Postoperative pathology of congenital heart disease

The evaluation of congenitally malformed hearts that have been subjected to operative and nonoperative interventions includes not only a categorization of the underlying anomalies and various procedures but also an assessment of interventional complications, postprocedural changes in chamber, valvular, and vascular sizes, presence of ischemia or fibrosis, presence of cardiac or extracardiac infections, and evidence of regression or progression of hypertensive pulmonary vascular disease. Input from clinicians or surgeons may be helpful, but biases should be avoided. Referral of cardiopulmonary specimens to experienced pathologists may also be considered.
