AIM To assess initial experience of cardiac catheterisation in children by the transhepatic approach where conventional venous access is impossible. PATIENTS AND METHODS Percutaneous transhepatic cardiac catheterisation was performed on six occasions in five children (three male) aged 4 to 36 months (mean 17 months). All children had documented femoral(More)
Syncope in childhood is very common. The vast majority of episodes are benign, and are due to neurocardiogenic syncope. Only a minority are due to something potentially more serious or life threatening. The diagnosis and differentiation of benign from more serious causes of syncope is made primarily by the history. Investigations are often unfruitful. The(More)
Syncope in childhood is a common problem. In most children, syncope is benign, secondary to a disturbance in autonomic control of heart rate and blood pressure. It is increasingly evident that neurally mediated syncope is a heterogeneous group of conditions, necessitating a reclassification of autonomic disorders. New entities, such as postural orthostatic(More)
OBJECTIVE To examine autonomic function as assessed by heart rate variability in patients 10 or more years after repair of tetralogy of Fallot, and to relate this to cardiac structure, function, and electrocardiographic indices. METHODS Heart rate variability was measured by standard time domain techniques on a 24 hour Holter ECG in 28 patients, aged 12(More)
BACKGROUND Subcutaneous implantable cardioverter defibrillator (S-ICD) systems have no components in contact with the heart and may avoid complications such as lead fracture, venous obstruction, or endocarditis that occur with transvenous leads. Concerns have been raised regarding inappropriate shocks and pocket erosion with S-ICD systems. We have compared(More)
OBJECTIVE To assess the quality of echocardiographic images from neonates transmitted over Integrated Service Digital Network 2 (ISDN2) channels. DESIGN Echocardiographic images were viewed live in real time either by a direct video link or by transmission over the commercial network, using one, two, or three ISDN2 channels. The order of the viewing(More)
There have been few reports of the use of extracorporeal life support (ECLS) to provide cardiac support in children with low cardiac output as a result of arrhythmias. We present two patients in whom venoarterial ECLS was used to provide support for cardiogenic shock secondary to intractable supraventricular tachycardia. In both cases, the arrhythmia(More)
In simple transposition of the great arteries (sTGA), balloon atrial septostomy is performed prior to arterial switch to improve mixing of systemic and pulmonary circulations. Following septostomy, some patients are also given prostaglandin E2 (PGE2) until surgical repair. The aims of our study were to identify how often PGE2 is given after septostomy, the(More)
