Abstract：
A stroke patient with supracristal ventricular septal defect accompanying suspected patent foramen ovale underwent transthoracic and transesophageal echocardiography with agitated saline microbubble study, a positive trans-ventricular microbubble jet after Valsalva maneuver provocation was detected, indicating instantaneous transient paradoxical right-to-left shunt at late diastole might be the etiology of embolic events. (Level of Difficulty: Intermediate.).
摘要：
1例伴有疑似卵圆孔未闭的经胸廓上室间隔缺损的卒中患者接受了经胸和经食道超声心动图和激动性盐水微泡研究，Valsalva机动刺激后检测到一个阳性的跨心室微泡喷射，指示在舒张晚期的瞬时短暂性自相矛盾的从右到左分流可能是栓塞事件的病因。（难度等级：中级。).
