A new method for the localization of atrial septal puncture was reported, which is the key technique for percutaneous balloon mitral valvuloplasty. When the exploratory electrode was laid against the fossa ovalis floor (FOF), the atrial septal electrocardiogram registered only a slight or no injury curve; when the exploratory electrode pressed on any other area of the atrial septum or atrial walls, a bizarre monophasic injury curve was elicited in the atrial septal electrocardiogram. Based on different patterns of the atrial septal electrocardiogram between the muscular atrial septum and FOF, the sites of atrial septal puncture were successfully localized by using a Brockenbrough needle as an exploratory electrode in all of the 10 cases without any complication. By using this technique, no cardioangiography is needed to show the outline of the left atrium and also the bilateral projection catheterization bed. So this method is convenient, practical and precise.
报道了一种房间隔穿刺定位的新方法，这是经皮球囊二尖瓣成形术的关键技术。当探测电极贴靠卵圆窝底部（FOF）时，房间隔心电图记录到的仅为轻微损伤曲线或无损伤曲线；当探测电极按压在房间隔或心房壁的任何其他区域时，房间隔心电图会引出奇异的单相损伤曲线。基于肌性房间隔和FOF之间房间隔心电图的不同模式，在所有10例病例中均成功地使用Brockenbrough针作为探测电极对房间隔穿刺部位进行了定位，且无任何并发症。通过使用该技术，无需心脏血管造影来显示左心房轮廓以及双侧投影导管床。因此，该方法方便、实用且精确。
