title: [Subpulmonary obstruction caused by an aneurysm of the membranous ventricular septum. A study of 2 cases].
abstract: Aneurysms of the membranous ventricular septum can exceptionally produce subpulmonary obstruction. We report two patients, an 8-year-old and a 2-year-old respectively, with a perimembranous ventricular septal defect and subpulmonic stenosis caused by an aneurysm of the membranous septum. Diagnosis was made by Doppler two-dimensional echocardiography and was confirmed by cardiac catheterization and was surgery. It is shown that this obstruction may appear late due to the growth of the aneurysm. In conclusion, we believe that the appearance of an aneurysm on a ventricular septal defect is not always beneficial, as it may result in right ventricular outflow tract obstruction or other kinds of complications which may require cardiac surgery.
