Abstract

Heart transplantation (HTx) in children with a univentricular physiology is a challenge. In this study, we aimed to investigate the early and late survival as well as the causes of death of HTx recipients at different stages of univentricular palliation. Between January 1987 and September 2015, 40 orthotropic cardiac transplants were performed in 38 children with univentricular hearts at our institution. Outcomes were reviewed using medical records and transplant databases. For the purposes of this analysis, patients were divided into 3 subgroups according to their stage of palliation: Stage 1 (n = 10, 26%), Stage 2 (n = 5, 13%) and Fontan (n = 23, 61%). The median age at HTx was 15.2 years (range 0-38). The median follow-up time after transplantation was 8.7 years (range 0-25.4). Indications for transplant were ventricular dysfunction in 25 (66%) patients, protein losing enteropathy in 10 patients transplanted in Fontan (26%) and refractory arrhythmias in 3 (8%) patients with an atriopulmonary connection. Total mortality was 42% (4.84/100 patient-years), and total early mortality was 21%. Overall survival at 1, 10 and 20 years was 73% (95% confidence interval 56-84%), 58% (95% confidence interval 40-72%) and 49% (95% confidenc...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
