Thirteen patients underwent transcatheter closure of coronary artery fistulas using interlocking detachable coils alone or combined with fibered coils. Complete occlusion was achieved in 92% of patients; although inadvertent embolization of coils occurred in 23% of patients, all these coils were easily retrieved using snares.
Colour Doppler flow mapping was used to determine the time of closure of the arterial duct in 51 healthy newborn infants. Initial time of closure corresponded with previous reports: 20% on the first day, 82% by the second day, 96% by the third day, and 100% by the fourth day. Twenty infants were delivered by caesarean section and followed up for seven days(More)
Doppler ultrasound was used to assess the pressure drop between the ventricles in 109 infants and children (61 less than two years old) with a ventricular septal defect who underwent cardiac catheterisation. The pressure in both ventricles was measured at catheterisation in 103 patients either simultaneously through two catheters (41) or with a single(More)
The Doppler spectral pattern of flow through the ductus arteriosus was studied in 117 patients. In 37 who underwent catheterisation, Doppler records and aortic and pulmonary artery pressure were available (21 simultaneously with two catheters) for review while the others had surgical ligation of the duct on the basis of the results of non-invasive tests.(More)
Nine children, aged 2.5 months to 16 years, presenting with tachyarrhythmias were treated with intravenous (i.v.) flecainide, a type 1C antiarrhythmic drug. There were four boys and five girls; seven were supraventricular and two ventricular tachycardias and three had structural cardiac abnormalities. The i.v. dose required to terminate the arrhythmias(More)
Apraclonidine, a selective alpha(2)-agonist, was developed to lower intraocular pressure and minimize the systemic side effects associated with the use of its parent drug, clonidine.(1) An investigation of the site of action of apraclonidine incidentally uncovered a reversal of anisocoria in patients with absent sympathetic innervation of one pupil (Horner(More)
A case of amniotic band syndrome (ABS) presenting with acalvaria is reported. ABS includes a spectrum of non-genetic anomalies, varying from simple digital band constriction to major craniofacial and visceral defects, and even fetal death. Acalvaria is a rare congenital malformation characterised by the absence of the dome-like superior portion of the(More)
Purpose To investigate the ophthalmic manifestations of paranasal sinus mucocoeles. Methods A retrospective study of all patients (1992–1998) diagnosed with paranasal sinus mucocoeles. All patients had a CT scan. Results Of the 45 patients, only 3 (6.7%) did not have ophthalmic symptoms or signs. The most common (64.4%) presenting feature was peri-orbital(More)
PURPOSE To investigate agreement between computerized and conventional methods for obtaining Hess charts and to compare relative ease of use of both methods. METHODS Hess charts of 65 patients were obtained by the use of the computerized Assaf Ocular Motility Analyzer (OMA) and the conventional Lees screen method. The Hess charts produced by each method(More)
The variability of the valve gradient measured by Doppler in pulmonary stenosis was compared with the variability of the gradient measured at catheterisation in 42 infants and children undergoing catheterisation with a view to balloon dilatation of the pulmonary valve. The maximum value measured by Doppler when the patient was unsedated was significantly(More)
