Association of Previous Cardiac Surgery With Postoperative Pneumonia in Infants Undergoing Abdominal Operations: A Cohort Study

Children with congenital heart disease (CHD) often require other, non-cardiac related surgical procedures following their initial cardiac surgery. After full or partial CHD repair, they remain at increased risk of postoperative complications. We examined the association of previous cardiac intervention (surgery or percutaneous catheterization intervention) with postoperative pneumonia in infants undergoing abdominal general surgery.
