You are incorrect - aortic valve regurgitation may result as a complication of a small ventricular septal defect in the membranous septum.


Your choice: Cyanosis / polycythemia
Cyanosis and polycythemia do not occur as a direct result from the presence of a small ventricular septal defect, as such a defect produces no right-to-left shunt. In patients with an uncomplicated small defect, right ventricular pressure remains normal.
