The Functional Intraoperative Pulmonary Blood Flow Study Is a More Sensitive Predictor Than Preoperative Anatomy for Right Ventricular Pressure and Physiologic Tolerance of Ventricular Septal Defect Closure After Complete Unifocalization in Patients With Pulmonary Atresia, Ventricular Septal Defect, and Major Aortopulmonary Collaterals

Abstract

The intraoperative pulmonary flow study predicted postoperative physiology significantly better than did standard anatomic measures. Conventional measures should be used with caution when determining the possibility for complete repair.
