Constrictive pericarditis is a rare complication after cardiac surgery. It is mostly seen in adults. We report a case of constrictive pericarditis in a 3-year-old child with right ventricular dysfunction after permanent pacemaker implantation during infancy for congenital complete heart block. Suspicion of constrictive pericarditis must be kept in mind during evaluation.
