Forty patients with simple atrial septal defect had left ventriculograms using cineangiography and/or Elema or Sircam still films. All had open heart surgery and careful scrutiny of the mitral valve by experienced surgeons. Prolapse of the posterior cusp was diagnosed from angiography in 28 patients but was confirmed at operation in only 5. Another 5 had a different mitral valve abnormality and the remaining 18 had no clinical signs to suggest mitral valve dysfunction after operation. It is concluded that though true ballooning or prolapse of the mitral cusps may coexist with simple atrial septal defect, its presence is overdiagnosed from the appearances of left ventriculography on anteroposterior, lateral, and right anterior oblique views. Left ventriculography was equally unreliable in the exact recognition of other anatomical abnormalities of the mitral valve in secundum defect, but accurate when the mitral valve was pronounced to be structurally normal.
40例单纯房间隔缺损患者接受了心血管造影和/或Elema或Sircam静态电影摄影术进行左心室造影。所有患者均接受了心脏直视手术，经验丰富的外科医生对二尖瓣进行了仔细检查。28例患者经血管造影诊断为后叶瓣脱垂，但仅5例在手术中得到证实。另外5例有不同的二尖瓣异常，其余18例术后无临床体征提示二尖瓣功能障碍。结论是，虽然二尖瓣叶真正的膨出或脱垂可能与单纯房间隔缺损并存，但根据前后位、侧位和右前斜位左心室造影的表现，其存在被过度诊断。在继发孔缺损中，左心室造影在准确识别二尖瓣的其他解剖异常方面同样不可靠，但当二尖瓣在结构上被判定正常时则准确。
