Comparative StudyPulmonary transplantation for cystic fibrosis: pre-transplant recipient characteristics in patients dying of peri-operative sepsis.
Pulmonary transplantation has emerged as a successful treatment for end-stage cystic fibrosis. Despite the chronic bronchial sepsis and often multi-resistant organisms seen in this group of recipients, death due to post-operative sepsis is relatively scarce. Identifying potential recipient risk factors for poor outcome may further improve the utilization of a scarce donor pool. ⋯ Pre-operative B cepacia complex infection, leukocytosis and pyrexia, but not CRP, weight, diabetes or lung function, were found to be associated with poorer post-transplant outcome. The most clinically relevant of these to the subsequent risk of post-operative death from sepsis appear to be B cepacia infection and pyrexia.

Comparative StudyPediatric arteriovenous extracorporeal membrane oxygenation (ECMO) as a bridge to cardiac transplantation.
Since 1990, extracorporeal membrane oxygenation (ECMO) has been used as a bridge to cardiac transplantation in 47 patients. ⋯ Patients with cardiomyopathy has a better prognosis than did those with CHD when using ECMO as a bridge to transplantation or survival. Complications are significant and increase with the duration of support. Extracorporeal membrane oxygenation for salvage and subsequent transplantation in this high-risk group of patients requires critical review. Alternative support options must be developed in the pediatric population that will allow improved outcomes, comparable with outcomes achieved in the adult population.

Multicenter StudyMechanical Circulatory Support device database of the International Society for Heart and Lung Transplantation: first annual report--2003.
Over the last 2 decades, mechanical circulatory support devices have been developed with the goal of supporting patients with advanced heart failure as a bridge to cardiac transplantation, a bridge to recovery, and an alternative to transplantation (also called chronic or destination therapy). The current generation of devices provides a differentiated spectrum of circulatory support. The major limitations of mechanical circulatory support devices are infection, coagulopathies and device dysfunction. The Scientific Council on Mechanical Circulatory Support of the International Society for Heart and Lung Transplantation has established an international database to generate critical data to advance knowledge about the effectiveness of mechanical circulatory support device therapy for one of the most difficult and costly contemporary medical problems, the malignant syndrome of advanced heart failure.

Comparative StudyReduction of tricuspid annular doppler tissue velocities in pediatric heart transplant patients.
Orthotopic heart transplantation is a life-saving therapy for children with end-stage heart disease. However, 50% of these transplanted children die or require re-transplantation 12 years later. Progressive deterioration of cardiac function is a common feature of long-term survivors; however, quantitative evaluation of the state of the right ventricle has been lacking. Tissue Doppler imaging (TDI) has been used to measure alterations in right ventricular (RV) function in other illnesses. The purpose of this study was to quantitate abnormalities in tricuspid annular systolic and diastolic velocities as an indicator of RV dysfunction, and to evaluate if time since transplantation and the presence of tricuspid regurgitation are associated with quantitative changes in tricuspid annular velocities in pediatric heart transplant recipients. ⋯ TDI demonstrated that tricuspid annular systolic and early diastolic velocities were abnormal in children after transplantation and became significantly more abnormal with prolonged time after transplantation. These alterations were not dependent on the presence of severe tricuspid regurgitation but appeared to be exacerbated by its presence. Evidence of diastolic left ventricular dysfunction was not detected before 5 years after transplantation in this unselected group. A prospective study may be required to define the evolution and progression of right and left ventricular dysfunction in children after heart transplantation.
