A Novel Perspective on Histopathology Provides Novel Insights into Surgical Effects in Pulmonary Atresia, Ventricular Septal Defect, and Major Aortopulmonary Collateral Arteries: A Case-Series Study

Background: Never had literatures characterized the relationship between the property of major aortopulmonary collateral arteries (MAPCAs) and outcomes of selective unifocalization of pulmonary atresia with ventricular septal defects and MAPCAs. Methods: This is a case-series study. Thirteen patients were included. Angiography-based assessment was conducted to determine whether collateral arteries should be unifocalized or treated with...
