Answer

Studies demonstrate that failure rates are proportional to the amount of pericardium removed (ie, the more pericardium removed, the less likely the procedure will fail). In effusive pericarditis, the higher failure rate associated with a pericardial window procedure or partial pericardiectomy is likely secondary to the continued fluid production from the remaining pericardium, with sealing of the remaining pericardium to the heart.
