Virtual modeling of cardiothoracic surgery is a new paradigm that allows for systematic exploration of various operative strategies and uses engineering principles to predict the optimal patient-specific plan. This study investigates the predictive accuracy of such methods for the surgical palliation of single ventricle heart defects. Computational fluid dynamics (CFD)-based surgical planning was used to model the Fontan procedure for four patients prior to surgery. The objective for each was to identify the operative strategy that best distributed hepatic blood flow to the pulmonary arteries...

The medical records of all patients born between 1 September, 2000, and 31 August, 2002, and undergoing the first stage of Norwood reconstruction, were retrospectively reviewed for details of the perioperative course. We found 99 consecutive patients who met the criterions for inclusion. Hospital mortality for the entire cohort was 15.2%, but was 7.3%, with 4 of 55 dying, in the setting of a "standard" risk profile, as opposed to 25.0% for those with a "high" risk profile, 11 of 44 patients dying in this group...

This review discusses the historical aspects, current state of the art, and potential future advances in the areas of nomenclature and databases for congenital heart disease. Five areas will be reviewed: (1) common language = nomenclature, (2) mechanism of data collection (database or registry) with an established uniform core data set, (3) mechanism of evaluating case complexity, (4) mechanism to ensure and verify data completeness and accuracy, and (5) collaboration between medical subspecialties. During the 1990s, both the Society of Thoracic Surgeons (STS) and the European Association for Cardiothoracic Surgery (EACTS) created congenital heart surgery outcomes databases...

OBJECTIVE: To explore whether prenatal diagnosis of congenital heart disease is associated with lower levels of parental distress and greater satisfaction with decisions about cardiothoracic surgery when compared to postnatal diagnosis. METHODOLOGY: A combined quantitative-qualitative design was used. Participants included the parents of 31 neonates (30 mothers and 22 fathers) admitted to the cardiac intensive care unit between 1 November 2001 and 1 May 2002 for repair of congenital cardiac malformations...

INTRODUCTION: Persistent patent ductus arteriosus (PDA) often produces hemodynamic and respiratory derangement necessitating use of inotropic drugs and escalating ventilatory support in premature infants. When medical therapy fails, surgical ligation is indicated. Because of the risks of transferring unstable neonates to the operating room, ductal ligation is routinely performed at the neonatal intensive care unit (NICU) bedside. Some patients, however, require transfer from hospitals without pediatric cardiac surgical teams...
