Refractory hypoxemia in inferior myocardial infarction from right‐to‐left shunting through a patent foramen ovale: A case report and review of the literature

Abstract

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. Copyright © 1994 Wiley Periodicals, Inc.
