Myocardial Abscess Due to Klebsiella pneumoniae Complicating Acute Infarction

Ventricular Rupture at the Site of a Septic Myocardial Abscess After Acute Myocardial Infarction

“…6 The most common causative organisms are Staphylococcus and Streptococcal species, although a variety of other organisms have also been described. 2 , 7 Contributing to the rarity of this case is abscess formation by an anaerobe. Although anaerobic myocardial abscesses are exceedingly rare, it is hypothesized these organisms are supported by the relatively hypoxic postinfarction environment.…”

“…The identification of myocardial abscesses post-AMI is challenging and rarely diagnosed antemortem. 5 , 6 , 7 , 8 They are characteristically silent and often obscured by the superimposed septic process and sequalae of the presenting ACS. 8 Useful features to raise clinical suspicion include bacteremia, persistent fever despite appropriate antimicrobials, and progressive hemodynamic deterioration.…”

A rare case of Klebsiella pneumoniae myocardial abscess

“…1,2 They usually occur in the setting of IE with Gram-positive cocci 1,2 and some-times in infarcted myocardium when circulating microorganisms get seeded in the region. 4 Our patient, who presented with chest pain and electrocardiogram changes consistent with acute coronary syndrome (ACS), was incidentally found to have K pneumoniae myocardial abscess during CABG.…”

“…Maslow et al 4 have reported the only other case of myocardial abscess due to K pneumoniae. Their patient had K pneumoniae urosepsis associated with acute myocardial infarction, resulting in myocardial abscess and papillary muscle rupture.…”
