Of 264 patients undergoing pulmonary valvotomy for pulmonary stenosis or atresia at the University of Minnesota, 23 had a right-to-left shunt preoperatively. In none was the atrial communication closed at the time of pulmonary valvotomy. At postoperative cardiac catheterization, no atrial level shunt was found in 19, indicating that effective closure of the communication had occurred. In the remaining 4, a right-to-left shunt persisted despite adequate relief of the stenosis. Each of the 4 has undergone subsequent closure of the atrial septal communication without difficulty.
在明尼苏达大学接受肺动脉瓣切开术治疗肺动脉狭窄或闭锁的264例患者中，23例术前存在右向左分流。在进行肺动脉瓣切开术时，无一例患者的心房交通被闭合。术后心导管检查时，19例未发现心房水平分流，这表明交通已有效闭合。其余4例患者，尽管狭窄得到了充分缓解，但右向左分流仍然存在。这4例患者随后均顺利进行了房间隔交通闭合术。
