Twenty two children (age range 4 months-20 years) with pulmonary valve stenosis and ten children (age range 1 month-11 years) with coarctation of the aorta underwent balloon dilatation in the 29 month period between October 1983 and February 1986. Number 5-9 French catheters with 5-20 mm balloons were used according to the size of the angiographically measured pulmonary valve annulus or coarcte...

Double outlet right ventricle (DORV) is a congenital heart disease in which the great arteries (aorta and main pulmonary artery) arise from the right ventricle (RV), with concomitant ventricular septal defect (VSD), usually non-restrictive. Double outlet right ventricle can be accompanied by other cardiovascular anomalies, such as ventricular hypoplasia, restrictive septal defects and various p...

A 46-year-old woman presented with a 6-month history of dyspnea and weight loss on a background of previous pneumonectomy for bronchial adenoid cystic carcinoma 14 years beforehand. Several years prior to this presentation, she had developed left vocal cord palsy and a metastatic lesion to the right buttock confirmed at resection. Investigations included CT pulmonary angiography and right heart...

The pulmonary blood vessels are richly inervated with fibres derived from both the sympathetic and parasympathetic nervous systems (Larsell, 1951; Mitchell, 1956) but attempts to demonstrate vasomotricity have yielded conflicting results. If the sympathetic fibres have a pulmonary vasomotor action, it might be anticipated that the administration of an adrenergic-blocking agent would have some d...
