Disturbances Of The Heart
If stenosis is actually present in this location, the lesion is
probably congenital. It might occur after a serious acute infectious
endocarditis, but then it would be associated with other lesions of
the heart. It has been found to be associated with such congenital
lesions of the heart as an open foramen ovale or foramen Botalli, or
with an imperfect ventricular septum, and perhaps with tricuspid
stenosis--in short,
cardiac congenital defect. The right ventricle
becomes hypertrophied, if the child lives to overcome the
obstruction.
The physical sign is a systolic blow at the second intercostal space
on the left; but as just stated, such a murmur must surely be
dissociated from an aortic murmur if found to develop after
babyhood, and it should also be diagnosed from the frequently
occurring hemic, basic and systolic murmurs; that is, if signs of
pulmonary lesions are not heard soon after birth or in early
babyhood, the diagnosis of pulmonary defects can be made only by
exclusion.
Unless the right ventricle is found later to be in trouble, there is
no treatment for this condition. If the right ventricle dilates,
digitalis may be of benefit.
