Abstract
|
|
|
The subvalvular pulmonary stenosis causing right ventricular hypertrophy is a relatively rare malformation and may be represented as a part of the spectrum of the double-chambered right ventricle(DCRV), in which anomalous muscle bundle at the
junction
of the main cavity of the right ventricle and the infundibulum produces a stenosis of the proximal portion of the infundibulum and divides the cavity into two chambers. The prevalence of this entity is reported to vary from 2 to 5% of all cases
of
obstructive lesions in the right ventricular out-flow tract (RVOT). Associated congenital abnormalities, most frequently including ventricular septal defect, have been found over 80% or more. In addition to 2-D echocardiography, cardiac
catheterization
and angiography provide the guide for operation.
We report a surgically corrected case of a adult female patient with isolated DCRV which was accompanied by palpitation with marked RVH and review the literature.
