Transient tricuspid valve insufficiency following acute inferior myocardial infarction

Tricuspid valve insufficiency following acute myocardial infarction is uncommon. It may be explained by right ventricular papillary muscle dysfunction. We report the case of a patient with acute tricuspid valve incompetence during the acute phase of a left ventricular inferior infarction with right ventricular myocardial involvement. The treatment during the acute phase consisted of volume loading and positive inotropic agents. Seven days later the clinical signs of tricuspid valve insufficiency and concomitant right heart failure had disappeared. To our knowledge transient tricuspid valve insufficiency following acute inferior myocardial infarction has not been reported previously.
