Refractory hypoxemia in inferior myocardial infarction from right-to-left shunting through a patent foramen ovale: a case report and review of the literature.
Right ventricular (RV) infarction is a well-recognized complication of some acute inferior myocardial infarctions. Recently, there have been numerous case reports of RV infarctions complicated by severe refractory hypoxemia secondary to right-to-left shunting through a patent foramen ovale. An additional case missed by transthoracic echocardiography and cardiac catheterization is reported and the English literature on the subject is reviewed.
