Not draining effusion was associated with higher CP risk after CABG; leaves open whether drainage prevents constrictive pericarditis.
Does pericardial drainage prevent the development of constrictive pericarditis in patients with postoperative pericardial effusion after CABG?
Pericardial drainage for significant effusion after CABG is important for preventing subsequent constrictive pericarditis, especially in patients treated with warfarin or with normal left ventricular function.
Matsuyama et al. (2001) studied this question.
