OBJECTIVE To assess the influence of the pulmonary annulus diameter after reconstruction of the right ventricular (RV) outflow tract at repair of tetralogy of Fallot on pulmonary regurgitation and RV pressure load; and to evaluate the impact of pulmonary regurgitation on RV size and function. SETTING Paediatric cardiology and diagnostic radiology departments of a tertiary referral centre. P...

Tumours of the heart are not common. Benjamin (1939) reports the incidence of primary tumours as 0 03 per cent of 40,000 autopsies. Nearly 50 per cent of these primary tumours are myxomata or myxomatous polyps. Yater (1931) (77 cases), Mahaim (1945) (82 cases) and Pritchard (1951) (125 cases) have collected and reported cases and the number reported is probably still less than 250. Approximatel...

congenital defects of the pericardium are considered rare. until 1979 , the reported cases were only about 200.1 total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 before the last decade, the di...

DIAGNOSTIC angiocardiography necessitates the injection of large amounts of contrast medium into the circulation. In response to such injections a transient fall in systemic arterial blood pressure and an increase in heart rate of approximately 2 minutes' duration have been reported in human beings" 2 and in animals.3 Also, a transient cutaneous erythema is well recognized subsequent to the inj...

During the past few years angiocardiography has become one of the routine methods in the investigation of congenital heart disease. The development of the technique has increased its diagnostic value so that it offers a method of judging not only the anatomical, but also the pathophysiological aspects of a heart disease. This paper deals with a problem often met with in angiocardiography, i.e. ...

The hyperosmolality of current ionic angiographic media gives rise to several adverse effects. Use of the first low-osmolality medium, metrizamide (Amipaque), has been inhibited by expense and by the necessity for prior mixing into solution. Hexabrix is the first of such media to be available in stable solution, and its use in angiocardiography is reported, in direct comparison with Urografin, ...
