Evaluation of left ventricular torsion in children with hypertrophic cardiomyopathy.
To evaluate the role of torsion in hypertrophic cardiomyopathy in children. ⋯ In contrast to an increased counterclockwise apical rotation in concentric hypertrophy, hypertrophic cardiomyopathy is characterised by predominantly enhanced systolic basal clockwise rotation. Diastolic untwisting is delayed in both groups. Torsion may be an interesting marker to guide patients with hypertrophic cardiomyopathy.

The management of patients with Fontan physiology who undergo scoliosis surgery is difficult. The purpose of this article was to describe our experience in the management of patients with Fontan circulation undergoing spinal surgery for correction of scoliosis. ⋯ Spinal surgery in patients with Fontan circulation is a high-risk operation. These patients must be managed by a specialised team.

Observational StudyExtubation failure in infants with shunt-dependent pulmonary blood flow and univentricular physiology.
The objective of the study was to identify incidence, aetiology, and outcomes of extubation failure in infants with shunt-dependent pulmonary blood flow at a single tertiary care, academic children's hospital. The second objective of this study was to determine the haemodynamic effects of transition of positive pressure ventilation to spontaneous breathing in infants with extubation failure. ⋯ Extubation failure in infants with shunt-dependent pulmonary blood flow and univentricular physiology is high and aetiology is diverse. Cardiopulmonary effects of removal of positive pressure ventilation are more pronounced in children with extubation failure and include escalation in the need for oxygen requirement and increase in mean arterial blood pressure. The majority of extubation failures in this select patient population occurs in the first 24 hours. Extubation failure in these patients is not associated with increased hospital length of stay or mortality.

Assessment of atrial electromechanical delay in children with acute rheumatic fever.
There may be an increase in the risk of atrial arrhythmia due to left atrial enlargement and the influence on conduction system in acute rheumatic fever. The aim of this study is to investigate atrial electromechanical delay and P-wave dispersion in patients with acute rheumatic fever. ⋯ This study shows the prolongation of P-wave dispersion and interatrial electromechanical delay in acute rheumatic fever. Left atrial enlargement can be one of the underlying reasons for the increase in P-wave dispersion and interatrial electromechanical delay.

Case ReportsCardiac tamponade as an initial manifestation of systemic lupus erythematosus in a child.
Cardiac involvement is a rare initial presentation of systemic lupus erythematosus. An 11-year-old girl was described to have massive haemorrhagic pericardial effusion and cardiac tamponade, which was later diagnosed as systemic lupus erythematosus. Therefore, in children presenting with cardiac tamponade, systemic lupus erythematosus should be considered as one of the differential diagnoses, as morbidity and mortality associated with cardiac tamponade can be dramatically reduced with early diagnosis and use of steroids.
