A child with aortic stenosis has aortic regurgitation, and the physician has recommended valve replacement surgery. His parents want to know which aortic valve prosthesis is best for their child. What type of valve would be best in this case?
  1. Mechanical valve
  2. Bioprosthetic valve
  3. Pulmonary autograft
  4. Aortic homograft
Explanation
Answer: C - A pulmonary valve autograft is best for children and young adults who have aortic stenosis as the patients will not require long-term anticoagulation. The Ross procedure is the commonly performed operation that uses this technique: the patient's own pulmonary valve is used to replace the diseased aortic valve.
