Untreated infectious aneurysms of native coronary artery and aortocoronary bypass grafts are associated with high mortality. Early diagnosis proves difficult given nonspecific presenting symptoms; however, once recognized, early intervention is essential to mitigate complications such as myocardial ischemia or pericardial tamponade. In this case report, we describe the successful surgical management of a patient who presented 2 months after diagnosis of Staphylococcus aureus bacteremia with cardiogenic shock from rupture of an infected saphenous vein graft aneurysm resulting in pericardial tamponade.
