室间隔膜部瘤及其所致的右室流出道血流动学性梗阻

ANEURYSM OF THE MEMBRANOUS VENTRICULAR SEPTUM AND ITS COMPLICATION OF RIGHT VENTRICULAR OUTFLOW HEMODYNAMIC OBSTRUCTION

室间隔膜部瘤多合并室间隔缺损。在本组１６２例经左心室造影诊断的膜部空间隔缺损中，有２８例合并室间隔膜部瘤，其中６例导致右室流出道血流动力学性梗阻。本文对室问隔膜部瘤及其所致的右室流出道血流动力学性梗阻的诊断及临床意义予以讨论。

ne hundred and sixty four cases of ventricular septal defect(VSD)were diagnosed bycine left ventriculography. Of them 162 cases were membranous VSD and 2 cases muscularVSD and 28 cases complicated by aneurysm of the membranous ventricular septum(AMS).Among AMS cases 6 had right ventricular outflow hemodyynamic obstruction. The obstruc-tion only occurred in systolic interval,but disappearred in diastolic interval. Fatigue was themain symptom of these patients.The diagnosis and clinical significance of AMS were dis-cussed.
