UNLABELLED
We report a rare case with a right-to-left shunt across patent foramen ovale induced by increased blood volume in the right heart structures and severe tricuspid regurgitation which was attributed to a left-to-right shunt via coronary cameral fistulas, resulting in systemic hypoxia without pulmonary hypertension.
LEARNING OBJECTIVES
Right-to-left and left-to-right shunts across patent foramen ovale and coronary cameral fistulas can coexist, potentially worsened by another shunt and vice versa.
未标注
我们报告了一例罕见病例，右心结构血容量增加和严重三尖瓣反流导致经卵圆孔未闭出现右向左分流，这归因于通过冠状窦瘘的左向右分流，导致全身缺氧但无肺动脉高压。
学习目标
经卵圆孔未闭和冠状窦瘘的右向左和左向右分流可同时存在，可能因另一种分流而加重，反之亦然。
