E valuating the efficacy of the Dor procedure when that procedure is added to coronary artery bypass surgery was one of the 2 major objectives of the Surgical Treatment for Ischemic Heart Failure (STICH) trial, the results of which were reported in 2009.1 The Dor procedure involves removing both akinetic and dyskinetic segments of the anterior wall and reshaping the left ventricle (LV), in order to restore its original elliptical form. Here, we describe the case of a patient who, 10 years after receiving a Dacron epicardial patch as a research subject in the STICH trial, presented with purulent pericarditis from Clostridium difficile.
Case ReportIn March 2013, a 69-year-old man presented with a progressively enlarging pulsatile mass in the left side of his chest. He had no constitutional symptoms and reported no symptoms of decompensated heart failure, such as shortness of breath, dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea, or peripheral edema. Nor did he have abdominal symptoms suggestive of volume overload. Physical examination revealed a temperature of 37.3 °C, a heart rate of 70 beats/min, a blood pressure of 122/58 mmHg, and a large, pulsating mass protruding from his chest wall, surrounded by erythema. His medical comorbidities included ischemic cardiomyopathy with an LV ejection fraction recently measured at 0.15, chronic obstructive pulmonary disease with emphysema, chronic kidney disease, alcohol abuse, and tubulovillous adenoma of the transverse colon. His surgical history included (in 2003) coronary artery bypass grafting combined with the Dor procedure (including placement of a felt-and-Dacron epicardial patch), as well as a transverse colectomy (in 2012).Six months before this presentation, he had been admitted to another hospital for non-ST-segment-elevation myocardial infarction and cardiogenic shock, an admission that was complicated by C. difficile bacteremia without colitis. Two weeks of treatment with metronidazole achieved clearance of blood cultures and clinical resolution. No obvious cause for the C. difficile bacteremia was found; the evaluation included a negative computed tomographic (CT) scan of the abdomen and pelvis.
