A 57-year-old man experienced sudden onset of pleuritic chest pain and respiratory distress 10 days after undergoing four-vessel coronary artery bypass grafting (CABG). The surgery was performed after cardiac catheterization had shown right coronary artery dominance and the presence of lesions occluding 40% of the mid right coronary artery, 20% of the left main coronary artery, and 99% of the lower left anterior descending artery and its first diagonal branch. The patient had initially presented with acute dyspnea following an episode of crushing, nonradiating pain in the left chest and was diagnosed as having a non-Q-wave myocardial infarction after cardiac enzyme testing. His hospital course before and immediately after CABG was uneventful. The first sign of difficulty was detected one week after surgery, on day 17. An echocardiogram showed a small pericardial effusion, moderate to severe concentric thickening of the left ventricle, a left ventricular ejection fraction of 0.60 (normal, 0.67 ± 0.08), normal valves, and normal segmental wall motion. The pleural chest pains began two days later, on day 19.
