ReviewOptimizing response of the neonate and infant to cardiopulmonary bypass.
Despite the ability to surgically correct complex defects in neonates and infants, limitations in outcome are sometimes encountered in relation to exposure to cardiopulmonary bypass (CPB). The deleterious effects of CPB in neonates are often pronounced because of their immature tissue/organ function and the disparity between the CPB circuit size and the patient. A variety of techniques that have been developed to prevent or lessen tissue edema, including miniaturization of the circuit and oxygenator, prime additives (eg, albumin, steroids), biocompatible circuitry, and variations in perfusion strategies, are discussed as are post-CPB strategies such as modified ultrafiltration, which removes inflammatory mediator-rich fluid from the patient and bypass circuit. With optimization of the response of the infant to our systems used during repair of their cardiac lesion, we will see significant improvement in surgical outcomes.

Review Comparative StudyEthical issues concerning cardiac surgery in patients with syndromic abnormalities.
Advances in surgical techniques, cardiac anesthesia, and pre- and postoperative care have made the surgical treatment of complex congenital cardiac disease available to an ever-increasing number of children, including those with a wide range of extracardiac anomalies. Over the past few decades cardiac surgery in infants and children with syndrome-associated physical and mental conditions has undergone a remarkable change, with previously held norms abandoned for new standards. The social, ethical, and clinical appropriateness of these changes has been the focus of much attention. In this article, we provide a brief history of cardiac surgery in children with congenital syndromes, discuss some groundbreaking cases such as that of "Baby Doe," and present some rules of thumb for the pediatric cardiac surgeon and cardiologist to use when caring for children with congenital syndromes.

Arrhythmia surgery in association with complex congenital heart repairs excluding patients with fontan conversion.
Surgical arrhythmia therapy may be performed for patients failing the catheter ablation approach or incorporated into repair of complex congenital heart disease. Variations in atrial and ventricular anatomy that may limit the catheter approach can be directly addressed surgically assuring lesion depth and continuity of anatomic lines of block. Between July 1992 and August 2002, we performed arrhythmia surgery on 34 patients for refractory atrial (n = 29) or ventricular (n = 5) arrhythmias. ⋯ Ventricular tachycardia was inducible postoperatively in two of three patients with ventricular arrhythmias and congenital heart disease. Patient size or anatomic complexity should not be limiting factors in the combined surgical arrhythmia approach. Because older patients undergoing surgical revision of prior surgical repairs of congenital heart disease are at increased risk for the later development of atrial arrhythmias, incorporation of arrhythmia therapy into any planned surgical revision should be routinely considered.

Review Historical ArticleSoftware development, nomenclature schemes, and mapping strategies for an international pediatric cardiac surgery database system.
The field of congenital heart surgery has the opportunity to create the first comprehensive international database for a medical subspecialty. An understanding of the demographics of congenital heart disease and the rapid growth of computer technology leads to the realization that creating a comprehensive international database for pediatric cardiac surgery represents an important and achievable goal. The evolution of computer-based data analysis creates an opportunity to develop software to manage an international congenital heart surgery database and eventually become an electronic medical record. ⋯ An international committee will map the two systems. The ideal coding system will permit a diagnosis or procedure to be coded only one time with mapping allowing this code to be used for patient care, billing, practice management, teaching, research, and reporting to governmental agencies. The benefits of international data gathering and sharing are global, with the long-term goal of the continued upgrade in the quality of congenital heart surgery worldwide.

ReviewPostoperative management in patients with complex congenital heart disease.
Life-threatening problems occur in the neonate and infant after cardiac surgery because of the interplay of diminished cardiac output (CO), increased metabolic demand, inflammatory responses to cardiopulmonary bypass, and maladaptive responses to stress. Therefore, the postoperative management of patients with complex congenital heart defects is directed at optimization of oxygen delivery to maintain end-organ function and promote wound healing. Traditionally, assessment of circulation in the postoperative congenital heart patient has depended on indirect assessment of CO using parameters such as blood pressure, pulses, capillary refill, and urine output. ⋯ A uniform approach to airway maintenance, vascular access, and drug infusions, all universal concerns during the perioperative period, minimizes the potential for these predictable and necessary interventions to result in morbidity or mortality. Management of the postoperative single ventricle patient targets stabilization of the systemic vascular resistance through the use of vasodilators to improve systemic perfusion and simplify ventilator management. Management of any individual patient should be driven by objective analysis of available data and must include efforts to re-evaluate the treatment plan as well as to identify unanticipated problems.
