A 58-year-old man underwent an elective coronary bypass graft for severe four-vessel stenosis. Cardiogenic shock developed just after coronary bypass grafting with a left internal mammary artery (LIMA) to left anterior descending (LAD) artery and superficial venous graft to 1st and 2nd obtuse marginal (OM1/OM2) arteries the posterior descending artery (PDA) was too small to graft. Despite significant inotropes and an intra-aortic balloon pump, the patient deteriorated in intensive care unit with cardiogenic shock and ventricular arrhythmia. Urgent coronary angiography revealed a rupture or torn LIMA graft with extravasation of contrast into the left pleural cavity. There was no distal LIMA to LAD flow probably due to graft thrombosis. Revascularisation was performed on the severe ostial native LAD stenosis with a drug eluting stent. The rupture graft was then stented with a polytetrafluoroethylene-covered stent, which stopped the bleeding, and latter, led to total graft thrombosis. The patient improved significantly and supportive inotropes could be weaned down. At 11 month follow-up, the patient had mild left ventricular dysfunction, widely patent ostial LAD stent and thrombosed LIMA graft. © 2011 Wiley Periodicals, Inc.
