Abstract
The incorporation of the bulbus cordis into the definitive heart is so often imperfect that among cardiac anomalies defects in the outflow tract of the right ventricle are common. Occasionally, however, after the fundamental structures of the heart have been completed, stenosis of the pulmonary valve develops. This lesion, according to Abbott,1is "practically always inflammatory, the result of an endocarditis running its course late in foetal life." White2agreed that pulmonary stenosis is "almost invariably the result of congenital defects." As already intimated, uncomplicated pulmonary stenosis is rare; in 1,000 cases of congenital heart disease studied statistically by Abbott only 9 cases were listed. Levine3stated in his chapter on congenital heart disease, "Pulmonary stenosis as an isolated lesion is quite rare." References to uncomplicated pulmonary stenosis associated with bundle branch block have not been found. Bundle branch block has been the subject of much investigationThis publication has 1 reference indexed in Scilit:
