A 51-year-old male was admitted with fever, dyspnea, and peripheral edema.His past historywas significant for hypertension, diabetes, chronic renal failure, and a bilateral carotid endarterectomy. A cardiac computed tomography scan revealed a pericardial mass (12 × 7.3 cm) which extended to compress the right ventricle (Figure 1). T1 and T2 signal intensities suggested that thiswas consistentwith a fluid-filled pericardial cyst. A coronary angiogram showed a total occlusion of the left anterior descending (LAD) artery with serial stenosis of the right coronary artery (RCA). Amedian sternotomy revealed the pericardialmass adjacent to the right atriumandventricle andextended to thepulmonaryartery (Figure2). The mass was entered, serous fluid was removed, and the cyst wall was partially excised. It was extensively adherent to the area adjacent to the RCA. An off-pump left internal mammary artery to LAD anastomosis was performed. On the fifth postoperative day, two drug-eluting stents were
