The systemic right ventricle in congenitally corrected transposition of the great arteries is different from the right ventricle in dextro-transposition after atrial switch: a cardiac magnetic resonance study.
Patients with a congenitally corrected transposition of the great arteries show an increasing incidence of cardiac failure with age. In other systemic right ventricles, such as in dextro-transposition after atrial switch, excessive hypertrophy is a potential risk factor for impaired systolic function. In this trial, we sought to compare systemic function and volumes between patients with congenitally corrected transposition and those with dextro-transposition after atrial switch by using cardiac magnetic resonance imaging. ⋯ Although patients with congenitally corrected transposition had a longer pressure load of the systemic right ventricle, ventricular function was better compared with that in patients with dextro-transposition after atrial switch. The results suggest that the systemic ventricles might have partly different physiologies. One difference could be the post-operative situation after atrial switch, which results in impaired atrial contribution to ventricular filling.

Extended survival and re-hospitalisation among paediatric patients requiring extracorporeal membrane oxygenation for primary cardiac dysfunction.
Although survival to hospital discharge among children requiring extracorporeal membrane oxygenation support for medical and surgical cardio-circulatory failure has been reported in international registries, extended survival and re-hospitalisation rates have not been well described in the literature. ⋯ Extended survival rates for paediatric hospital survivors of cardiac extracorporeal membrane oxygenation support for medical and post-surgical indications are encouraging. However, re-hospitalisation within the first year following hospital discharge is common, and many patients require further cardiac surgery. Although re-admission hospital mortality is low, longer-term follow-up of quality-of-life indicators is required

Case ReportsTreatment of haemoptysis in pulmonary atresia with tranexamic acid.
We report the case of a young woman with continuing haemoptysis, pulmonary atresia, previous shunt surgery, and pulmonary hypertension. She was not suitable for further surgery or for therapeutic embolisation of bronchial vessels. Treatment with tranexamic acid resolved the haemoptysis.

Case ReportsPericardial effusion in an infant with severe respiratory syncytial virus bronchiolitis.
Respiratory syncytial virus is the most common pathogen causing lower respiratory tract infection in infants. Respiratory syncytial virus infection is also associated with a number of extrapulmonary manifestations, including the cardiac system. Pericardial effusion, however, is a very rare occurrence with respiratory syncytial virus infection. We report a very young infant with respiratory syncytial virus bronchiolitis whose clinical course was associated with pericardial effusion, treated conservatively.
