Abstract

An elderly woman presented with unexplained, intermittent hypoxaemia unrelated to posture. Subsequent investigations revealed intermittent and variable right-to-left interatrial shunting through a patent foramen ovale in the presence of normal pulmonary arterial and intracardiac pressures, caused by right atrial compression from a horizontal, elongated ascending aorta. Surgical closure of the foramen resulted in marked clinical improvement.

摘要

一位老年女性出现原因不明的、与体位无关的间歇性低氧血症。随后的检查发现，在肺动脉和心内压力正常的情况下，存在通过卵圆孔未闭的间歇性、可变的右向左心房分流，这是由水平、细长的升主动脉压迫右心房所致。卵圆孔手术闭合后临床症状明显改善。
