球囊技术的球囊扩张术，跨膜收缩期压力阶差从100.42±19.23 mmHg降至29.14±12.54 mmHg（P<0.001）。超声心动图显示所有患者的瓣膜均较薄，术后可见撕裂碎片。在4至24个月的随访期间，血流动力学改善效果良好。结果表明，经皮腔内球囊扩张术对于薄型主动脉瓣下隔膜是一种安全有效的治疗方法。
