You are incorrect - aortic valve regurgitation may result as a complication of a small ventricular septal defect in the membranous septum.
Your choice: Congestive heart failure
Congestive heart failure does not occur as a direct result of a small ventricular septal defect. If congestive heart failure occurs in a patient with a documented small defect, additional etiologic factors such as infective endocarditis or anemia must be considered.
