对32例接受心导管术和/或手术证实卵圆孔未闭(PFO)的患者进行了研究。用经胸超声心动图(TTE)和经食道超声心动图(TEE)检查正常呼吸和Valsalva动作时的AH。14例患者在正常呼吸时和20例患者在Valsalva动作时，对比TEE显示了心房水平从右向左的分流。相比之下，对比TTE只在正常呼吸时的8名患者和瓦尔萨尔瓦动作时的12名患者中发现了这种分流。与之对照，所有孔均通畅，TTE亦可见。除1例(19/20)患者外，其余患者均可在心导管术和/或手术中确诊。以心导管术和/或手术作为金标准，对比TEE似乎更敏感(100%比63%，p
A series of 32 patients undergoing cardiac catheterization and/or operation to document the presence of patent foramen ovale (PFO) were studied. AH were examined by contrast transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) during normal breathing and the Valsalva maneuver. A right-to-left shunt at the atrial level was visualized by contrast TEE in 14 patients during normal breathing and in 20 patients during the Valsalva maneuver. In comparison, contrast TTE revealed this shunt in only eight patients during normal breathing and in 12 patients during the Valsalva maneuver. All of the foramina proved to be patent by contrast TTE were also found by contrast TEE. All but one (19 of 20) patients, shown to have PFO by contrast TEE, could be confirmed at cardiac catheterization and/or operation. Using cardiac catheterization and/or operation as a gold standard, contrast TEE appears to be a more sensitive (100 percent vs 63 percent, p
