OBJECTIVES The aim of this study was to define age-stratified, procedure-specific benchmark radiation dose levels during interventional catheterization for congenital heart disease. BACKGROUND There is a paucity of published literature with regard to radiation dose levels during catheterization for congenital heart disease. Obtaining benchmark radiation(More)
OBJECTIVES This study sought to develop a method to adjust for case mix complexity in catheterization for congenital heart disease to allow equitable comparisons of adverse event (AE) rates. BACKGROUND The C3PO (Congenital Cardiac Catheterization Project on Outcomes) has been prospectively collecting data using a Web-based data entry tool on all(More)
BACKGROUND Long-term outcome of patients with pulmonary valvar atresia and intact ventricular septum with right-ventricle-dependent coronary circulation (PA/IVS-RVDCC) managed by staged palliation directed toward Fontan circulation is unknown, but should serve as a basis for comparison with management protocols that include initial systemic-to-pulmonary(More)
BACKGROUND Significant morbidities, including angina, symptomatic heart failure, and myocardial infarction, have been reported after coronary artery fistula (CAF) closure; however, predictors that may be associated with adverse outcomes have not been established. The goal of this investigation is to describe the long-term outcomes witnessed in patients with(More)
BACKGROUND Readmission after operations for congenital heart conditions has significant implications for patient care. Readmission rates vary between 8.7% and 15%. The aim of this study was to determine the incidence, causes, and risk factors associated with readmission. METHODS 811 consecutive patients undergoing operations for congenital heart(More)

Pediatric and Congenital Interventional Cardiology is the practice of catheter-based techniques that improve cardiac physiology and circulation through the treatment of heart disease in children and adults with congenital or acquired heart defects. Over the last decade, and since last published training guidelines for pediatric cardiac catheterization and(More)
Continued advancements in congenital cardiac catheterization and interventions have resulted in increased patient and procedural complexity. Anticipation of life-threatening events and required rescue measures is a critical component to preprocedural preparation. We sought to determine the incidence and nature of life-threatening adverse events in(More)
BACKGROUND Shear stress-induced platelet dysfunction (PD) is prevalent among adults with aortic stenosis. Our aim was to determine whether abnormal platelet function was associated with specific congenital cardiac lesions in children. METHODS The charts of 407 children who had undergone cardiopulmonary bypass and had preoperative platelet function(More)
